Abstract: The epoxidized soybean oil methyl ester was prepared by a non⁃solvent method under a mild condition using molybdenum polyoxometalates as catalysts.The epoxy soybean oil methyl ester with an acid value of 0.58 mg (KOH)/g and an epoxy value of 3.73% could be obtained using a H2O2:C=C of substrate molar ratio of 1.5 with adding 1.5% catalyst [(C2H5)4N]4Mo8O26 when 20 g soybean oil methyl ester was epoxidized at 55 ℃ for 5.0 h. The method has the advantages that the catalyst is easy to be separated and the post⁃treatment is simple. Moreover, the product does not contain inorganic acid, which avoids the influence of inorganic acid on the analysis and treatment of product.
