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 0062-0065, (2013/06/05)
Processes for the production of chlorinated propenes are provided wherein the feedstream comprises 1,2-dichlropropane. The present processes make use of at least one reactor twice, i.e., at least two reactions occur in the same reactor. Cost and time savings are thus provided. Additional savings can be achieved by conducting more than two chlorination reactions, or all chlorination reactions, in one chlorination reactor, and/or by conducting more than two dehydrochlorination reactions, or all dehydrochlorination reactions, within a single dehydrochlorination reactor.
Method for producing 2,3,3,3-tetrafluoropropene
-
Page/Page column 4, (2010/03/04)
A method for preparing 2,3,3,3-tetrafluoropropene comprising contacting a reactant comprising CCl2=CFCH2Cl with a fluorinating agent, such as HF, under conditions effective to produce a reaction product comprising CF3CF=CH2.
