L-2435R-l Title: LIQUID REFRIGERANT COMPOSITIONS Abstract of the Disclosure This invention relates to a liquid composition comprising (A) a major amount of a fluorine-containing hydrocarbon, and (B) a minor amount of a soluble organic lubric- ant free of acetylenic and aromatic unsatuLation and comprising a cyclic compound characterized by the fol- lowing structure Image (I) wherein R is H, a hydrocarbyl group, or -R2COOR1, X is O or NR3, Y is CHR4, C=O, C=NR5, R1 is H or a lower hydrocarbyl group, R2 is an alkylene group, R3 is H, a hydrocarbyl group, an alkylene group joined to R5 when Y is C=N-R5 to form a cyclic moiety, -R6OR7, or -R8NR9R10, R4 is H or a hydrocarbyl group, R5 is H or an alkylene group joined with R3 when X is NR3 to form a cyclic moiety, R6 is an alkylene group, R7 is H or a hydrocarbyl group, R8 is an alkylene group, and R9 and R10 are each independently H or hydrocarbyl groups, or R9 and R10 are hydrocarbylene groups joined together to form a heterocyclic moiety, provided that when Y is CH2 and X is NR3, R3 is not a hydrocarbyl group.
