PROCESSES FOR PREPARING PENTACHLOROPROPANE AND TETRACHLOROPROPENE FROM DICHLOROPROPENE
-
Paragraph 0090, (2022/04/03)
A processes for preparing 1,1,2,3-tetrachloropropene, 2,3,3,3-tetrachloropropene, or a mixture thereof from 1,3-dichloropropene. The process may include a two successive chlorination and dehydrochlorination reactions. In a first chlorination reaction 1,3-dichloropropene is reacted with a chlorination agent to form a first chlorination reaction product including 1,1,2,3-tetrachloropropane. This first chlorination reaction product is reacted with a dehydrochlorination reagent in a first dehydrochlorination reaction to form a first dehydrochlorination reaction product including a trichloropropene. The trichloropropene containing reaction product is reacted with a chlorination agent in a second chlorination reaction to form a second chlorination reaction product including at least one of 1,1,1,2,3-pentachloropropane or 1,1,2,2,3-pentachloropropane. This reaction product is reacted with a dehydrochlorination reagent in a second dehydrochlorination reaction to form a second dehydrochlorination reaction product having 1,1,2,3-tetrachloropropene or a 2,3,3,3-tetrachloropropene.
PROCESS FOR THE PRODUCTION OF CHLORINATED PROPANES AND/OR PROPENES
-
Paragraph 0078, (2013/06/05)
Processes for the production of chlorinated propanes and/or propenes are provided. The present processes make use of methylacetylene, a by-product in the production of ethylene and/or propylene, as a low cost starting material, alone or in combination with propadiene, propene and/or propane. In the latter embodiments, the processes may also be utilized to provide a substantially pure stream of propane.
