    Abstract: Provided is a method for producing (Z)-1-chloro-2,3,3-trifluoro-1-propene where (E)-1-chloro-2,3,3-trifluoro-1-propene and water can be efficiently removed and (Z)-1-chloro-2,3,3-trifluoro-1-propene with higher purity can be obtained at a higher recovery ratio. The method for producing (Z)-1-chloro-2,3,3-trifluoro-1-propene includes: distilling a distillation composition which contains (Z)-1-chloro-2,3,3-trifluoro-1-propene, (E)-1-chloro-2,3,3-trifluoro-1-propene and water to remove (E)-1-chloro-2,3,3-trifluoro-1-propene and water as an azeotropic composition or an azeotropic-like composition.

    Abstract: There is provided an efficient method for producing 1-chloro-2,3,3,3-tetorafluoropropene, with fewer by-products such as 2,3,3,3-tetrafluoropropene and 1,1,1,2-tetrafluoropropane which are over-reduced products, in a method of obtaining 1-chloro-2,3,3,3-tetorafluoropropene by reducing 1-1-dichloro-2,3,3,3-tetrafluoropropene. A method for producing 1-chloro-2,3,3,3-tetrafluoropropene, comprising: reacting 1,1-dichloro-2,3,3,3-tetrafluoropropene with hydrogen in a gas phase in the presence of a palladium catalyst-carrying carrier in which a palladium catalyst having a specific surface area of 40 m2/g or less is carried on a carrier.

    Abstract: A heat cycle system with high durability, which employs a working fluid for heat cycle containing trifluoroethylene having a low global warming potential. A heat cycle system, having a circulation path in which a working fluid for heat cycle containing trifluoroethylene is circulated from a compressor via a condenser, an expansion valve and an evaporator to the compressor, wherein the compressor has in its electrical circuit a current-limiting apparatus capable of limiting the current within 6 milliseconds after the heat cycle system enters into an abnormal operation state.
