Usage

General Description

Pentachloro(chloromethyl)benzene is a chemical compound consisting of a benzene ring with five chlorine atoms and one chloromethyl group attached. It is a chlorinated aromatic hydrocarbon and is commonly used as a pesticide and fungicide. This chemical is toxic and may cause skin and eye irritation, as well as respiratory and digestive issues. It is also considered to be a potential environmental hazard due to its persistence in the environment and potential to bioaccumulate in organisms. Pentachloro(chloromethyl)benzene is also a suspected human carcinogen and has been regulated and restricted in many countries due to its potential harmful effects on human health and the environment.

DESTRUCTIVE CHLORINATION OF ALKYLBENZENES ON HETEROGENEOUS CATALYSTS.

A study was made of the destructive chlorination of alkylbenzenes in the vapor phase on metal oxides and metal chlorides. This work shows that 380-400 degree C, 11-12 sec contact time, 0. 3-0. 8 mass % MoO//3 on alumina, 7-10% stoichiometric excess of chlorine, and 1:9 toluene/chlorine mole ratio were optimal for the chlorination of toluene to give C//6Cl//6 and CCl//4. The optimal conditions for the preparation of pentachlorobenzyl chloride were 295-320 degree C, 18-22 sec contact time, 1:6 toluene/chlorine mole ratio, and 4-8. 5 mass % MgCl//2 on KSK silica gel. The optimal yields of CCl//4 and C//6Cl//6 were 97. 4-98. 2 and 93. 8-96. 3 mole %, respectively, with 91-93 mole % conversion of chlorine.

Polyhalobenzylic disulfooxonium compounds

Polyhalobenzylic disulfooxonium compounds are produced by the reaction of aromatic methyl, halomethyl or hydroxymethyl substituents with sulfur trioxide. The disulfooxonium salts are readily converted to alcohols by hydrolysis to provide monomers for the production of fire resistant polymers and additives for polymers. Likewise, the disulfooxonium compounds of this invention present chemical intermediates for a wide range of useful products such as halogenated pesticides.
