Abstract

[HSO_3-pmim]HSO_4 acid ionic liquid was prepared to synthesize n-butyl propionate whit it as catalyst.The catalyst activity and the different reaction condition influencing on the esterification were discussed.The results showed that the ionic liquid is good acetate of reaction. The optimized condition are follow:[HSO_3-pmim]HSO_4 is 6mL,the mole ratio of alcohol to acid is 1.5:1.0,the reaction time is 1.5h.The esterification yield is 96.3%.The ionic liquid could be isolated from other matters and repetition use.
