Description
(ethylene glycol and glycol) name "glycol", "1, *-monooxygenase and
ethyl glycol, EG" referred to. For HOCH2 â‚‚ (patent), is the most
simple glycol. Glycol is a colorless, odourless, has a sweet taste
of animals is toxic, liquid, human fatal dose of about 1.6 g/kg.
Glycol can with water, acetone mutually dissolved, but in ethers
solubility in small. Used as a solvent, antifreeze and synthetic
polyester materials. The morphology of polyethylene glycol (PEG
chloropropanoic) is a kind of phase transfer catalyst, and also in
cell fusion; Its nitric acid ester is a kind of explosives.
Usage :
1.Freeze protection, heat transfer and hydraulic fluids; natural
gas
and hydrocarbon treating agents;
2.Hydroscopic agents for paper, cork and textile conditioning;
3.Plasticizer formulations and raw materials for ester and
polyester production.
4.The ethylene glycol family’s solvency properties are useful
in
custom formulation of paints, dyes, inks.

Due to the low molecular weight, nature and lively, can the
esterification/etherification/alcoholize/oxidation/acetal/dehydration
and reaction. With ethanol similar, main can and inorganic or
organic acid reacts ester, first commonly only a hydroxyl reaction,
the raising temperature, increase acid amount, can make two
hydroxyl groups has formed ester. Such as and mixed with sulfuric
acid, nitric acid of reaction is formed two nitric acid ester.
Carbonyl chlorides or anhydride easily to make two hydroxyl form
ester. Glycol in catalyst (manganese dioxide, alumina, zinc oxide
or sulfuric acid) under the action of heat, can happen between the
molecules in the molecular or water loss. Glycol can and alkali
metal or alkaline earth metal role in the formation of salt
alcohol. Usually the metal soluble in glycol, only one yuan alcohol
salt; Such as the alcohol salt (such as ethylene glycol) in a
sodium hydrogen flow heated to **0 ~ **0 ° C, can form glycol and
glycol two sodium. In addition with ethylene glycol and 2 Moore
sodium methoxide heat, and can be together to glycol two sodium.
Glycol two sodium and halogenated silane reaction, generating
glycol single ether or double ether. Glycol two sodium and 1,-two
br ethane reaction, and to generate two oxygen six ring. In
addition, glycol also to oxidation, along with the antioxidant or
reaction conditions, can create all kinds of different products,
such as ethanol HOCH2CHO aldehyde, b dialdehyd OHCCHO, ethanol
acid, oxalic acid, HOCH2COOH HOOCCOOH and carbon dioxide and water.
A glycol and glycol, the other different periodate oxidation can
happen carbon chain rupture. Application glycol can often replace
glycerin use. In leather and pharmaceutical industry, for water
mixture, and solvent. The derivatives of ethylene glycol two
nitrato is explosive. Ethylene glycol single methyl ether or single
ether is a good solvent, such as a soluble fiber agent HOCH2CH2OCH3
soluble fiber, resin, paint and many other organisms. The
dissolution of the ethylene glycol ability, but it easy to
metabolism of oxygen, and to generate poisonous oxalic acid,
therefore is not widely used as a solvent. Glycol is a antifreeze
agent, *0% of glycol solution in *0 ° C-when ice.
