Claims
- 1. An azeotropic or azeotrope-like composition consisting essentially of about 1-99 weight percent fluoromethyl trifluoromethyl ether and about 1-99 weight percent 1,1-difluoroethane wherein after 50 weight percent of the composition has been removed when the temperature has been adjusted to about 25.degree. C., the difference in vapor pressure of the remaining composition and the original composition is less than about 10 percent.
- 2. A process for producing refrigeration comprising condensing the composition of claim 1 and thereafter evaporating the condensate in the vicinity of a body to be cooled.
- 3. A process for producing heat comprising condensing the composition of claim 1 in the vicinity of the body to be heated and thereafter evaporating said composition.
