Applications of Methylbenzene:
Methylbenzene is used in paint and gas refineries, as well as other industrial operations, but Methylbenzene can be toxic when inhaled or ingested.
People working with Methylbenzene should be prepared by carrying a first-aid kit in case an emergency arises during work hours.
Different uses of Methylbenzene:
A solvent for paints and stains:
This is the most common use of Methylbenzene.
Methylbenzene dissolves oils with ease and evaporates quickly, making Methylbenzene the best choice for removing residual stains on walls or boards.
Methylbenzene use in paints is also very common.
Methylbenzene low cost and ability to dissolve pigments makes Methylbenzene a preferred solvent in paint production.
However, this makes Methylbenzene very dangerous to handle when paint spills are reported as inhalation may result in harmful exposure to this chemical compound.
Solvent for rubber cement:
Methylbenzene is also a good solvent for rubber cements because of Methylbenzene relative cheapness and ability to dissolve a variety of compounds.
Methylbenzene is especially good at dissolving rubber cement quickly, making Methylbenzene an ideal choice for sealing envelopes and keeping other stamps dry.
Solvent in the production of styrene-butadiene latexes:
Methylbenzene is also used as a solvent in the production of styrene-butadiene latexes; these are vital products in the production of tires, synthetic rubbers, adhesives and coatings.
This means that controlling Methylbenzene is extremely important for anyone wishing to work in a paint manufacturer or tire factory.
However, due to Methylbenzene toxicity in high concentrations, wearing adequate breathing apparatus when working with Methylbenzene may be advisable.
Solvent in the production of rubber chemicals:
Methylbenzene is sometimes used as a solvent in the production of rubber chemicals.
However, Methylbenzene is not widely used because other solvents are cheaper and more efficient.
Solvent for the extraction of oils:
Methylbenzene can also be used as a solvent to extract oils from food products such as olives.
This is extremely important because damaged fruit cannot be sold if Methylbenzene looks unappetizing and could even put people at risk of contracting food poisoning if eaten without processing.
Here again, since Methylbenzene has low boiling and vaporization points, Methylbenzene must be handled with care when transferred or processed using machinery.
Solvent in the production of automobile gasoline:
Aside from paints, Methylbenzene is also used as a solvent in the production of automobile gasoline.
Methylbenzene low boiling point and low cost make Methylbenzene a popular choice for refiners, especially with lower prices for high-octane blends.
The solvents removed from gasoline are more expensive than those produced by petroleum distillates and can be sold for as much as ten times more.
This explains why Methylbenzene is so commonly used by refiners in small quantities compared to other oligomerics such as dicyclopentadiene and tetradecafluoroethylene (CFCs).
Solvent for oil drilling:
Oil drillers often use a mixture of Methylbenzene and ethanol in their injection fluid to increase the efficiency of extraction.
This is because the two solvents relax the rock formations in order to increase the amount of oil extracted from those deposits.
This makes Methylbenzene necessary for them to wear proper protection when handling chemical equipment that comes into contact with this chemical compound.
Other drilling operations may also use diesel fuel mixed with Methylbenzene, but this mixture is more expensive and less convenient to transport.
This helps to answer the question what is Methylbenzene used for.
Solvent in the production of paints:
Methylbenzene is also used as a solvent in the production of paints that are made for rust-proofing.
Methylbenzene works by dissolving the paint and allowing Methylbenzene to penetrate deeper into the metal, making Methylbenzene ideal for use with vehicles exposed to water and elements.
However, Methylbenzene is not used in products intended for commercial or residential houses because of Methylbenzene toxicity when inhaled.
Solvent for removal of residual coatings from fabrics
Another use of Methylbenzene is as a solvent for removing residual coatings from fabrics such as polyester and cotton.
About 2-4% Methylbenzene is added to the mixture, which is then sprayed on one side of fabric.
In conclusion, Methylbenzene has a variety of uses and is widely used in industry.
