摘要
制备了甲磺酸铜催化剂,对其结构进行了IR和热重分析,并用于催化草酸和异戊醇的酯化反应。结果表明,甲磺酸铜具有催化活性高、稳定,易分离,重复使用性能优良,对环境友好的特点。最佳酯化工艺条件为:n(异戊醇):n(草酸)=2．8:1,w(甲磺酸铜)=0．3％,以过量的异戊醇为带水剂,回流反应2．0 h,酯化率可达到96．8％。
Copper methanesulfonate was synthesized, characterized by IR and TGA and used as catalyst in the esterification of oxalic acid with isoamyl alcohol. The results showed that copper methanesulfonate had high catalytic activity and good stability, and could be simply separated and reused after reaction. It is an environmental friendly catalyst. Various factors that affected the esterification were investigated. Under the optimal conditions, i. e. , 2.8 molar ratio of isoamyl alcohol to oxalic acid, 0.3% catalyst, 2.0 h reaction time, the esterification degree of diisopentyl oxalate was up to 96.8%.
