Beschreibung
Zusammenfassung:	Una composición refrigerante que comprende (i) un hidrofluoropropeno y (ii) como un estabilizador, al menos un compuesto seleccionado de fenotiazinas y ftalatos, con la condición de que se excluyan composiciones refrigerantes de 2,3,3,3-tetrafluoropropeno (HFO- 1234yf) y fenotiazina. The present invention provides a stabilized refrigerant composition containing a hydrofluoropropene with low global warming potential (GWP) that can remain stable even in the presence of air (oxygen) for a long period of time. More specifically, the present invention provides a refrigerant composition containing a hydrofluoropropene and a stabilizer. The stabilizer is at least one member selected from the group consisting of alkylcatechols, alkoxyphenols, benzoquinones, phenothiazines, and phthalates.