However, as a result of Methylbenzene toxic nature when inhaled, any worker handling this chemical compound must take the following precautions:
(1)Use a respirator with a strong air supply in case Methylbenzene is being released into the atmosphere.
(2)Wear gloves whenever handling products containing Methylbenzene, especially paint and cleaning products that may cause exposure when spilled.
(3)Keep an eye on other workers in case they start to exhibit signs of dyspnea or respiratory distress, which are both symptoms of prolonged exposure.
Dyspnea means shortness of breath while respiratory distress is characterized by breathing through the mouth because air cannot be forced through the nose.
(4)Keep all equipment used for handling solvents away from the body as much as possible for maximum protection.

Fuel:
Methylbenzene can be used as an octane booster in gasoline fuels for internal combustion engines as well as jet fuel.
Methylbenzene at 86% by volume fuelled all the turbocharged engines in Formula One during the 1980s, first pioneered by the Honda team.
The remaining 14% was a "filler" of n-heptane, to reduce the octane rating to meet Formula One fuel restrictions.
Methylbenzene at 100% can be used as a fuel for both two-stroke and four-stroke engines; however, due to the density of the fuel and other factors, the fuel does not vaporize easily unless preheated to 70 °C (158 °F).
Honda solved this problem in their Formula One cars by routing the fuel lines through a heat exchanger, drawing energy from the water in the cooling system to heat the fuel.
In Australia in 2003, Methylbenzene was found to have been illegally combined with petrol in fuel outlets for sale as standard vehicular fuel.
Methylbenzene incurs no fuel excise tax, while other fuels are taxed at more than 40%, providing a greater profit margin for fuel suppliers.

Properties of Methylbenzene:
Methylbenzene is more reactive to electrophiles than benzene.
Due to the greater part of the methyl group than the electron-releasing properties, Methylbenzene reacts normal fragrant in the same position.
Methylbenzene faces sulphonation to provide an acid called p-Methylbenzenesulfonic and chlorination by Cl2 in the presence of FeCl3 to give ortho and para isomers of chloroMethylbenzene.
Chemical properties:
The distance between carbon atoms in the Methylbenzene ring is 0.1399 nm.
The C-CH3 bond is longer at 0.1524 nm, while the average C-H bond length is 0.111 nm.
Methylbenzene reacts as a normal aromatic hydrocarbon in electrophilic aromatic substitution.
Because the methyl group has greater electron-releasing properties than a hydrogen atom in the same position, Methylbenzene is more reactive than benzene toward electrophiles.
Methylbenzene undergoes sulfonation to give p-Methylbenzenesulfonic acid, and chlorination by Cl2 in the presence of FeCl3 to give ortho and para isomers of chloroMethylbenzene.
Importantly, the methyl side chain in Methylbenzene is susceptible to oxidation.
Methylbenzene reacts with potassium permanganate to yield benzoic acid, and with chromyl chloride to yield benzaldehyde (Étard reaction).
The C-H bonds of the methyl group in Methylbenzene are benzylic, which means that they are weaker than C-H bonds in simpler alkanes.
Reflecting this weakness, the methyl group in Methylbenzene undergoes halogenation under free radical conditions.
For example, when heated with N-bromosuccinimide (NBS) in the presence of AIBN, Methylbenzene converts to benzyl bromide.
The same conversion can be effected with elemental bromine in the presence of UV light or even sunlight.
Methylbenzene may also be brominated by treating Methylbenzene with HBr and H2O2 in the presence of light.
C6H5CH3 + Br2 → C6H5CH2Br + HBr
C6H5CH2Br + Br2 → C6H5CHBr2 + HBr
The methyl group in Methylbenzene undergoes deprotonation only with very strong bases; Methylbenzene pKa is estimated to be approximately 41.
Complete hydrogenation of Methylbenzene gives methylcyclohexane. The reaction requires a high pressure of hydrogen and a catalyst.
Miscibility of Methylbenzene:
Methylbenzene is miscible (soluble in all proportions) with ethanol, benzene, diethyl ether, acetone, chloroform, glacial acetic acid and carbon disulfide, but immiscible with water.
