Iron(Ⅲ) chloride catalyzed deoxygenative chlorination of alcohols;

Study on Chlorination of Benzyl Alcohol

At different temperatures the ring-chlorination of p-chlorotoluene has been studied with FeCl_3, SbCl_3 or clay as catalyst.

In this paper, a new method, Gas Chromatography(GC)-Relative Density(RD) coupling method, was studied for alpha-Chloro reaction depth on-line monitoring.

The mechanism and kinetics of dechlorination were studied in order to reduce dechlorination.

At ambient temperature and pressure, the natural and the enhanced reductive dechlorination of 4-chlorophenol (4-CP) in soils with zero-valent iron (ZVI) were investigated in the laboratory with isothermal incubation and gas chromatography mass spectrometry (GC-MS) as the primary analytical method.

In this laboratory study,the effects of zero valent iron(ZVI),noble metals modified ZVI,and other reaction controlling factors on the reductive dechlorination of hexachloroethane(HCE) were investigated under conditions of isothermal incubation.

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.
