| Abstract: | The synthesis of n-butyl lactate by using ferric sulphate and potassium persulfate as mix catalytic, lacticacid and n-butylalcohol as material ,was studied.The influence factors, such as amount of catalyst ,ratio of lacticacid and n-butylalcohol ,and reaction time ,were also studied. The results showed that under the optimum conditions, the yield of esterification was up to 93.2% . |
| Keywords: | ferric sulphate and potassium persulfate catalytic esterification n-butyl lactate |
