摘　　要：以非酸催化剂为催化剂,采用无溶剂法工艺合成环氧大豆油,进行实验室小试,优化工艺条件为：大豆油∶H2O2∶乙酸为1∶（0.40～0.45）∶（0.65～0.70）（W/W/W）,催化剂用量5%～6%（以大豆油计）,相转移稳定剂用量0.2%～0.3%（以大豆油计）,反应温度70～75℃。根据小试优化的工艺条件确定了环氧大豆油的生产工艺,分别采用新鲜乙酸和乙酰柠檬酸三丁酯回收乙酸进行了中试,所得产品质量能达到一级品和合格品要求。With the catalyst of non-acid catalyst,the solvent-free synthesis process of epoxy soybean oil was tested in laboratory.The optimum conditions were as follows： soybean oil ∶H2O2∶acetic acid = 1∶（0.40 ～ 0.45）∶（0.65 ～0.70）（W/W/W）,catalyst dosage 5% ～ 6%（basis of soybean oil）,transform stabilizer 0.2% ～ 0.3%（basis of soybean oil）,reaction temperature 70 ～ 75 ℃.According to the process condition was optimized production process of epoxy soybean oil were determined.Using fresh acetic acid and acetic acid recycled of tributyl O-acetylcitrate the pilotscale experiments were studied,the product quality can reach the first class products and qualified products requirements.
