摘要
综述了环氧乙烷和乙二醇生产技术在近年来发生的一系列改进。阐述了生产原料的多样化、乙二醇生产路线新开拓。环氧乙烷的生产进步主要有银催化剂的技术进步、反应器改进以及精制前路线的选择等;乙二醇的生产由传统直接水合法逐渐向催化法发展,以煤为原料来制备乙二醇成为新的选择。
The improvements of Ethylene oxide and ethylene glycol production technology in recent years was reviewed. Elaborated the diw,-rsification of production raw material and new EG production routes open up. The EO production progress mainly included silver catalyst technology advancement, improvements of the reactor and the route selection before refined; The EG production changed from the traditional straightforward hydration gradually to the development of catalytic hydration, coal as raw material to prepare EG became the new choice.
