Method used for preparing chloropropene using microchannel reactors

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.

Preparation method of 1,1,2,3-tetrachloropropene

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.

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

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 PROPENES

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

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.

PROCESS FOR THE PRODUCTION OF CHLORINATED ALKANES

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.

PROCESS FOR THE PRODUCTION OF CHLORINATED ALKANES

Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the addition of at least two chlorine atoms to an alkane and/or alkene with a catalyst system comprising one or more nonmetallic iodides and/or lower than conventional levels of elemental iodine and at least one Lewis acid. The present processes make use of sulfuryl chloride, or chlorine gas, as a chlorinating agent.

PROCESS FOR THE PRODUCTION OF CHLORINATED PROPANES AND PROPENES

Processes for the production of chlorinated propanes and propenes are provided. The present processes comprise catalyzing at least one chlorination step with one or more regios elective catalysts that provide a regioselectivity to one chloropropane of at least 5: 1 relative to other chloropropanes.

PROCESS FOR THE PRODUCTION OF CHLORINATED PROPENES

Processes for the production of chlorinated propenes are provided. The present processes make use of a feedstock comprising 1,2,3-trichloropropane and chlorinates the 1,1,2,3-tetrachloropropane generated by the process prior to a dehydrochlorination step. Production of the less desirable pentachloropropane isomer, 1,1,2,3,3-pentachloropropane, is thus minimized. The present processes provide better reaction yield as compared to conventional processes that require dehydrochlorination of 1,1,2,3-tetrachloropropane prior to chlorinating the same. The present process can also generate anhydrous HCl as a byproduct that can be removed from the process and used as a feedstock for other processes, while limiting the production of waste water, thus providing further time and cost savings.

SULFURYL CHLORIDE AS CHLORINATING AGENT

The use of sulfuryl chloride, either alone or in combination with chlorine, as a chlorinating agent is disclosed.
