Ethylene glycol CAS 107-21-1,
Purity: ≥ 99.9%
ethylene glycol, the simplest member of the glycol family of organic compounds. A glycol is an alcohol with two hydroxyl groups on adjacent carbon atoms (a 1,2-diol). The common name ethylene glycol literally means “the glycol derived from ethylene.”
Also called: ethane-1,2-diol
Ethylene
glycol is a clear, sweet, slightly viscous liquid that boils at 198 °C
(388.4 °F). Its most common use is as an automotive antifreeze. A 1:1
solution of ethylene glycol and water boils at 129 °C (264.2 °F) and
freezes at ?37 °C (?34.6 °F), serving as an excellent coolant in
automotive radiators. Ethylene glycol is highly poisonous; animals or
humans that drink the solution become very ill and may die.
In
addition to its use in antifreeze, ethylene glycol is used as an
ingredient in hydraulic fluids, printing inks, and paint solvents. It is
also used as a reagent in making polyesters, explosives, alkyd resins,
and synthetic waxes.