Structure of Methylbenzene:
Methylbenzene is widely used as an industrial raw material and a solvent for manufacturing many commercial products, including paints and glues.
Production of Methylbenzene:
Methylbenzene occurs naturally at low levels in crude oil and is a byproduct in the production of gasoline by a catalytic reformer or ethylene cracker.
Methylbenzene is also a byproduct of the production of coke from coal.
Final separation and purification is done by any of the distillation or solvent extraction processes used for BTX aromatics (benzene, Methylbenzene, and xylene isomers).
Other preparative routes:
Methylbenzene can be prepared by a variety of methods.
For example, benzene reacts with methanol in presence of a solid acid to give Methylbenzene:
C6H6 + CH3OH ->[t^o]C6H5CH3 + H2O
Manufacturing Methods of Methylbenzene:
Methylbenzene is possible to synthesize Methylbenzene industrially by alkylation of benzene with methanol, and by cyclization of n-heptane with subsequent aromatization.
However, for economic reasons Methylbenzene is extracted from reformates from crude petroleum distillates; liquid products from the pyrolysis of hydrocarbons (steam cracking) /and/ liquid products from the gasification or coking (pyrolysis) of coal, lignite, etc.
An important aspect of the extraction of Methylbenzene is the fact that the pyrolysis products (from steam cracking, coking, etc.) must be hydrogenated before pure Methylbenzene can be extracted.
The unsaturated components are converted to saturated ones and the heteroatoms such as sulfur, nitrogen, and oxygen are removed.
In the case of reformates such pretreatment is usually unnecessary.
For the separation of Methylbenzene from other components within the same boiling range several methods are available, depending on quality requirements.
Fine fractionation is now suitable only for the production of Methylbenzene with lower purity, and involves significant losses in fores and tails.
Azeotropic distillation uses entrainers, such as methanol, to separate Methylbenzene from nonaromatics; a nonaromatics - methanol fraction with a lower bp than the methanol - Methylbenzene azeotrope distills at the column head, while pure Methylbenzene is removed from Methylbenzene base.
Methanol is recovered from the distillate by washing with water.
For economic reasons, extractive distillation is now used only for the separation of Methylbenzene from nonaromatics.
Technical grade solvents with higher bp than Methylbenzene have proved to be suitable extraction agents, e.g., N-methylpyrrolidone (Distapex process, Lurgi Ol-Gas-Chemie), and morpholine (Morphylane process, Krupp-Koppers).
Extractive distillation essentially involves two distillation columns between which the extraction agent is circulated.
The Methylbenzene-containing material is charged to the extraction column; the extraction agent is charged to the column head.
The extraction agent - Methylbenzene mixture leaves the column at the bottom, and is separated into pure Methylbenzene and extraction agent in a second recovery column.
Methylbenzene obtained at the distillation head of the extraction column contains the nonaromatic components of the starting material and the extraction agent.
This fraction is separated in the recovery column into raffinate (nonaromatics) and extraction agent.
The latter is then combined with the main portion of extraction agent from the recovery column, and fed back into the extraction column.
Catalytic reforming of petroleum steams accounts for 87% of total Methylbenzene production.
An additional 9% is separated from pyrolysis gasoline produced in steam crackers during manufacture of ethylene and propylene coal-tar separation from coke ovens produces 1% of total Methylbenzene up to 2% of the Methylbenzene produced is obtained as a by-product from styrene manufacture.
(1) By catalytic reforming of petroleum.
(2) By fractional distillation of coal tar light oil.

History of Methylbenzene:
Methylbenzene was first isolated in 1837 through a distillation of pine oil by Pierre Joseph Pelletier and Filip Neriusz Walter, who named Methylbenzene rétinnaphte.
In 1841, Henri Étienne Sainte-Claire Deville isolated a hydrocarbon from balsam of Tolu (an aromatic extract from the tropical Colombian tree Myroxylon balsamum), which Deville recognized as similar to Walter's rétinnaphte and to benzene; hence he called the new hydrocarbon benzoène.
