Abstract
Official abstract text for this publication.
To provide a method for stably storing tetrafluoropropene filled in a container for e.g. storage or transportation, without occurrence of reaction such as polymerization. A method for storing tetrafluoropropene in a gaseous-liquid state composed of a gas phase and a liquid phase in a closed container, wherein the oxygen concentration (content) in the above gas phase is adjusted to at least 3 vol ppm and less than 3,000 vol ppm at a temperature of 25° C.
First claim
Opening claim text (preview).
1 - 3 . (canceled) 4 . A container which is filled with tetrafluoropropene in a gaseous-liquid state comprising a gas phase and a liquid phase, and closed, wherein an oxygen concentration in the gas phase is at least 3 vol ppm and less than 3,000 vol ppm at a temperature of 25° C. 5 . The container according to claim 4 , wherein the oxygen concentration in the gas phase is at least 5 vol ppm and less than 1,000 vol ppm at a temperature of 25° C. 6 . The container according claim 4 , wherein the tetrafluoropropene is 2,3,3,3-tetrafluoropropene.
