Epoxidation of fatty acid Methyl Esters Catalyzed by [(CH2)5NH2]5BMO12O40 Catalyst

Abstract

The action of the title catalyst with H2O2 leads to a formation of homogeneous phase and an accelerated reaction rate. The catalyst will precipitate in solid particles with the consumption of H2O2 and the decreasing temperature, its recovery is up to 90% and catalytic activity is almost unchanged after six consecutive uses. The effect of reaction conditions on the epoxidation and H2O2 utilization was investigated. Under the conditions of reaction time 2.5h,catalyst 0.3g, stepwise addition of 30%H2O2 3.5（30.88 mmol, reaction temperature 65 ℃,1,2-dichloroethane 20 mL, FAMEs 5.0（22.84 mmol double bond, the product epoxy value is up to 5.78%,double bond epoxidation selectivity 81.9% and H2O2 utilization 86%.
