Progress in Synthesis of Ethylene Oxide from Ethylene

随着乙烯制环氧乙烷的工艺技术和催化技术的发展,综述了乙烯制环氧乙烷的技术进展。环氧乙烷广泛地应用在例如化工、医疗、军事、洗涤、印染等领域。现有的合成技术为乙烯直接氧化,常用银催化剂。发展趋势是对现有工艺进行优化,对银催化剂的性能进行改进以及对副反抑制剂的研究。

Based on the development of process technology and catalytic technology for the synthesis of ethylene oxide from ethylene,the technical progress in the synthesis of ethylene oxide from ethylene is reviewed. Ethylene oxide is widely used in chemical,medical,military,washing,printing,dyeing and other fields. The existing synthesis technology is the direct oxidation of ethylene,and silver is commonly used as the catalyst. The developing trend is to optimize the existing process,improve the performance of silver catalyst and study the side reaction inhibitors.
