Method used for preparing chloropropene using microchannel reactors
-
Paragraph 0035-0040; 0088-0089, (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.
Compositions comprising 2,3,3,3-tetrafluoropropene, 1,1,2,3-tetra-chloropropene, 2-chloro-3,3,3-trifluoropropene, or 2-chloro-1,1,1,2-tetrafluoropropane

Page/Page column 5, (2016/05/09)
The present disclosure relates to compositions comprising 2,3,3,3-tetrafluoropropene that may be useful as heat transfer compositions, aerosol propellants, foaming agents, blowing agents, solvents, cleaning agents, carrier fluids, displacement drying agents, buffing abrasion agents, polymerization media, expansion agents for polyolefins and polyurethane, gaseous dielectrics, extinguishing agents, and fire suppression agents in liquid or gaseous form. Additionally, the present disclosure relates to compositions comprising 1,1,2,3-tetrachloropropene, 2-chloro-3,3,3-trifluoropropene, or 2-chloro-1,1,1,2-tetrafluoropropane, which may be useful in processes to produce 2,3,3,3-tetrafluoropropene.
PROCESS FOR THE PRODUCTION OF CHLORINATED PROPANES AND/OR PROPENES
-
Paragraph 0079, (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.
