(JA) トランス-1,2-ジフルオロエチレン(HFO-1132(E))と1,1,1-トリフルオロエタン(HFC-143a)とを含む組成物、並びにHFO-1132(E)とHFC-143aとを含む組成物から、HFO-1132(E)及びHFC-143aを分離する方法
要約
(EN)

PROBLEM TO BE SOLVED: To provide an azeotropic or azeotropic composition containing HFO-1132(E) and HFC-143a, and a method for separating HFO-1132(E) and HFC-143a from a composition containing HFO-1132(E) and HFC-143a.

SOLUTION: A composition, which is a composition containing a refrigerant, and the refrigerant is an azeotropic or azeotropic like one and contains trans-1,2-difluoroethylene (HFO-1132(E)) and 1,1,1-trifluoroethane (HFC-143a), and the content ratios of HFO-1132(E) and HFC-143a to the total amount of HFO-1132(E) and HFC-143a in the refrigerant are 80 mass% or more and 20 mass% or less, respectively, is provided as means therefor.
