Abstract: Carbon based naphthalenesulfonic acid was used as a catalyst in the synthesis of alkenyl succinic anhydride (ASA) from nonterminal olefin of C13~C14 and maleic anhydride. The catalytic activity and stability of the catalyst were evaluated quantitatively by gas chromatography. The results show that carbon based naphthalenesulfonic acid catalyst has high activity and good stability in the synthesis of ASA. When the activation temperature of catalyst is 250 ℃, the optimum conditions are as follows: reaction temperature 190 ℃, reaction time 4 h, weight ratio of catalyst to reactant 1∶100, molar ratio of nonterminal olefin to anhydride is 3∶1, and the weight percentage of antioxidant 2,6-di-tert-butyl-p-cresol is 0.5%. Under the above conditions, the yield of ASA can reach 59.6%.

摘要：   以Ｃ_１３－Ｃ_１４的内烯烃和顺丁烯二酸酐制备烯基琥珀酸酐为探针反应，利用碳基萘磺酸催化合成了烯基琥珀酸酐，考察了催化剂的催化活性和稳定性，利用气相色谱对产品的产率进行定量分析。结果表明：该催化剂在烯基琥珀酸酐的合成中具有较高的催化活性和良好的稳定性。在碳基萘磺酸催化剂的活化温度为２５０℃情况下，反应操作的最佳条件是：反应温度为１９０℃，反应时间为４ｈ，催化剂质量分数为１％，ｎ（内烯）∶ｎ（酸酐）＝３∶１，抗氧剂２，６－二叔丁基对甲酚的质量分数为０．５％。在最佳条件下，烯基琥珀酸酐的产率可达５９．６％。
