| Abstract: | By using sodium hydrogen sulfate as the catalyst, butyric acid and amyl alcohol reacted to form amyl butyrate. The optimum conditions using 0.1 mol of butyric acid are as following: molar ratio of amyl alcohol to butyric acid is 1.2, mass of catalyst is 0.2 g, toluene is 5 ml and reaction time is 30 min. The esterification yield for butyric acid is about 99.3 % . Without toluene, the esterification rate of synthetic food additives amyl butyrate is about 99.7 % . |
