摘要

Abstract

The acid-functionalized ionic liquid ([HSO

Pmim

]

HSO

) was synthesized by a two-step method. Nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscopy (FT-IR) showthat the synthesis method is feasible and high purity of ionic liquid can be obtained. Using [HSO

Pmim

]

HSO

as the catalyst

we studied the reaction kinetics of synthesizing sec-butyl alcohol from sec-butyl acetate and methanol by transesterification in a high-pressure batch reactor. The effects of temperature

initial molar ratio of methanol to ester

and catalyst concentration on the conversion of sec-butyl acetate were studied. Based on its possible reaction mechanism

a homogeneous kineticmodelwas established. The results showthat the reaction heat ΔHis 10.94 × 10

J·mol

-1

so the reaction is an endothermic reaction. The activation energies E

and E

are 60.38 × 10

and 49.44 × 10

J·mol

-1

respectively.
