摘　　要：利用微波辐射技术,以硫酸氢钠为催化剂,快速合成了丙酸异戊酯,并考察了影响反应的因素。实验结果表明:微波辐射功率420W;辐射时间10min;醇酸物质量的比1．3:1．0;硫酸氢钠0．8g(丙酸 0．2mol);酯化率可达97．8％。By Using the technique of microwave radiation, under the catalyst of sodium hydrogen sulfate, isoamyl propionate can be. synthesized fast, The factors of the influencing reaction were investigated. Experimental results indicative the best reacting condition was： the power of microwave is 420w; the time of microwave is 10 rain; the mole ratio of acid to alcohol is 1.3： 1.0; the dose of catalyst is 0.8g （propionic acid 0.2mol）, the esterification yield is 97.8%.
