摘要
以H_2O_2为氧化剂,B-TS-1为催化剂催化1-己烯环氧化合成了1,2-环氧己烷。研究了B含量、溶剂、H_2O_2用量、温度、催化剂用量以及反应时间对反应的影响。B-TS-1在甲醇中表现出较低的催化活性和选择性,而在乙腈中表现出较高的催化活性和选择性。说明B^(3+)的引入改变了TS-1的疏水性,乙腈溶剂的采用可能改变了反应的历程。
Epoxidation of 1 -hexene was carried out using H202 as the oxidant and 15 -13 - t as me catalyst. effects of B concent, solvent, H2 02 concentration, reaction temperature, catalyst concentration, and reaction time on the epoxidation of 1 -hexene were studied. The catalyst showed low catalytic activity and selectivity when methanol was used as a solvent, while it showed higher catalytic activity and selectivity when aeetonitrile was used as the solvent. This effect was due to the changes in the hydrophobic character of TS - 1 caused by the incorporation of B3 + , which might alter the reaction pathway when acetonitrile was used as the solvent.
