2617B ABSTRACT OF THE INVENTION This invention relates to a liquid composition comprising (A) at least one fluorine-containing hydrocarbon containing one to three carbon atoms; and (B) at least one carboxylic ester of (I) a neo hydroxy compound selected from the group consisting of (i) a neo hydroxy compound with two or three hydroxyl groups, (ii) a mixture of neo hydroxy compounds having an average of less than about 3.5 hydroxyl groups per hydroxy compound, (iii) a neo hydroxy compound having five or more hydroxyl groups per hydroxy compound, and (iv) a mixture of neo hydroxy compounds having an average of greater than 4.5 hydroxyl groups per hydroxy compound, and (II) a combination of (a) a monocarboxylic acylating agent having four or five carbon atoms and (b) a monocarboxylic acylating agent having from about 7 to about 15 carbon atoms, provided that when (I) is (i) or (ii) then greater than 55% of the ester groups are derived from (IIa), and provided that when (I) is (iii) or (iv) then greater than 55% of the ester groups are derived from (IIb). Liquid compositions also are described wherein the fluorine-containing hydrocarbons also contain other halogen such as chlorine. The liquid compositions are useful particularly as refrigeration liquids in refrigerators and air-conditioners including automotive, home, commercial, and industrial air-conditioners.
