Study on microwave-assisted regeneration of hypercrosslinked polymeric adsorbent adsorbing o-chlorophenol;

Sorption properties of phenol,o-chlorophenol,2,4-dichlorophenol on four kinds of suspended particles sampled from Changjiang Estuary and Hangzhou Bay were investigated.

The preparation of o-chlorobenzaldehyde from the residual liquid generated in the production of o-chlorobenzyl chloride;

According to the main problem of current synthesis of o-chlorobenzyl chloride in our country,effective improvement was studied to increase the reaction conversion to 60% by use of a new catalyst CHJ-3.

Taking o-cholorotoluene as raw material,the factors influencing the photochlorination synthesis of the o-chlorobenzyl chloride were investigated.

MOCA is prepared with o-chloroaniline and paraformaldehyde as materials.

The cheap available starting material,O-chloroaniline,reacted with trichloroacetaldehyde monohydrate and hydroxylamine hydrochloride to produe N-(2-chlorophenyl)-2-(hydroxyimino) acetamide;which was treated with concentrated sulfuric acid to obtained 3-chlorolisatin,then 3-chlorolisatin was oxidized by hydrogen peroxide to afford 2-amino-3-chlorobenzoic acid.

A series of titania-supported nickel catalysts with different Ni loadings (10%～40%) were prepared by the incipient impregnation method and applied in the hydrogenation of o-chloronitrobenzene to o-chloroaniline.
