Abstract

The invention is directed to a ternary azeotrope-like mixture consisting essentially of effective amounts of 1,1,1,3,3-pentafluoropropane, 1-chloro-3,3,3-trifluoropropene, and hydrogen fluoride.

1 . A composition comprising a ternary azeotrope-like mixture consisting essentially of effective amounts of 1,1,1,3,3-pentafluoropropane, 1-chloro-3,3,3-trifluoropropene, and hydrogen fluoride. 
     
     
         2 . The composition of  claim 1  wherein said ternary azeotrope-like mixture consists of effective amounts of 1,1,1,3,3-pentafluoropropane, 1-chloro-3,3,3-trifluoropropene, and hydrogen fluoride. 
     
     
         3 - 6 . (canceled) 
     
     
         7 . A ternary azeotrope-like composition comprising effective amounts of 1,1,1,3,3-pentafluoropropane, 1-chloro-3,3,3-trifluoropropene, and hydrogen fluoride. 
     
     
         8 - 9 . (canceled) 
     
     
         10 . The ternary azeotrope-like of  claim 7  consisting of about 24 to about 45 weight percent 1,1,1,3,3-pentafluoropropane; about 42 to about 65 weight percent 1-chloro-3,3,3-trifluoropropene; and about 0.5 to about 22 weight percent hydrogen fluoride. 
     
     
         11 - 18 . (canceled)
