ABSTRACT:
The present invention provides a composition for use in compression refrigeration and air-conditioning comprising: (a) 1,1-dichloro-2,2,2-trifluoroethane; and (b) a sufficient amount to provide lubrication of a lubricant therefor wherein said lubricant is an aliphatic non-hydrogen containing compound, an aliphatic compound having greater than about 80 percent non-hydrogen containing atoms, or an aliphatic hydrogen-containing compound having greater than about 80 percent exterior primary hydrogens, has a viscosity of about 5 to about 150 centistokes at 37.degree. C., and is miscible in combination with said 1,1-dichloro-2,2,2-trifluoroethane in the range of about 0.degree. C. to at least +20.degree. C. The compositions may further comprise an effective amount of stabilizer.
The present composition is useful in compression refrigeration and air-conditioning equipment.
