The present invention describes the preparation of a tetrachloropropane such as pentachloropropane (such as 1,1) from a tetrachloropropane such as 1,1,1,3-tetrachloropropane in the presence of a polyvalent ruthenium compound including a pentavalent ruthenium compound such as antimony pentachloride. , 1,2,3-pentachloropropane) Chlorinated hydrocarbons. A method of preparing an olefin which is optionally chlorinated, such as tetrachloropropene, from a chlorinated alkane such as pentachloropropane in the presence of ferric chloride and a polyvalent hydrazine compound including a pentavalent hydrazine compound is also described. |
