Abstract
PURPOSE: To prepare hexachloroethane at low cost in simple process, by the chlorintion of tetrachloroethylene using azobisnitriles as a catalyst.
CONSTITUTION: In the preparation of hexachloroethane by chlorinating tetrachloroethylene, the chlorination reaction is carried out above 50W60°C, adding 0.001W 1.0 wt.% (preferably 0.01W0.1 wt.%), based on the chlorination solvent, of azobisnitriles of formula (R1WR4 are alkyl or cycloalkyl; pref. azobisisobutyro- nitrile ) as a catalyst. Chlorinated hydrocarbons are preferable as the solvent, and particularly CCl4 or tetrachloroethylene which is a raw material of the process, is suitable. Ni, glass lining, etc. is preferable as a material of the reactor to prevent the contamination of the desired compound with metallic chlorides.
