Ethylene glycol, also known as "glycol", "ethylene glycol", referred to as the EG. The formula (CH2OH) 2, is the most simple diol. Ethylene glycol is a colorless, odorless, sweet liquid, toxic to animals, the human lethal dose of about 1.6 g / kg. Glycol with water, acetone miscible but less soluble in ethers. Used as a solvent, antifreeze, polyester and synthetic raw materials. Polymers of ethylene glycol polyethylene glycol (PEG) is a phase transfer catalyst, but also for cell fusion; which nitrate is an explosive.

Chemical Properties:

Due to its low molecular weight, lively nature, can play esterification / etherification / Aging / oxide / acetal / dehydration reaction.
Similar to ethanol, can generate major inorganic or organic acid ester, generally the first and only one hydroxyl group reacts by increasing the temperature, increasing the amount of acid, etc., can make two hydroxyl groups to form an ester. Such as mixed with sulfuric acid and nitric acid, is formed dinitrate. Acid chloride or anhydride of the two hydroxyl groups readily form esters. In ethylene glycol (manganese dioxide, aluminum oxide, zinc oxide or sulfuric acid) heating the catalyst can be intramolecular or intermolecular dehydration. Glycol with an alkali metal or alkaline earth metal alkoxides action. Typically the metal was dissolved in glycols, only one yuan alcohol; salts such as this alkoxide (such as sodium ethylene glycol) was heated to 180 ~ 200 ¡ă C in a stream of hydrogen, to form disodium ethylene glycol and ethylene glycol . Further heating together with ethylene glycol and 2 moles of sodium methylate, disodium ethylene glycol can be obtained. Disodium ethylene glycol is reacted with an alkyl halide to form an e
