| Abstract: | The synthesis of dibutyl maleate with butyl alcohol and maleic acid as reactants and amidosulphonic acid as catalyst has been studied. The influencing factors of reaction were investigated. The results showed thai the appropriate conditions should be: weight of catalyst was 0. 5 g (weight of maleic acid 0. 05 mol) ; molar ratio of butyl alcohol to maleic acid was 3:1; reaction time was 1.5 h; the water taking reagent (toluene) was 5 mL. The yield of dibutyl maleate was about 96. 8%. |
