111224555 Nonafluoro 4 Trifluoromethyl 3 Pentanone Refrigerant Compositions Comprising a Hydrocarbon and Uses Thereof

The present invention relates to compositions for use in refrigeration and air conditioning systems comprising 111224555 nonafluoro 4 trifluoromethyl 3 pentanone and at least one chlorocarbon alcohol ketone ether ester N-difluoromethyl NN dimethylamine 11122 pentafluoro 2 pentafluoroethyl thioethane or mixtures thereof and which are also useful in systems employing a centrifugal compressor. The compositions of the present invention may be azeotropic or near azeotropic and are useful in processes for producing refrigeration or heat or as heat transfer fluids.


Provides novel refrigedant compositions and heat transfer fluids that provide unique characteristics to meet the demands of low or zero ozone depletion potential and lower global warming potential as compared to current refrigerants.
