NEW CHEMICAL ALTERNATIVE REFRIGERANTS.

Author(s) : ADCOCK J. L.

Summary

THREE NEW FLUORINATED COMPOUNDS HAVE BEEN SYNTHESIZED: CF3 -O-CF2 CF2 H, CYCLO-CF2 -CF2 -CF2 O-AND CF3 -O-CF2 -O-CF3, HAVE NORMAL BOILING POINTS OF 268.8, 243.1 AND 263.2 K (-4.2, -29.9 AND -9.8 DEG C) AND CRITICAL TEMPERATURES OF 387.6, 361.7 AND 372.2 K (114.6, 88.7 AND 99.2 DEG C) RESPECTIVELY. THESE AND OTHER PROPERTIES INCLUDING LIQUID DENSITIES, PVT MEASUREMENTS AND HEATS OF VAPORIZATION PLACE THESE COMPOUNDS INTERMEDIATE IN PROPERTIES BETWEEN R11 AD1. THEY THEREFORE COULD FUNCTION AS REPLACEMENT WORKING FLUIDS IN MANY APPLICATIONS REQUIRING PROPERTIES IN THIS RANGE. IT IS ANTICIPATED, BUT NOT YET PROVEN, THAT STRUCTURAL FEATURES IN THESE COMPOUNDS WILL LEAD TO REDUCED ATMOSPHERIC LIFETIMES AND THUS TO REDUCED GREENHOUSE WARMING POTENTIAL.
