| Abstract: | Using ferric sulphate and potassium persulfate as mix catalyst, propionic acid and n butyl alcohol as material, the synthesis of butyl propionate was studied. The influence factors, such as amount of catalyst, ratio of n butyl alcohol and propionic acid, and the reaction time, were also studied. The results showed that under the optimum conditions, the yield of esterification was up to 98.5%. |
