摘要: 以钼多金属氧酸盐为催化剂,采用非溶剂法,在温和条件下制备环氧大豆油甲酯。在大豆油甲酯质量为20 g、过氧化氢与C=C物质的量比为1.5、催化剂[(C2H5)4N]4Mo8O26摩尔分数为1.50%、反应温度为55 ℃、反应时间为5.0 h的条件下,获得酸值为0.58 mg(KOH)/g、环氧值为3.73%的环氧大豆油甲酯。该方法催化剂易分离,后处理简便、快捷,产物不含无机酸,避免了无机酸对产品性质分析处理带来的影响。

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.

Key words: Soybean oil methyl ester, Epoxidation, Epoxidized soybean oil methyl ester, Plasticizer
