| 摘 要： | Methane-sulfonate of copper, cobalt, zinc, lanthanide, praseodymium and neodymium are synthesized and characterized by FTIR and TGA. Methane-sulfonates are used as the catalysts in the esterification of chloroacetic acid with isopropanol. Catalytic activity of methane-sulfonates is studied and compared with other Lewis acids. Under the condition of 1.2/1 molar ratio of isopropanol to chloroacetic acid, 1% catalyst (molar percent of chloroacetic acid), 2.5h reaction time, 80～85℃ temperature and benzene as water-carrying agent. The experi-mental results showed that catalytic activity of Lanthanide methane-sulfonate was the best, the yield of isopropyl chloroacetate reaches 88.7%. Copper methane-sulfonate can be reused for three times without distinct loss of catalytic activity.
