Analysis and Evaluation of Oxychlorination Reactor Fluidization Quality;

Kinetic determination of ethylene oxychlorination reaction

The structure, process and security of ethylene oxychlorination reaction units, which were made by Mitsui Toatsu Co.

Intelligent control system for the mole ratio of the raw materials components in oxychlorination reactor;

Through analyzing reasons for the corrosion of cyclone separator for oxychlorination reactors,the material selection scheme and the installation improvement measures for cyclone separator were put forward.

Based on the analysis, material selection of oxygen chloride reactor was discussed from theory and practice in accordance with corrosion resistance of material.

It was found that there existed pit corrosion,intergrandular corrosion and stress corrosion on the inner surface of the oxygen chloride reactor in the polyvinyl chloride plant.

o-Chlorobenzaldehyde,which was a fine chemical product widely used in pesticide industry,pharmaceutical industry and dyeing industry,was prepared from the residual liquid generated in the restification in the production of o-chlorobenzyl chloride by chlorination reaction,hydrolysis reaction and distillation.

6-Chloro-5,12-naphthacenequinone was synthesized from 2-(1-hydroxy-2-naphthyl)carbonylbenzoic acid by chlorination reaction using a mixture of phosphorus pentachloride and phosphorus oxychloride as a chlorating agent and then by ring-closing reaction using sulfuric acid as a dehydrating agent.

Advances on molecule-bolt selective monochlorination and reaction-separation coupling techniques for chlorination reaction in the world were introduced, and the control technology which achieved high selectivity was showed.
