Soybean oil epoxidation with hydrogen peroxide using an amorphous Ti/SiO2 catalyst

Soybean oil epoxidation with hydrogen peroxide using an amorphous Ti/SiO2 catalyst We report a study of the epoxidation of soybean oil and soybean methyl esters with hydrogen peroxide in dilute solution (6 wt%) using an amorphous heterogeneous Ti/SiO catalyst in the presence of -butyl alcohol. The influence of some relevant process variables such as temperature and the hydrogen peroxide-to-double bond molar ratio on performance is examined. The highest yields of epoxidized olefins were obtained upon using a HO∶ substrate molar ratio of 1.1 ∶ 1. Higher ratios than this were not effective for speeding up the reaction. Under the experimental conditions employed in this work, no degradation of the oxirane ring was observed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Green Chemistry Royal Society of Chemistry

Abstract

We report a study of the epoxidation of soybean oil and soybean methyl esters with hydrogen peroxide in dilute solution (6 wt%) using an amorphous heterogeneous Ti/SiO catalyst in the presence of -butyl alcohol. The influence of some relevant process variables such as temperature and the hydrogen peroxide-to-double bond molar ratio on performance is examined. The highest yields of epoxidized olefins were obtained upon using a HO∶ substrate molar ratio of 1.1 ∶ 1. Higher ratios than this were not effective for speeding up the reaction. Under the experimental conditions employed in this work, no degradation of the oxirane ring was observed.
