摘　　要：利用微波辐射技术,以硫酸氢钠为催化剂,快速合成了已酸乙酯,并考察了影响反应的因素。实验结果表明:微波辐射功率560 W;辐射时间8 m in;醇酸物质的量比2∶1;硫酸氢钠1.0 g(已酸0.2 mol);酯化率可达96.2%。Ethyl caproate was synthesized fast by microwave radiation, with sodium bisulfate as catalyst, and factors affecting reaction were investigated. Experimental result indicated that the optimal condition was irradiation power as 560w; irradiation of 8 min, mole ratio of acid to alcohol as 1：2, 1.0 g of catalyst （ when haxanoic acid was 0.2mol） with yield of 96.2%.
