Hydrodechlorination of a two-component mixture of chloroaromatic compounds in the presence of an unsupported sulfide catalyst

The effects of reaction time on the conversion of 2-chlorotoluene and heptene-1 and two-component systems were determined. The hydrodechlorination of 1,4-dichlorobenzene was accelerated in the presence of heptene-1. The high activity of an unsupported NiWS catalyst was shown in the hydrodechlorination and hydrogenation of a 1,4-dichlorobenzene–2-chlorotoluene (heptene-1) mixture.
