Abstract
A composition including: at least one (hydro)halogenated olefin having the chemical formula: CX1X2═CX3X4 (I) where X1 is selected from F and Cl, and where X2, X3 and X4 are independently selected from H, F and Cl; and, at least one aliphatic alkene, having a boiling point of less than or equal to 80° C. measured at 1013 hPa; wherein the (hydro)halogenated olefin is solely in gaseous form or in the form of a liquid-gas equilibrium.

A composition comprising:
- at least one (hydro)halogenated olefin having the chemical formula:
- CX1X2═CX3X4 (I)
- where X1 is selected from F and Cl, and where X2, X3 and X4 are independently selected from H, F and Cl;
- and,
- at least one aliphatic alkene, having a boiling point of less than or equal to 80° C. measured at 1013 hPa;
- wherein the (hydro)halogenated olefin is solely in gaseous form or in the form of a liquid-gas equilibrium.
A method of using at least one aliphatic alkene, having a boiling point of less than or equal to 80° C., measured at 1013 hPa, to stabilize at least one (hydro)halogenated olefin having the chemical formula:
- CX1X2═CX3X4 (I)
- where X1 is selected from F and Cl, and where X2, X3 and X4 are independently selected from H, F and Cl.
