ABSTRACT:
The present invention provides binary azeotropic composition consisting essentially of C.sub.3 F.sub.7 --OCH.sub.3 and a second component selected from the group consisting of an unsubstituted alkane having 5 to 7 carbon atoms, methyl formate, acetone, methanol, 1,1,1,3,3,3-hexafluoro-2-propanol, methylene chloride and trans-1,2-dichloroethylene. The present invention also discloses tertiary azeotropic composition consisting essentially of C.sub.3 F.sub.7 --OCH.sub.3, a second component selected from the group consisting of methanol and 1,1,1,3,3,3-hexafluoro-2-propanol and a third component selected from the group consisting of methylene chloride and trans-1,2-dichloroethylene. The azeotropic composition of this invention may be used in various applications and in particular as refrigerant, in cleaning applications, in heat transfer applications, in coating applications, and the like.
