| Abstract: | With pmpionic acid and iso-amyl alcohol as raw material,p-Toluene sulfonic acid as catalyst,iso- amyl propionate was synthesized directly under normal pressure and microwave irradiation.The most suitable reaction conditions were 0.25 g p-Toluene sulfonic acid,0.2 tool propionic acid,0.6 tool iso-amyl alcohol, and the microwave irradiation time were 2 rain with the power of 750 w.The conversion rate of propionie acid was 96.6% under the above reaction conditions.Compared with conventional heating method,microwave irra- diation has such advantages as faster reactions,higher yields. |
