An object is to provide a hydrofluoroolefin-based or hydrochlorofluoroolefin-based azeotropic or azeotropic-like composition. The azeotropic or azeotropic-like composition contains trans-1-chloro-3,3,3-trifluoropropene and 1-chloro-1,3,3,3-tetrafluoropropene. In the azeotropic or azeotropic-like composition, 1-chloro-1,3,3,3-tetrafluoropropene exists in an effective amount to form an azeotropic or azeotropic-like mixture with trans-1-chloro-3,3,3-trifluoropropene.

Composition, aerosol composition, cleaning agent, solvent, silicone solvent, foaming agent, heat-transfer medium, fire extinguishing agent, and fumigant containing the composition, heat-transfer device containing the heat-transfer medium, and system containing the heat-transfer device

A manufacturing method of 1-chloro-3,3,3-trifluoropropene (1233zd) is provided. This manufacturing method includes a reaction in which a halogenated hydrocarbon compound having a carbon number of 3 and represented by a general formula (1) is heated:CFCl&#x2014;CH&#x2014;CHFCl&#x2003;&#x2003;(1) In the formula, a is an integer from 0 to 2, b is 1 or 2 when a=0, b is 0 or 1 when a=1, and b is 0 when a=2.

Method for producing 1,3-dichloro-3,3-difluoropropene

A method for producing 1,2-dichloro-3,3,3-trifluoropropene according to the present invention includes the step of reacting 1,1,2,3,3-pentachloropropene with a fluorinating agent where hydrogen fluoride is used as the fluorinating agent.

Method for producing 1,2-dichloro-3,3,3-Trifluoropropene

A method for isomerizing a hydrohalofluoroolefin isomer to produce a corresponding hydrohalofluoroolefin isomer includes a step contacting a composition that contains at least a hydrohalofluoroolefin isomer and that has been adjusted to 100 ppm or lower in moisture concentration, with a catalyst in a gas phase, thereby obtaining a product. This method makes it possible to suppress the catalyst performance lowering.
