Production of Benzyl Chloride and Benzal Chloride and of Certain Homologues and Substitution Products of these Compounds.

摘要

Benzyl chloride, benzal chloride, and similar side-chain chlor-substituted aromatic hydrocarbons are prepared by treating toluene or its homologues at a low temperature with aqueous hypochlorous acid (hypochlorite and acid). The process can also be applied to the treatment of the chlor-derivatives of these hydrocarbons containing one or two chlorine atoms in the nucleus or one chlorine atom in the side chain, e.g. monochlortoluenes, 2 : 4-dichlortoluene, or benzyl chloride. Examples are given of the preparation of benzyl chloride from toluene and benzal chloride from benzyl chloride; m-xylene gives m-tolyl chloride and m-tolal chloride.
