| Abstract: | In this study,isopentyl lactate was synthesized through refluxing,which is under the condition that 0.1mol lactic acid,the certain amount of isoamyl alcohol and ferric chloride hexahydrate.In order to find the best match,we studied the influence of the amount of catalyst and alcohol on this reaction.And using fourier transform infrared spectroscopy,we characterized the structure and properties of the product.The results showed that the yield of the ester is 79.3% when the molar ratio of lactic acid,isoamyl alcohol,and ferric chloride hexahydrate is 1∶2∶0.027. |
