THE CHLORINATION OF ETHYLENE DICHLORIDE

Ug E. GALITZENSTEIN (the Ltc) and C. \VOOLF

The chlorination of ethylene dichloridc to form mainly I : I : 2trichloroethanc has hecn investigated. Various catalysts have been tried, but with most of those described in the literature, e . ~. antimony chloride, the reaction is slow in the abscnce of light ; In the presence of sunlight substitution is rapid. The use of aluminium chloride leads to the formation of tetrachlorocthanes.

Smooth chlorination to trichlorocthanc is also possible by thc use of sulphuryl chloride, with bcnzoyl peroxide as catalyst ; the bulk of thc sulphuryl chloride is reco\wiablc with thc aid of activated charcoal.

## Abstract Several H‐zeolites (H‐Y, H‐ZSM‐5 and H‐MOR) were investigated for the catalytic combustion of chlorinated ethylenes, namely 1,1‐dichloroethylene and trichloroethylene. Conversion was inversely related to the chlorine content of the feed molecule. H‐ZSM‐5 zeolite was the most active cata
