Method used for preparing chloropropene using microchannel reactors
-
Paragraph 0046-0050, (2017/05/18)
The invention relates to a method used for preparing chloropropene using microchannel reactors, and more specifically relates to a method used for preparing 1, 1, 2, 2, 3-pentachloropropane or 1, 2, 2, 3-tetrachloropropane via reaction of raw material 1, 2, 3-trichloropropene or 2, 3-dichloropropene with chlorine respectively in Corning microchannel reactors. The method comprises following steps: under light source irradiation (in preparation of 1, 1, 2, 2, 3-pentachloropropane from 2, 3-dichloropropene, light source irradiation is not necessary), chloropropene and chlorine are subjected to preheating to reaction temperature respectively, and then are introduced into a first microchannel reactor for mixing and reaction; an obtained mixture is introduced into a subsequent microchannel reactor or 2 to 4 microchannel reactors connected in series so as to obtain a chloropropene flow. Compared with the prior art, the method comprises following advantages: technology is simple; less three wastes is generated; accurate control of reaction conditions can be realized; yield is high; reaction time is short; and continuous production can be realized.
PROCESS FOR THE PRODUCTION OF CHLORINATED PROPENES
-
Paragraph 0086; 0087; 0088, (2014/07/08)
Processes for the production of chlorinated propenes are provided. The processes make use of 1,2-dichloropropane as a starting material and subject a feedstream comprising the same to an ionic chlorination process. At least a portion of any tri- and tetrachlorinated propanes not amenable to ionic chlorination conditions are removed from the ionic chlorination product stream, or, are subjected to chemical base dehydrochlorination step. In this way, recycle of intermediates not amenable to ionic chlorination reactions is reduced or avoided, as is the buildup of these intermediates within the process. Selectivity and, in some embodiments, yield of the process is thus enhanced.
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.
