Heterogenization of peracid onto the SBA-16 mesoporous silica for the epoxidation of cyclooctene

Epoxidation of olefins is an important process in organic synthesis. Organic peracids can react with olefins to give the corresponding epoxides. This process is a convenient and useful method which does not involve any catalyst. However, the use of peracids is not environmentally friendly as considerable amount of carboxylic acid waste are formed. Separation of the produced carboxylic acid from the reaction mixture and regeneration of the peracid is one way to reduce the chemical wastage. To solve this problem, we report our attempt to immobilization of the organic peracid on the surface of inorganic solid support(SBA-16). activity of the obtained supported peracid as well as its recyclability are investigated in the epoxidation of cyclooctene.
