Synthesis of Styrene Oxide from Styrene Through Epoxidation over Highly Stable Co2 +-NaX Catalyst
Pages: 256-261
Year: Issue:  3
Journal: Petrochemical Technology

Keyword:  固态离子交换Co2 +-NaX催化剂苯乙烯分子氧环氧化环氧苯乙烷;
Abstract: 将5次固态离子交换制备的Co2 +-NaX于500 ℃焙烧6 h,再进行一次固态离子交换制备高稳定性Co2 +-NaX催化剂.ICP表征结果表明,所制备的高稳定性Co2 +-NaX催化剂中Co2 +质量分数为9.13%,高于5次固态离子交换制备的Co2 +-NaX的平衡Co2 +质量分数(8.42%).将高稳定性Co2 +-NaX催化剂用于以分子氧为氧源的苯乙烯环氧化反应,考察了搅拌转速、催化剂用...
