摘　　要：以妥尔油脂肪酸和豆油脂肪酸为原料,在碘催化剂的作用下进行异构化反应,并与丙烯酸进行Diels-Alder反应生成C_(21)二元羧酸。粗产品通过分子蒸馏分离提纯得到C_(21)二元羧酸。该化合物具有优异的表面活性性能,其钠、钾、铵盐水溶性好,且在高浓度下依然能保持较低的粘度。With I2 as catalyst,linoleic acids in tall oil fatty acid or soy fatty acid were isomerized,and a C21 dicarboxylic acid was prepared from acrylic acid and isomerized linoleic acid by Diels-Alder reaction. The product C21 dicarboxylic acid could be obtained by molecular distillation separation. C21 dicarboxylic acid has perfect surface activity. Its sodium,potassium and ammonium soaps can dissolve in water easily,and keep low viscosity at high concentration.
