摘　　要：当苯酚与环氧乙烷的物质的量比为 1. 05∶1,有机碱A和无机碱A的重量比为 1∶1,二价金属离子用量是复合催化剂的 0. 5%时,催化剂的催化效果比较好,乙二醇苯醚选择性可提升到 99%,产品铂 钴比色为 50号左右。The optimum conditions for synthesis of ethylene glycol phenyl ether are as follows: the substance ratio of phenol to ethylene oxide is 1.05∶1, the weight ratio of organic base to inorganic base is 1∶1, the dosage of complex catalyst based on bivalent metal ion is 0.5%. Under these conditions the selectivity of ethylene glycol phenyl ether reaches to 99% with chroma of about 50.
