乙二醇(EG)是一种重要的有机化工原料,主要用于生产聚酯纤维和防冻剂,此外还可用于生产不饱和聚酯树脂、润滑剂、增塑剂、非离子表面活性剂以及炸药等,用途十分广泛。1生产技术现状我国乙二醇的生产技术主要有以乙烯为原料,经环氧乙烷生产乙二醇的石油路线,此外还有以煤或者天然气为原料,先制得合成气(CO+H_2)后,再通过直接法或者间接法制得乙二醇的煤化工路线。1.1石油路线石油路线是以乙烯为原料,经环氧乙烷生产乙
Ethylene glycol (EG) is an important organic chemical raw material used mainly in the production of polyester fibers and antifreeze, as well as in the production of unsaturated polyester resins, lubricants, plasticizers, nonionic surfactants and Explosives, etc., a very wide range of uses. 1 Production technology status China’s ethylene glycol production technology mainly ethylene as raw material, ethylene glycol ethylene oxide production line, in addition to coal or natural gas as raw material, the first syngas (CO + H_2) After that, the coal chemical route of ethylene glycol is obtained by the direct method or the indirect method. 1.1 petroleum route petroleum route is based on ethylene as raw material, ethylene oxide production B
