Epoxidation of Vegetable Oils Catalyzed by Heteropoly Acids

Department of Chemistry, Northeast Normal University, Changchun 130024

Received Date: 5 May 1997
Revised Date: 11 August 1997

Some heteropoly acids were used as catalyst for epoxidation of soybean oil and corn oil by hydrogen peroxide and formic acid. Among them the CPW, i.e. [(C₅H₅)N-(CH₂)₁₅CH₃]₃PW₁₂O₄₀ was found to be the most active one. The epoxidized soybean oil and corn oil have epoxy value of 6.6% and 6.4%, respectively, with iodine value less than 6 g(I₂)/100 g.
