| Abstract: | The synthesis of butyl acetate from n-butanol and acetic acid with nanosolid superacid SO2-4/ZrO2-Al2O3 as catalyst was studied.The influence factors of reaction were investigated.Results show that the appropriate condition are:molar ratio of n-butanol to acetic acid 1.5 ∶1,weight of catalyst 0.6 g,reaction time 3.0 h;water carrying agent 9 mL,reaction temperature 140 ℃.The yield of butyl acetate is about 96.5%. |
