Synthesis and characterization of methane sulfonates and their catalytic activities for esterification

WANG Min, JIANG Heng, GONG Hong, WANG Rui (Institute of Petrochemical Engineering, Liaoning University of Petroleum & Chemical Technology, Liaoning Fushun 113001, China)  
Methane sulfonates of magnesium, aluminum, calcium, ferrous iron, cobalt, nickel, copper, zinc, barium, lanthanide, cerous cerium, praseodymium and neodymium were synthesized and characterized by TGA and FTIR. Catalytic activity of the methanesulfonates was studied and compared with other Lewis acids under the following condition : n-butanol-to-acetic-acid molar ratio=1.1/1, catalyst loading=0.25% (molar percentage of acetic acid), reaction time 2.5 h, 80-85 ℃ and 2.5 ml cyclohexane as water-carrying agent. The experimental results showed that methanesulfonates of lanthanide, copper, calcium exhibited the highest catalytic activity , with butyl acetate yield of over 90.0%. Methanesulfonate of copper, calcium, zinc can be reused by simple phase-separation without remarkable loss of catalytic activity.
