Paragraph 0033; 0038; 0043; 0048; 0053; 0058, (2017/11/04)
The invention discloses a preparation method of 1,1,2,3-tetrachloropropene. The method comprises the steps of (1) reacting trichloromethane, 1,2-dichloroethylene and a first catalyst, cooling to room temperature after reaction is completed, adding water, carrying out vacuum rectification to obtain 1,1,2,3,3-pentachloropropane; (2) carrying out gas-phase catalytic dehydrochlorination reaction on the 1,1,2,3,3-pentachloropropane under the action of a second catalyst to obtain 1,2,3,3-tetrachloropropene; (3) carrying out gas-phase catalytic addition reaction on hydrogen chloride and the 1,2,3,3-tetrachloropropene under the action of a third catalyst to obtain 1,1,2,2,3-pentachloropropane; and (4) carrying out gas-phase catalytic dehydrochlorination reaction on the 1,1,2,2,3-pentachloropropane under the action of a fourth catalyst, collecting a reaction product and carrying out vacuum rectification to obtain the 1,1,2,3-tetrachloropropene. The preparation method is simple in process, available in raw materials, low in cost, high in yield, green and environment-friendly and is especially suitable for industrial production.

PROCESS FOR THE PRODUCTION OF CHLORINATED ALKANES
-
Paragraph 0037-0040, (2013/06/27)
Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the chlorination of a feedstream comprising one or more alkanes and/or alkenes with a catalyst system comprising one or more inorganic iodine salts and/or lower than conventional levels of elemental iodine and at least one Lewis acid. The processes are conducted in a nonaqueous media, and so, the one or more inorganic iodine salts are recoverable and/or reusable, in whole or in part.
