DOCUMENT TYPE: Patent CA Section: 50 (Propellants and Explosives) Section cross-reference(s): 59 The fluoroalkanes have general formula CnHmFx (n = integer 1-6; m, x = integer 31; m +x = 2n or 2n + 2), but tetrafluoroethanes and pentafluoroethane are excluded. These compns. have O3-depletion potential (ODP) 0. CF3CFHCF3 and CF3(CF2)2CF2H had Cup Burner value (ISO/DIS 7075-1) 3.5 and 9, resp. .

DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) A compn. for use in mech. vapor compression-type heat transfer devices (e.g., refrigerators, heat pumps) comprises a non-Cl-contg. working fluid, preferably, tetrafluoroethane and an ester lubricant which is miscible with the working fluid at 10% over a temp. range of -50 to 80° and has a viscosity of 5-100 cSt at 40°. Useful esters include pentaerythritol partial ester of C5 straight chain or C7 branched chain carboxylic acids. .
