Abstract

Provided is a method for producing a reclaimed refrigerant composition in which disproportionation of the reclaimed refrigerant composition to be obtained is suppressed, and additionally, acid generation resulting from the reaction between the refrigerant composition and oxygen is suppressed, as compared with known methods. Specifically, provided is a method for producing a reclaimed refrigerant composition comprising (E)-1,2-difluoroethylene, the method comprising step 1 of removing oxygen and water from a mixed refrigerant composition to be treated, the mixed refrigerant composition to be treated comprising the (E)-1,2-difluoroethylene, wherein step 1 is performed at a pressure of 5 MPa·G or less.
