Paragraph 0050; 0074-0092, (2020/11/01)
The invention relates to a method for producing a 1, 1-dichloro-3, 3, 3-trifluoropropene with high added value by taking trifluoromethane and trichloroethylene as raw materials. According to the method, a catalytic system composed of a main catalyst and a catalytic auxiliary agent of specific types in a special proportion is adopted; wherein the active component of the main catalyst is selected from one or more of Fe, Co, Ni, Ru, Rh, Pd, Pt, Cu, Ag and Au, multi-stage micro/mesoporous Cr2O3 is adopted as a carrier, and a metal oxide and/or a rare earth auxiliary agent is adopted as a catalyticauxiliary agent, so that the selectivity on the target product 1, 1-dichloro-3, 3, 3-trifluoropropene is effectively improved. According to the method disclosed by the invention, not only the resource utilization of the byproduct trifluoromethane is promoted, but also the types of raw materials of the 1, 1-dichloro-3, 3, 3-trifluoropropene product are expanded, and remarkable economic benefits and social benefits are generated.

-
Paragraph 0061; 0063, (2015/02/25)
The present invention provides routes for making 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) from commercially available raw materials. More specifically, this invention provides routes for HCFO-1233zd from inexpensive and commercially available trifluoromethane (HFC-23).
PROCESS FOR THE PRODUCTION OF CHLORINATED AND/OR FLUORINATED PROPENES
-
Page/Page column 8, (2011/04/25)
The present invention provides one-step processes for the production of chlorinated and/or fluorinated propenes. The processes provide good product yield with low, e.g., less than about 20%, or even less than 10%, concentrations of residues/by-products. Advantageously, the processes may be conducted at low temperatures than 500° C. so that energy savings are provided, and/or at higher pressures so that high throughputs may also be realized. The use of catalysts or initiators may provide additional enhancements to conversion rates and selectivity, as may adjustments to the molar ratio of the reactants.
