Study on Catalytic Synthesis of Butyl Butyrate in Ionic Liquid

Cui Yong-chun

Abstract

PTSA ionic liquid was made by microwave irradiation and synthesized butyl butyrate as catalyst.Orthogonal design method was employed to optimize condition of the reaction.The best conditions were described as following : PTSA is 15mL,the mole ratio of alcohol to acid is 1.4∶1.0,the reaction time is 2.5h.The esterification yield is 97.8%.The ionic liquid could be isolated from other matters and applied repetitively.
