以β-环糊精为催化剂,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,溶剂用量等因素对产物收率的影响。结果表明,β-环糊精有着很好的催化活性,当反应时间为5h,胺酐比为1.3∶1(mol),β-环糊精浓度1%(以溶剂质量计)时,在30mL加入少量盐酸的水溶剂中,收率可达到88.7%,且催化剂重复使用性好。 Using β-cyclodextrin as catalyst, aniline and phthalic anhydride as raw materials, N-phenylphthalimide was synthesized in water solvent. The effects of reaction time, catalyst amount, amine-anhydride ratio, solvent amount And other factors on the yield of the product. The results showed that β-cyclodextrin had a good catalytic activity. When the reaction time was 5h, the ratio of amine to anhydride was 1.3:1 (mol) and the concentration of β-cyclodextrin was 1% (based on the mass of the solvent) Add a small amount of hydrochloric acid in water solvent, the yield can reach 88.7%, and the catalyst reusability.
