1) azeotrope feed
From this point of view, in this thesis, the two kinds of catalysts-- the oxidativate carbonylation catalyst and hydrolysis catalyst were investigated to study the catalyst to the synthesis of DMC by methanol/DME co-feeding.

4) azeotropic [ə,zi:ə'trɔpik]
The homogeneous batch distillation and hetegeneous azeotropic batch distillation were studied for separating dimethylbenzene and butylacetate from the industrial waste solvents in this article.
Reaction temperature is determined by co-boiling point while using organic solvent.
It's quite difficult to purify the substance co-boiling with water.
6) azeotrope [英]['eizi:ə,trəup] [美]['eziə,trop]
A computer-aided molecular design(CAMD)method based on genetic algorithm was proposed to design extractant molecule for extractive distillation of 1-butanol-butyl acetate azeotrope system.
Objective:Improve aleotropic crystallizing condition of penicilling and increase sylvite yield Method Azeotrope tower is added to W type bottom,Improved vacuum—degree and adjusted agitating rolling figure.
The variation of binary azeotropes with pressure were studied.
