摘要

摘要: 采用对甲苯磺酸和可溶性淀粉混合物部分炭化制备新型碳基固体酸催化剂，研究了m（对甲苯磺酸）∶m（可溶性淀粉）、炭化温度和炭化时间对催化剂催化合成1，4-丁二醇双琥珀酸二异辛酯的影响，用SEM、XRD、红外光谱、元素分析等对催化剂进行了表征。结果表明，在m（对甲苯磺酸）∶m（可溶性淀粉）=1.0∶2.0、炭化温度200℃、炭化时间8 h的条件下，得到碳基固体酸的催化活性最高，在180℃下反应1.5 h可达到规定的酯化率，催化剂重复使用5次后，酯化率仍能达到93%以上，另外该催化剂具有良好的热稳定性。

Abstract: Carbon-based solid acids were prepared by coking mixtures of p-toluene sulfonic acid and soluble starch with different ratios at different temperatures. The effects of the p-toluene sulfonic acid/soluble starch mass ratio, coking temperature and time on their catalytic activities in the esterification reaction of maleic anhydride with ethylene glycol were investigated. Results indicated that the activity of the acid was the highest when amixture with the mass ratio of 0.5 was coked at 200℃ for 8 h. The activity remained high after the solid acid had been used 5 times.
