Triethylene glycol (CAS 112-27-6)


Triethylene glycol (CAS 112-27-6)

Triethylene glycol, TEG, or triglycol is a colorless odorless viscous liquid with molecular formula HOCH2CH2OCH2CH2OCH2CH2OH. It is used as a plasticizer for vinyl polymers. It 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. It is an additive for hydraulic fluids and brake fluids and is used as a base for “smoke machine” fluid in the entertainment industry.

Triethylene glycol is a member of a homologous series of dihydroxy alcohols. It 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. It is also soluble in ethanol, acetone, acetic acid, glycerine, pyridine, aldehydes; slightly soluble in diethyl ether; and insoluble in oil, fat and most hydrocarbons.
