摘　　要：以丝瓜络为起始碳源,浓硫酸为磺酸化试剂,制备了丝瓜络基炭磺酸,以该炭磺酸为催化剂,以双氧水为氧源,甲酸为活性氧载体,采用无溶剂法就地合成了环氧大豆油。正交优化实验结果表明:双氧水用量为24 ml、甲酸用量为3.2 ml、催化剂用量为0.7 g、反应温度为65℃、反应时间为3 h,所得产品环氧值>6.5%,产品色泽透明。与自制的稀土固体超强酸对比催化实验结果表明:丝瓜络炭磺酸催化剂更加高效、稳定,可以用来改进传统环氧大豆油的制备工艺。The char sulfonic acid catalyst was prepared by using luffa cylindrica as raw materials and concentrated sulfuric acid as sulfonating reagent. Then, epoxidized soybean oil（ESO） was synthesized using hydrogen peroxide as the oxygen source, formic acid as the active oxygen carrier, in the presence of above catalyst by solvent free process. The orthogonal experiment result shows that the optimal reaction conditions are using 24 ml hydrogen peroxide 24 ml, 3.2 ml formic acid and 0.7 g catalyst at 65℃ for 3 h. The epoxy value of ESO 6.5%, the ESO product color is transparent. Compared to the self-made rare earth solid superacid, the char sulfuric acid catalyst made from luffa cylindrica is more efficient and stable, and can be used to improve the traditional preparation process of epoxy soybean oil.
