Applications
1.Glycol, also known as glycol, is the simplest aliphatic diol, with the chemical properties of alcohols, such as ether, ester, can be oxidized to aldehyde or acid, condensation to produce ether.
2.It can also be replaced by a halogen.In reaction with acyl chloride or anhydride, diesters are generally formed.Heated in the presence of a catalyst (manganese dioxide, alumina, zinc oxide or sulfuric acid), it is dehydrated within or between molecules to produce circular glycol acetal, which reacts with nitric acid to produce glycol dinitrate (an explosive).Ethylene glycol is a raw material for the production of polyester resins, alkyd resins, and polyester fibers.
3.It is also used as an automobile antifreeze and as a refrigerant for flying Chemicalbook engines. In 1980, the amount of ethylene glycol used as an antifreeze was equal to the amount used to produce polyester in the United States.In addition, polyester fiber and other high molecular compounds can be synthesized.The combination of ethylene glycol dinitrate and nitroglycerin can reduce the freezing point of the explosive.
