摘要

Abstract

A new reactive and extractive distillation process with ionic liquids as entrainer and catalyst (RED-IL) was proposed to produce methanol and n-butyl acetate by transesterification reaction of methyl acetate with n-butanol. The RED-IL process was simulated via a rigorous model

and high purity products of methanol and n-butyl acetate can be obtained in such a process. The effects of reflux ratio

feed mode

holdup

feed location

en-trainer ratio and catalyst concentration on RED-IL process were investigated. The conversion of methyl acetate and purities of products increase with the holdup in column

entrainer ratio and catalyst content. An optimal reflux ratio exists in RED-IL process. Comparing to the mixed-feed mode

the segregated-feed mode is more effective

in which the optimal feed locations of reactants exist.
