An efficient esterification of succinic anhydride (SA) to dimethyl succinate (DMS) using ZnO in methanol was investigated for the first time. ZnO is commercial, low cost, noncorrosive and environmentally friendly metallic oxide and can promote remarkably the production of DMS from SA in excellent yields with high selectivity. The highest yield of DMS of 100% was achieved at the temperature of 140 °C for 10 h. The results indicated that reaction temperature and time had significant influences on the yield of DMS. Mechanism study found that ZnO was first dissolved to form a Zn species, and then redeposited to ZnO during the reaction, which was crucial for SA conversion. The redeposited ZnO could be reused at least 4 times without the loss of the activity. Moreover, the reaction of ethanol and SA was also effective to give excellent yield at the optimal conditions. The present study demonstrates a promising greener way for the synthesis of DMS from biomass-derived SA.

通过甲醇中ZnO上琥珀酸酐的酯化反应轻松合成琥珀酸二甲酯

首次研究了在甲醇中使用ZnO将琥珀酸酐（SA）有效酯化为琥珀酸二甲酯（DMS）。ZnO是商业，低成本，无腐蚀且对环境友好的金属氧化物，可以显着促进以高收率和高选择性从SA生产DMS。在140°C的温度下10小时，DMS的最高收率为100％。结果表明，反应温度和时间对DMS的收率有显着影响。机理研究发现，ZnO首先溶解形成Zn物种，然后在反应过程中重新沉积到ZnO中，这对于SA转化至关重要。重新沉积的ZnO可以重复使用至少4次，而不会损失活性。而且，在最佳条件下，乙醇和SA的反应也能有效地获得优异的收率。本研究证明了从生物质衍生的SA合成DMS的绿色方法很有希望。
