Title
Cyclohexane mild oxidation catalyzed by new titanosilicate with hollow structure
Abstract

Titanium silicalite with hollow structure (HTS), was one new type of titanosilicate used in oxidation process. Its catalytic property on the mild oxidation of cyclohexane with hydrogen peroxide (H2O2) in liquid phase was investigated, and the difference of catalytic performance between HTS and compared sample (TS-1) was discussed. The results show cyclohexanone (K) and cyclohexanol (A) are the major products; with the increment of reaction temperature and reaction time, cyclohexane conversion and the yield of K increase, the selectivity to K increases while the selectivity to A decreases. It is found that hollow structure and different distributions of Ti species lead to above differences, and L acidity would be also concerned with their catalytic performance. In one word, HTS is one proper catalyst for application in the cyclohexane oxidation process with H2O2 as oxidant under mild conditions.
