摘要
以对甲苯磺酸(PTSA)为催化剂运用微波辐射技术合成庚酸乙酯。其适宜的工艺条件为:酸醇物质的量比为1∶2.0,辐射时间5 min,辐射功率240 W,催化剂用量为2%(质量分数),产率可达89.6%以上。该条件下的反应速率是常规加热条件的30倍。
Ethyl heptanoate was synthesized by microwave irradiation and p-tolucnesulfonic acid as catalyst. The optimum technical conditions were as follows:molar ratio of heotanoie acid to ethyl alcohol is 1 : 2.0, irradiation time .is 5 min, microwave power 240 W, amount of catalyst is 2% and the yield is more than 89.6%. The reaction is 30 times faster under microwave irradiation than with conventional Key words: microwave irradiation; ethyl heptanoate ; p-toluenesulfonic acid heating
