High purity 99% Ethylene glycol cas 107-21-1
Ethylene Glycol, also known as glycol, is the simplest aliphatic glycol, with the chemical properties of alcohols,
such as the formation of ether, ester, can be oxidized to form aldehyde or acid, can condensation to form ether.
They can be replaced by halogens.React with acyl chloride or anhydride, form double ester commonly.
Heated by a catalyst (manganese dioxide, aluminum oxide, Zinc Oxide or sulfuric acid),
Ethylene Glycol can be dehydrated within or between molecules to form cyclic glycol glycol acetal, which reacts
with nitric acid to form glycol dinitrate (an explosive). Ethylene Glycol is the raw material for the production of
polyester resin, alkyd resin, polyester fiber, but also used as automobile antifreeze and aircraft engine refrigerant,
in 1980 the United States used for antifreeze glycol and polyester production of the same consumption.In addition,
can also synthesize polyester fiber and other polymer compounds.The freezing point of explosive can be reduced by
the combination of glycol dinitrate and nitroglycerin. Ethylene Glycol can also be used as raw material and
high boiling point solvent for drugs and plastics.Ethylene Glycol (ethylene glycol) was prepared from ethylene
oxide (ethylene oxide) as raw material by hydrolysis.
