Abstract
The present invention relates to a method for storing, in a closed container, a composition comprising 1,1,1,2,3,3-hexafluoropropane in a liquid/gas state composed of a liquid phase and of a gas phase, characterized in that i) a stream comprising 1,1,1,2,3,3-hexafluoropropane is injected into said container, said stream comprising an oxygen concentration of at most 5000 ppm by volume at a temperature of 25° C., and ii) the container is closed after injection of said stream. The present invention also relates to a container for storing 1,1,1,2,3,3-hexafluoropropane.
Claims10
A method for storing, in a closed container, a composition composed of a liquid phase and a gas phase, the composition comprising 1,1,1,2,3,3-hexafluoropropane, the method comprising
- i. injecting a stream comprising 1,1,1,2,3,3-hexafluoropropane into said container, said stream comprising an oxygen concentration of at most 5000 ppm by volume at a temperature of 25° C., and
- ii. closing the container after injection of said stream.
A closed container for storing a composition composed of a liquid phase and a gas phase, the composition comprising 1,1,1,2,3,3-hexafluoropropane and oxygen, wherein an oxygen concentration in said gas phase is at most 5000 ppm by volume at a temperature of 25° C.
