| Abstract: | 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%. |
