Triethylene glycol, TEG, or triglycol is a colorless odorless viscous liquid with molecular formula HOCH2CH2OCH2CH2OCH2CH2OH.
Triethylene glycol is used as a plasticizer for vinyl polymers.
Triethylene glycol is also used in air sanitizer products, such as "Oust" or "Clean and Pure". When aerosolized it acts as a disinfectant. Glycols are also used as liquid desiccants for natural gas and in air conditioning systems.
Triethylene glycol is an additive for hydraulic fluids and brake fluids and is used as a base for "smoke machine" fluid in the entertainment industry.
Properties
Triethylene glycol is a member of a homologous series of dihydroxy alcohols.
Triethylene glycol is a colorless, odorless and stable liquid with high viscosity and a high boiling point. Apart from its use as a raw material in the manufacture and synthesis of other products, TEG is known for its hygroscopic quality and its ability to dehumidify fluids. This liquid is miscible with water, and at standard atmospheric pressure (101.325 kPa) has a boiling point of 286.5 °C and a freezing point of -7 °C.
Triethylene glycol is also soluble in ethanol, acetone, acetic acid, glycerine, pyridine, aldehydes; slightly soluble in diethyl ether; and insoluble in oil, fat and most hydrocarbons.

Preparation
Triethylene glycol is prepared commercially as a co-product of the oxidation of ethylene at high temperature in the presence of silver oxide catalyst, followed by hydration of ethylene oxide to yield mono(one)-, di(two)-, tri(three)- and tetraethylene glycols.
Applications
Triethylene glycol is used by the oil and gas industry to "dehydrate" natural gas.
Triethylene glycol may also be used to dehydrate other gases, including CO2, H2S, and other oxygenated gases.
Triethylene glycol is necessary to dry natural gas to a certain point, as humidity in natural gas can cause pipelines to freeze, and create other problems for end users of the natural gas.
Triethylene glycol is placed into contact with natural gas, and strips the water out of the gas.
Triethylene glycol is heated to a high temperature and put through a condensing system, which removes the water as waste and reclaims the TEG for continuous reuse within the system. The waste TEG produced by this process has been found to contain enough benzene to be classified as hazardous waste(benzene concentration greater than 0.5 mg/L).
Triethylene glycol is well established as a relatively mild disinfectant toward a variety of bacteria, influenza A viruses and spores of Penicillium notatum fungi.
Triethylene glycol is a colorless liquid with a mild odor. Dense than water.
Triethylene glycol is a poly(ethylene glycol) that is octane-1,8-diol in which the carbon atoms at positions 3 and 6 have been replaced by oxygen atoms.

Triethylene glycol (TEG) is a liquid higher glycol of very low vapor pressure with uses that are primarily industrial.
Triethylene glycol has a very low order of acute toxicity by iv, ip, peroral, percutaneous and inhalation (vapor and aerosol) routes of exposure.
Triethylene glycol (also known as TEG, triglycol and trigen) is a colourless, viscous, non-volatile liquid with the formula C6H14O4.
Triethylene glycol is well known for its hygroscopic quality and its ability to dehumidify fluids.
Triethylene glycol is prepared commercially as a co-product of the oxidation of ethylene at high temperature, in the presence of a silver oxide catalyst. The ethylene oxide is then hydrated to yield mono, di, tri, and tetra ethylene glycols.
Triethylene glycol is estimated that the total world consumption of TEG is in excess of 175 metric tonnes annually.
Oil & Gas Industry:
The main uses for tri ethylene glycol are based upon its hygroscopic quality. This means that it can absorb moisture from the air through absorption or adsorption. Triethylene glycol is used as a dehydrating agent for natural gas pipelines where it removes the water from the gas before being condensed.
The triethylene glycol can then be continually reused, although the by-product of benzene needs to be disposed of carefully.
Triethylene glycol is useful as it prevents the gas from freezing making the gas easier to transport and manage for end consumers.
Mild Disinfectant:
Triethylene glycol can also be used as a mild disinfectant. Due to its low toxicity, antimicrobial properties, and low odour, it is commonly used for air disinfection in occupied areas where more aggressive disinfectants cannot be used. Due to these disinfectant properties and the dehydrating properties, it is an ideal dehumidifying agent in air-conditioning units.
Uses:
-Antifreeze
-Coolants
-Chemical intermediates
-Gas dehydration and treating
-Heat transfer fluids
-Polyester resins
-Solvents
Benefits:
-Versatile intermediates
-Low volatility
-Low boiling point
