ABSTRACT

 

Manganese supported titanium tungstate {TiMn(II)W} was synthesized by ion- exchange method and characterized by DSC and FTIR techniques. Its catalytic activity for epoxidation of cyclohexene using dry tert-butylhydroperoxide (TBHP) as an oxidant was studied. In the epoxidation reaction, under optimized condition cyclohexene was oxidized to cyclohexene oxide, cyclohexenol and cyclohexenone. A maximum 67.49% selectivity for epoxidation of cyclohexene was observed for Ti Mn(II)W/dryTBHP system after 6 hours of reaction when concentrations of the catalyst and the substrate were 0.20 mmole and 20 mmole respectively.
