摘 要: 制备固体超强酸SO4 2 - /Fe2 O3,并测定其红外光谱。以乙酸和正丁醇为反应物、固体超强酸SO4 2 - /Fe2 O3为催化剂 ,进行合成乙酸丁酯的研究。实验结果表明 ,固体超强酸SO4 2 - /Fe2 O3在合成乙酸丁酯反应中的催化活性与浓硫酸相当 ,用 0 1mol正丁醇与 0 2mol乙酸反应 ,催化剂用量 0 3g ,回流时间 90min ,乙酸丁酯收率为 63 8%。 The solid superacid SO 4 2- /Fe 2O 3 was prepared and IR spectrum of sample was determined.The synthesis of butyl acetate with butyl alcohol and acetic acid as reactants and solid superacid SO 4 2- /Fe 2O 3 as catalyst had been studied.The results showed that catalytic activity of SO 4 2- /Fe 2O 3 solid superacid is as good as sulfuric acid in the reaction of synthesis of butyl acetate; with catalyst 0.3 g and reaction time 90 min (weight of butyl alcohol 0 1 mol and acetic acid 0 2 mol),the yield of butyl acetate was 63 8%
