Abstract:

 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.
