摘要

Abstract

The epoxidation of unsaturated fatty acid methyl esters(FAMEs)by peroxyacetic acid generated

in situ

from hydrogen peroxide and acetic acid was studied in the presence of SO

H-functional Brnsted acidic ionic liquid (IL)[C

HMIM

]

[HSO

]

as catalyst.The effects of hydrogen peroxide/ethylenic unsaturation ratio

acetic acid concentration

IL concentration

recycling of the IL catalyst

and temperature on the conversion to oxirane were studied.The kinetics and thermodynamics of unsaturated FAMEs epoxidation and the kinetics of oxirane cleavage of the epoxidized FAMEs by acetic acid were also studied.The conversion of ethylenic unsaturation group to oxirane

the reaction rate of the conversion to oxirane

and the rate of hydrolysis(oxirane cleavage)were higher by using the IL catalyst.
