磺酸功能化离子液体催化合成乙酸正丁酯
Synthesis of n-butyl acetate by sulfonic acid functionalized ionic liquid
摘要
Abstract
In order to meet the requirements of green chemistry,solving the problems of traditional esterification catalyst,equipment corrosion,side reactions and so on,with morpholine as raw material,sulfonic acid functionalized ionic liquids,like 1-(3-sulfonic group) propyl-3-methyl morpholino methyl sulfonate were successfully synthesized.The structures and properties were characterized with the Fourier transform infrared spectrometer and nuclear magnetic resonance spectrometer.The catalytic performance of the catalyst was investigated in the application of esterification reaction of acetic acid with butyl alcohol.The yield of n-Butyl acetate was up to 96.44％ under the optimized conditions of n(CH3COOH)∶ n(C4H9OH) =1.2∶ 1,the mass of catalyst [Mor-C3SO3H] MeSO3 was 5％ of the quality of butyl alcohol,the mass of water carrying agent was 20％ of the quality of butyl alcohol,temperature was 95 ℃,and reaction time was 5 h.The catalysts also could be recycled for 7 times,and the catalytic activity still kept more than 94％.关键词
