Applications of Isophorone:
The partly hydrogenated derivative trimethylcyclohexanone is used in production of polycarbonates. 
Isophorone condenses with phenol to give an analogue of bisphenol A. 

Polycarbonates produced by phosgenation of these two diols produces a polymer with improved thermal stability.
Trimethyladipic acid and 2,2,4-trimethylhexamethylenediamine are produced from trimethylcyclohexanone and trimethylcyclohexanol. 

They are used to make specialty polyamides. 
Hydrocyanation gives the nitrile followed by reductive amination gives isophorone diamine. 
This diamine is used to produce isophorone diisocyanate which has certain niche applications.

Full hydrogenation gives 3,3,5-Trimethylcyclohexanol, a precursor to both sunscreens and chemical weapons.

Structure and reactivity of Isophorone:
Isophorone undergoes reactions characteristic of an α,β-unsaturated ketone. 
Hydrogenation gives the cyclohexanone derivative. 
Epoxidation with basic hydrogen peroxide affords the oxide.

Isophorone is degraded by attack of hydroxyl radicals.

Photodimerization of Isophorone:
When exposed to sunlight in aqueous solutions, isophorone undergoes 2+2 photocycloaddition to give three isomeric photodimers. 
These "diketomers" are cis-syn-cis, head to tail (HT), cys-anti-cys (HT), and head-head (HH). 
The formation of HH photodimers is favored over HT photodimers with increasing polarity of the medium.

Natural Occurrence of Isophorone:
Isophorone occurs naturally in cranberries.

Synthesis of Isophorone:
Isophorone is produced on a multi-thousand ton scale by the aldol condensation of acetone using KOH. 
Diacetone alcohol, mesityl oxide, and 3-hydroxy-3,5,5-trimethylcyclohexan-1-one are intermediates. 
A side product is beta-isophorone, where the C=C group is not conjugated with the ketone.

History of Isophorone:
The use of isophorone as a solvent resulted from the search for ways to dispose of or recycle acetone, which is a waste product of phenol synthesis by the Hock method.

Production of the solvent isophorone started in 1962 in the Herne nitrogen works of Hibernia AG. 
The development of the new solvent resulted from the search for ways in which to dispose of or recycle acetone. 
In 1967 Isophorone production was carried out in what is today the Herne plant of Evonik Industries AG and was previously the Hibernia factory Herne I.

Putting the first production plant into operation in 1967 signaled the start of acetone chemistry in Herne that was intended to position the site for the future and that still provides Isophorone with security today. 
When VEBA AG reorganized Isophorone chemical business, the Herne plants were transferred to Hüls AG in 1979 and so was the Isophorone product family. 
Since 1992 product variants of Isophorone and since 1999 Isophorone are today also manufactured at the Evonik site in Mobile, Alabama.

Isophorone has excellent solvent properties for binders, resins, and numerous chemical products. 
Isophorone is used as high boiling solvent in paints, printing inks and adhesives. 

In these applications Isophorone improves flowing properties and brightness. 
Because of Isophorone special chemical structure, Isophorone serves as starting material for production of several chemicals, which otherwise are hardly producible. 

These Isophorone derivatives are used in many different areas. 
In the construction industry, for example, they are used as corrosion protection on bridges, scaffolding or sluices. 
They are used in wood preservatives and to seal floors.

Safety of Isophorone:
The LD50 value of isophorone in rats and rabbits by oral exposure is around the 2.00 g/kg.
The safety aspects of isophorone have been subject to several studies.

First Aid of Isophorone:
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 Isophorone:
Use water spray, powder, foam, carbon dioxide.

Fire Fighting Procedures of Isophorone:
Do not extinguish fire unless flow can be stopped. 
Use water in flooding quantities as fog. 

Solid streams of water may be ineffective. 
Cool all affected containers with flooding quantities of water. 

Apply water from as far a distance as possible. 
Use "alcohol" foam, dry chemical or carbon dioxide.

If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped or safely confined. 
Use water in flooding quantities as fog. 
Solid streams of water may be ineffective. 

Cool all affected containers with flooding quantities of water. 
Apply water from as far a distance as possible. 
Use "alcohol" foam, dry chemical or carbon dioxide.

Use water spray to keep fire exposed containers cool. 
Use flooding quantities of water as fog or spray, dry chemical, foam, or carbon dioxide.

Spillage Disposal of Isophorone:
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of Isophorone. 
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.

Cleanup Methods of Isophorone:
If leak or spill has not ignited, use water spray to disperse vapors & to protect men attempting to stop leak.

Environmental considerations: Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. 
If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner.

Dike surfact flow using soil, sand bags, foamed polyurethane, or foamed concrete.

Preventive Measures of Isophorone:
Irrigate eyes with water. 
Wash skin with abundant quantities of water.

The scientific literature for the use of contact lenses in industry is conflicting. 
The benefit or detrimental effects of wearing contact lenses depend not only upon Isophorone, but also on factors including the form of Isophorone, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. 

However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. 
In those specific cases, contact lenses should not be worn. 
In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. 
Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. 
Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

Personnel protection: Avoid breathing vapors. 
Keep upwind.
Do not handle broken packages unless wearing appropriate personal protective equipment. 
Wash away any material which may have contacted the body with copious amounts of water or soap and water.

Reactivity Profile of Isophorone:
Ketones, such as ISOPHORONE, are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). 
The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. 

Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. 
Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. 

They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. 
Forms explosive peroxides.
