Abstract

Molybdenum and tungsten catalysts, PAF-30-Mo and PAF-30-W, synthesized based on a porous aromatic framework PAF-30 have been tested in the epoxidation of cyclohexene with tert-butyl hydroperoxide. The influence of the temperature and the substrate to oxidant ratio on the characteristic features of the process has been studied. It has been shown that the catalysts exhibit high activity and make it possible to obtain cyclohexene epoxide in a high yield; however, they lose their activity over time due to the leaching of the metal from the pores of the polymer.

基于多孔芳构架的环己烯环氧化催化剂

摘要

基于多孔芳族骨架PAF-30合成的钼和钨催化剂PAF-30-Mo和PAF-30-W已在环己烯与叔丁基氢过氧化物的环氧化中进行了测试。研究了温度和底物与氧化剂的比例对工艺特征的影响。已经表明，该催化剂表现出高活性，并可以高收率获得环己烯环氧化物。然而，由于金属从聚合物的孔中浸出，它们随着时间的流逝失去了活性。
