以多种表面活性剂为催化剂,苯胺和邻苯二甲酸酐为原料,在水溶剂中合成N-苯基邻苯二甲酰亚胺,考察了反应时间,催化剂用量,胺酐比等因素对产物收率的影响。结果表明,采用阴离子表面活性剂十二烷基苯磺酸钠有最好的催化活性,当反应时间为5h,胺酐比为1.1∶1(mol),表面活性剂浓度2%(以溶剂质量计)时,收率可达到93.8%,且催化剂重复使用性好。 Aniline and phthalic anhydride were used as raw materials to synthesize N-phenylphthalimide with various surfactants as catalyst. The effects of reaction time, amount of catalyst, Effect of product yield. The results showed that the anionic surfactant sodium dodecyl benzene sulfonate has the best catalytic activity. When the reaction time is 5h, the ratio of amine to anhydride is 1.1:1 (mole), the concentration of surfactant is 2% Meter), the yield can reach 93.8%, and the catalyst has good reusability.
