This invention relates to a composition comprising: (A) a major amount of a fluorine-containing hydrocarbon containing one or two carbon atoms; and (B) a minor amount of a soluble tertiary amide represented by the formula <IMAGE> wherein a is one or two, provided that when a is one, R is a hydrocarbyl group or a hydrocarbylpolyoxyalkylene group, and when a is two, R is a hydrocarbylene group; each R2 is independently hydrogen or an alkyl group having from 1 to about 8 carbon atoms; b is one or two; X is oxygen or N-R3; R3 is a hydrocarbyl group having 1 to about 18 carbon atoms or -C(O)R4, R4 is a hydrocarbyl group or a hydrocarbylpolyoxyalkylene alkyl group. The present invention provides compositions which are useful as refrigeration liquids in refrigerators and air-conditioners including auto, home and industrial air-conditioners. The invention provides tertiary amides which are compatible with fluorine-containing hydrocarbons used in refrigerators and air conditioners. The tertiary amides act as a lubricant for air-conditioners.
