MIXTURES OF PENTAFLUOROPROPANE AND A HYDROFLUOROCARBON HAVING 3 TO 6 CARBON ATOMS

摘要

The invention discloses novel azeotrope-like mixtures of fluorinated compounds which are useful for heating and cooling as heat transfer agents and/or refrigerants. The azeotrope-like mixture comprises: (a) pentafluoropropane; and (b) a hydrofluorocarbon of the formula CxFyHz, wherein x is 3, 4, 5, or 6 and y and z are each independently 1 or a positive whole number such that the result of y/(y + z) is greater than 0.67.
