Abstract

A process is provided for the stabilization of polychlorinated alkanes against dehydrochlorination. The process comprises adding a phenol compound to a polychlorinated alkane such that the dehydrochlorination of the polychlorinated alkane is suppressed when heated in the presence of iron(III). In a preferred embodiment, the process comprises the prevention or reduction of dehydrochlorination of 1,1,1,3,3-pentachloropropane when heated in the presence of iron(III) contamination by the addition of monomethyl ether hydroquinone. In another embodiment, the long term storage stability of polychlorinated alkanes against dehydrochlorination is improved due to the addition of a phenol compound.
