The homogeneous batch distillation and hetegeneous azeotropic batch distillation were studied for separating dimethylbenzene and butylacetate from the industrial waste solvents in this article.

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.

Thinking about Azeotropy of the Turpentine Oil and Alcohol;

A series of working fluids were judged for azeotropy,for which the azeotropic points were predicted and compared with the literature value.

Improving the rate of return on sodium salt azeotropism crystallization by means of improving equipment;

The azeotropism-fractionation process for recovering formic acid from acid wastewater in cyclohexanol/ cyclohexanone production was studied,and the feasible kind and dosage of entrainment reagent for was determined.

Reaction temperature is determined by co-boiling point while using organic solvent.

It's quite difficult to purify the substance co-boiling with water.
