| 摘 要： | 以苯乙烯／二乙烯苯为原料，合成了DZH型树脂催化剂。通过静态/动态等测试方法，研究了树脂催化剂的热稳定性，优化了催化剂合成的工艺条件。制备的DZH型树脂催化剂用于顺丁烯二酸酐酯化反应，在反应温度90～110 ℃、反应压力0.6 MPa、m(甲醇)∶m(顺丁烯二酸酐)1.4、顺丁烯二酸酐空速0.74 h－1条件下，顺丁烯二酸酐转化率≥99.6%，马来酸二甲酯收率≥98.6%。

| Abstract: | A resin catalyst (DZH) for maleic anhydride esterification was prepared and its thermal stability studied using static/dynamic test methods. Process conditions for synthesis of the catalyst were optimized. Maleic anhydride conversion of 99.6% and dimethyl maleate yield of 98.6% were obtained over DZH resin catalyst under the following condition: 90～110 ℃,0.6 MPa, LHSV=0.74 h－1, m(methanol)∶m(maleic anhydride) =1.4∶1. |

| Keywords: | maleic anhydride esterification resin catalysts dimethyl maleate |
