摘　　要：通过改进磷酸三异辛酯的传统合成方法,以三氯氧磷和异辛醇为原料,采用一步法合成磷酸三异辛酯。通过实验确定最佳工艺条件:n(三氯氧磷)∶n(异辛醇)为1∶3.5,选择四氯化钛作为催化剂,用量为1%,异辛醇的滴加温度为0~10℃,滴加完成后于15~20℃保温1 h,升温至75~80℃保温3 h,反应压力为0.09~0.1 MPa,产品收率90%,含量>99.0%,蒸馏残液进行了绿色化处理。This paper introduces an improved method based on the traditional synthesis method of triisooctyl phosphate.This new method uses phosphorus oxychloride and isooctanol as raw materials to synthesize triisooctyl phosphate using a one-step method.The optimal process conditions were determined through experiments:n(phosphorus oxychloride)∶n(isooctanol)=1∶3.5,dropwise addition temperature:0~10℃,two-stage insulation temperature of 15~20℃/75~80℃,vacuum degree:0.09~0.10 MPa,product yield of 90%,content>99.0%,and the distillation residue was treated with green treatment.
