Abstract
A process for the production of 1,1,2-trichloro-2-methylpropane comprises reacting 1-chloro-2-methylpropene with sulfuryl chloride. This reaction takes place preferably under the effect of light, especially UV light and/or in the presence of an aldehyde as the catalyst. The starting material contains less than 10 ppm of N-containing compounds conventionally employed to stabilize it.

A process for the production of 1,1,2-trichloro-2-methylpropane, comprising reacting 1-chloro-2-methylpropene with sulfuryl chloride wherein the 1-chloro-2-methylpropene contains less than about 10 ppm of a stabilizer therefor which stabilizer in greater amounts would interfere with said reaction whereby 1,1,2-trichloro-2-methylpropane is produced essentially selectively and in high yield.
