固体超强酸作甲酸甲酯水解制甲酸的催化剂．研究催化剂、进料速度、反应温度对甲酸甲酯水解转化率和对甲酸出口浓度的影响．当原料水与酯的摩尔比为１、反应温度１００℃、原料与催化剂的接触时间为１６ｍｉｎ．时，甲酸甲酯的转化率为２４．６％（甲酸的出口浓度达１４．５％）． Solid super acid as methyl formate hydrolysis of formic acid catalyst. The effects of catalyst, feed rate, reaction temperature on the conversion of methyl formate and the concentration of formic acid were investigated. When the raw material water and ester molar ratio of 1, the reaction temperature was 100 ℃, the contact time of the feedstock and the catalyst was 16min. , Methyl formate conversion was 24.6% (formic acid outlet concentration of 14.5%).
