摘要
合成了甲烷磺酸锌、苯磺酸锌和对甲苯磺酸锌,并用热重分析仪和傅立叶转换红外光谱仪进行表征,它们在催化氯乙酸与醇反应中表现出较好的催化性能。在催化氯乙酸与异丙醇的反应中,甲烷磺酸锌的催化活性高于多种Lewis酸的催化活性;3种磺酸锌盐在连续8次的重复实验中表现出良好的重复使用性能。
Zinc methanesulfonate, zinc benzenesulfonate and zinc p-toluenesulfonate are prepared and characterized by TG and FTIR. They all exhibit high catalytic activities in many esterifications of alcohols with chloroacetic acid. In the esterification of isopropanol with chloroacetic acid, the catalytic activity of zinc methanesulfonate is higher than that of many other catalysts, zinc methanesulfonate, zinc benzenesulfonate and zinc p-toluenesulfonate all exhibit excellent reusabilities during the continual 8 recycling examinations.
