TECHNICAL FIELD
5 [0001]
An embodiment of the present invention relates to a composition
containing trans-1-chloro-3,3,3-trifluoropropene and 1-chloro-1,3,3,3-
tetrafluoropropene.
10 BACKGROUND ART
[0002]
Hydrofluoroolefins (HFOs) and hydrochlorofluoroolefins (HCFOs) have
excellent environmental performance such as a short lifetime in the atmosphere
and a low global warming potential. For example, the patent literature 1
15 describes that cis-1-chloro-1,3,3,3-tetrafluoropropene and trans-1-chloro-1,3,3,3-
tetrafluoropropene, which are HCFOs, can be used as a heat-transfer medium for
refrigeration cycle systems, high-temperature heat pump systems, and organic
Rankine cycles with small environmental impact.

An object of an embodiment of the present invention is to provide a
composition in which HFOs or HCFOs exist in an effective amount to form an
azeotropic mixture or an azeotropic-like mixture. Alternatively, an object of an
embodiment of the present invention is to provide a composition including HFOs
5 or HCFOs, which has extremely low contribution to ozone depletion and global
warming, exhibits small composition changes, and functions as heat transfer
medium for refrigeration cycle systems, heat pump systems, and organic Rankine
cycle systems. Alternatively, an object of an embodiment of the invention is to
provide a heat-transfer method and a method of converting thermal energy to
10 mechanical energy in the above systems.
