摘要： A method for conversion of a composition containing HCFO-1233zd(Z) and HCFC-244fa to form HCFO-1233zd(E) by reacting a mixture including HCFO-1233zd(Z) and HCFC-244fa in a vapor phase in the presence of a catalyst to simultaneously isomerize HCFC-1233zd(Z) to form HCFO-1233zd(E) and dehydrohalogenate HCFC-244fa to form HCFO-1233zd(E). The catalyst may be a chromium-based catalyst such as chromium trifluoride, chromium oxyfluoride, or chromium oxide, for example.

摘要： The object of the present invention is to provide a stable isotope enrichment device and a stable isotope enrichment method capable of reducing the discharge amount of toxic or combustible substances or substances causing environmental load in the atmosphere and reducing the amount of raw materials used. The present invention provides a stable isotope enrichment device, including: a distillation column group in which a plurality of distillation columns are connected in a cascade; a raw material supply line (30) that supplies a raw material into a first distillation column (1); a product line (31) that withdraws a product from another distillation column located on the secondary side of the first distillation column (1); an isotope-depleted fluid withdraw line (32) that withdraws an isotope-depleted gas or an isotope-depleted liquid from the first distillation column (1) or another distillation column located on the primary side of the one distillation column (1); an isotope exchange reactor (22) at which the isotope-depleted gas or the isotope-depleted liquid is subjected to an isotope exchange reaction, the isotope-depleted gas or the isotope-depleted liquid is regenerated such that the concentration of molecules containing a target stable isotope in the isotope-depleted gas or the isotope-depleted liquid approaches the natural abundance ratio, and an isotope-regenerated gas or an isotope-regenerated liquid is produced; and an isotope-regenerated fluid return line (33) that re-supplies the isotope-regenerated gas or the isotope-regenerated liquid into the first distillation column (1).

摘要： The present disclosure provides a method for conversion of a mixture of high-boiling fluorinated components comprising 1,1,3,3-tetrachloro-1-fluoropropane (HCFC-241fa), 1,3,3-trichloro-1,1-difluoropropane (HCFC-242fa), 1,1,3-trichloro-1,3-difluoropropane (HCFC-242fb), 3,3-dichloro-1,1,1-trifluoropropane (HCFC-243fa), 1,3-dichloro-1,1,3-trifluoropropane (HCFC-243fb), 3-chloro-1,1,1,3-tetrafluoropropane (HCFC-244fa), their isomers, and combinations thereof, to 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd). Heavy impurities, such as oligomers and other high boiling impurities, that are present may be purged during the process to prevent yield loss and reduction of catalyst efficacy.

摘要： The present disclosure provides a method for co-production of hydrofluorocarbons, which includes the steps of: preheating a mixture of chlorinated olefin and hydrogen fluoride; transferring the mixture to the top of a reactor; simultaneously introducing 1,1,1,2,3,3-hexafluoropropene and dichloromethane to the middle of the reactor for reaction; dividing the reactor into three to six sections; filling each section with a catalyst; obtaining reaction products at an outlet of the reactor; and separating the reaction products to obtain various hydrofluorocarbon products, respectively. The present disclosure has the advantages of a high yield, an optimal selectivity and a low energy consumption.
