The nature and use of ethylene glycol and ethanol is similar to the main inorganic or organic acid capable of forming the ester, typically only one hydroxyl group reacts first, by increasing the temperature, increasing the amount of acid, etc., can have two hydroxyl groups to form an ester. Such as nitric acid mixed with sulfuric acid in the reaction with the formation dinitrate. Acid chloride or anhydride is easy to make two hydroxyl groups to form an ester. Ethylene glycol under (manganese dioxide, aluminum oxide, zinc oxide or sulfuric acid) catalyst is heated, may occur intramolecular or intermolecular dehydration. Glycol instead of glycerin can often be used. In the leather and pharmaceutical industries glycol, were used as a wettable powder and solvent. Ethylene glycol dinitrate is a derivative of explosives. Ethylene glycol monomethyl ether or monoethyl ether is a good solvent, such as methyl cellosolve HOCH2CH2OCH3 soluble fibers, resins, paints and many other organic compounds. Ethylene glycol strong dissolving power quality assurance, but it is easily oxidized metabolism, formation of toxic oxalic acid, and therefore can not be widely used as a solvent. Ethylene glycol is an antifreeze, 60% ethylene glycol solution freezes at -40 ° C.