In 1843, Jöns Jacob Berzelius recommended the name toluin.
In 1850, French chemist Auguste Cahours isolated from a distillate of wood a hydrocarbon which he recognized as similar to Deville's benzoène and which Cahours named toluène.
Handling and Storage of Methylbenzene:
Nonfire Spill Response:
ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.
All equipment used when handling Methylbenzene must be grounded.
Do not touch or walk through spilled material.
Stop leak if you can do Methylbenzene without risk.
Prevent entry into waterways, sewers, basements or confined areas.
A vapor-suppressing foam may be used to reduce vapors.
Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers.
Use clean, non-sparking tools to collect absorbed material.
LARGE SPILL:
Dike far ahead of liquid spill for later disposal.
Water spray may reduce vapor, but may not prevent ignition in closed spaces.
Safe Storage of Methylbenzene:
Fireproof.
Separated from strong oxidants.
Storage Conditions of Methylbenzene:
Keep container tightly closed in a dry and well-ventilated place.
Containers which are opened must be carefully resealed and kept upright to prevent leakage.
Handle and store under inert gas.
Store in a flammable liquid storage area or approved cabinet away from ignition sources and corrosive and reactive materials.
Before entering confined space where this chemical may be present, check to make sure that an explosive concentration does not exist.
Methylbenzene must be stored to avoid contact with strong oxidizers (such as chlorine, bromine, and fluorine), since violent reactions occur.
Protect storage containers from physical damage.
Sources of ignition, such as smoking and open flames, are prohibited where Methylbenzene is used, handled, or stored in a manner that could create a potential fire or explosion hazard.
Metal containers involving the transfer of 5 gallons or more of Methylbenzene should be grounded and bonded.
Drums must be equipped with self-closing valves, pressure vacuum bungs, and flame arresters.
Use only nonsparking tools and equipment, especially when opening and closing containers of Methylbenzene.
Outside or detached storage is preferred.
Inside storage should be in a standard flammable liquids storage warehouse, room, or cabinet.
Separate from oxidizing materials.
First Aid Measures of Methylbenzene:
EYES:
First check the victim for contact lenses and remove if present.
Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center.
Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician.
IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
SKIN:
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing.
Gently wash all affected skin areas thoroughly with soap and water.
If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
INHALATION:
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air.
If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital.
Provide proper respiratory protection to rescuers entering an unknown atmosphere.
Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.
INGESTION:
DO NOT INDUCE VOMITING.
If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center.
Be prepared to transport the victim to a hospital if advised by a physician.
If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body.
DO NOT INDUCE VOMITING.
IMMEDIATELY transport the victim to a hospital.
Fire Fighting of Methylbenzene:
The majority of these products have a very low flash point.
Use of water spray when fighting fire may be inefficient.
SMALL FIRE:
Dry chemical, CO2, water spray or regular foam.
LARGE FIRE:
Water spray, fog or regular foam. Avoid aiming straight or solid streams directly onto the product.
If Methylbenzene can be done safely, move undamaged containers away from the area around the fire.
FIRE INVOLVING TANKS OR CAR/TRAILER LOADS:
Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles.
Cool containers with flooding quantities of water until well after fire is out.
Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
ALWAYS stay away from tanks engulfed in fire.
For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn.
Accidental Release Measures of Methylbenzene:
IMMEDIATE PRECAUTIONARY MEASURE:
Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
LARGE SPILL:
Consider initial downwind evacuation for at least 300 meters (1000 feet).
FIRE:
If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.
Spillage Disposal of Methylbenzene:
Evacuate danger area! Consult an expert! Personal protection:
Chemical protection suit and self-contained breathing apparatus.
Remove all ignition sources.
Do NOT wash away into sewer.
Do NOT let this chemical enter the environment.
Collect leaking and spilled liquid in sealable containers as far as possible.
Absorb remaining liquid in sand or inert absorbent.
Then store and dispose of according to local regulations.
