复合型铁钾盐催化合成乙酸异戊酯的研究

Study on Synthesis of Isoamyl Acetate by Composite Ferric Potassium Salt as Catalyst

以复合型铁钾盐为催化剂催化合成乙酸异戊酯,确定了冰乙酸与异戊醇的酯化合成条件,实验结果表明:n(酸)∶n(醇)=2.5∶1(异戊醇0.08 mol),催化剂用量为0.76 g,反应时间为2 h,带水剂环己烷为5 mL,酯化率可达92.8%。

Isoamyl acetate was synthesized from acetate and isoamyl using composite ferric postassium salt as catalyst. The restdts show that when n（aeetate） ： n（isoamyl） = 2.5： 1 ,dosage of the catalyst is 0.76 g, the reaction time is 2 h, water -carrying reagent eyelohexane is 5 mL, the esterifieation rate is up to 92.8%.
