摘要
在十二水合硫酸铁铵存在下由顺丁烯二酸酐和正丁醇制备了顺丁烯二酸二丁酸。在马来酸酐、正丁醇和十二水合硫酸铁铵的摩尔比为 1∶4∶0 .0 83 ,回流温度下反应 1 1 0~ 1 2 0分钟 ,酯收率可达 94 .7%。
Dibutyl maleate is prepared from maleic anhydride and n-butyl alcohol in the presence of ammonium ferric sulfate dodecahydrate. The yield of the ester can reach 94.7% under mole ratio of maleic anhydride,n-butyl alcohol and ammonium ferric sulfate dodecahydrate are 1∶4∶0.083,and reaction time of 110~120min at reflaxing temperature.$$$$
