Abstract

Halohydrocarbons comprising at least 3 carbon atoms are obtained by reaction between a haloalkane and a haloolefin, in the substantial absence of nitrile, and by introducing the reactants in a molar ratio between the haloalkane and the haloolefin of less than 2. 1,1,1,3,3-Pentachloropropane can thus be obtained in good voluminal yield.
