Abstract:
To provide an economically advantageous process for producing HFO-1234yf useful as a new refrigerant in sufficiently high yield by one reaction involving thermal decomposition. A process for producing HFO-1234yf and VdF from raw material containing R22, R40 and TFE, by a synthetic reaction involving thermal decomposition, which comprises (a) a step of supplying the R22, the R40 and the TFE to a reactor, as preliminarily mixed or separately, (b) a step of supplying a heat medium to the reactor, and (c) a step of bringing the heat medium in contact with the R22, the R40 and the TFE in the reactor to form the HFO-1234yf and the VdF.
Abstract:
To provide a working fluid for heat cycle, which has less influence over the ozone layer and has less influence over global warming, and which has favorable cycle performance. A working fluid for heat cycle, which contains trifluoroethylene and difluoroethylene, wherein the proportion of the content of difluoroethylene is less than 1.5 mass % based on the working fluid.
Abstract:
To provide a method for obtaining 1,1-dichloro-3,3,3-trifluoropropane by reacting 1,1-difluoroethylene with dichlorofluoromethane, which suppresses the production of chloroform as a by-product and achieves a product having a high R-243fa concentration. This method is characterized by obtaining 1,1-dichloro-3,3,3-trifluoropropane by reacting 1,1-difluoroethylene with dichlorofluoromethane in the presence of trifluoromethane.
Abstract:
To provide an economically advantageous process for producing industrially useful HFO-1234yf efficiently and in a sufficiently controlled state by one reaction involving thermal decomposition, by using readily available raw material. A process for producing 2,3,3,3-tetrafluoropropene from a raw material composition containing chlorodifluoromethane and chloromethane, by a synthetic reaction involving thermal decomposition, which comprises (a) a step of supplying the chlorodifluoromethane and the chloromethane to a reactor, as preliminarily mixed or separately, in such amounts that the chloromethane would be in a ratio of from 0.01 to 3 mol to 1 mol of the chlorodifluoromethane, (b) a step of supplying a heat medium to the reactor, and (c) a step of bringing the heat medium in contact with the chlorodifluoromethane and the chloromethane in the reactor to form the 2,3,3,3-tetrafluoropropene.

Abstract:
There is provided an industrially advantageous and efficient method of producing a Z-isomer of HCFO-1224yd or HCFO-1223xd by isomerizing an E-isomer thereof. The method produces HCFO (Z-isomer) by causing specific HCFO (E-isomer) contained in a raw material composition to undergo an isomerization reaction under a condition where the HCFO (E-isomer) is isomerized.
