    Abstract: This invention relates to a liquid composition comprising (A) at least one fluorine-containing hydrocarbon containing one to three carbon atoms, and a lubricant comprising (B) at least one ester lubricant selected from the group consisting of (i) an ester of a polyhydroxy compound and a monocarboxylic acylating agent having from about 4 to about 15 carbon atoms, and (ii) an ester of polyhydroxy compound and a combination of a dicarboxylic acylating agent and a monocarboxylic acylating agent having about 7 to about 15 carbon atoms, and (C) at least one additive selected from the group consisting of an alkyl phosphite, an alkyl phosphonic acid ester, a nitrogen-containing heterocycle, and a mixture thereof. Liquid compositions also are described wherein the fluorine-containing hydrocarbons also contain other halogens such as chlorine. Methods of lubricating refrigeration systems are also described. The liquid compositions are useful particularly as refrigeration liquids in refrigerators and air-conditioners including automotive, home, commercial and industrial air-conditioners.

    Abstract: The invention relates to liquid compositions which comprises (A) at least one fluorine-containing hydrocarbon containing one to three carbon atoms; and a lubricant comprising (B) at least one carboxylic ester of (I) a polyhydroxy compound, and (II) a combination of (a) a monocarboxylic acylating agent having four or five carbon atoms, (b) a monocarboxylic acylating agent having from about 7 to about 15 carbon atoms and (c) a polycarboxylic acylating agent. In another aspect of the invention, the liquid compositions consist essentially of (A) at least one fluorine-containing hydrocarbon, and (B) at least one ester of (I) at least one polyhydroxy compound described herein and (II) at least one combination of carboxylic acylating agents as described herein. The lubricant may additionally contain (C) an additive selected from the group consisting of an alkyl phosphite, an alkyl phosphonic acid ester, a nitrogen-containing heterocycle, and a mixture thereof. 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 and industrial air-conditioners.

    Abstract: CARBOXYLIC ACID ACYLATING AGENTS ARE DERIVED FROM POLYALKENES SUCH AS POLYBUTENES, AND A DIBASIC, CARBOXYLIC REACTANT SUCH AS MALEIC OR FUMARIC ACID OR CERTAIN DERIVATIVES THEREOF. THESE ACYLATING AGENTS ARE CHARACTERIZED IN THAT THE POLYALKENES FROM WHICH THEY ARE DERIVED HAVE A MN VALUE OF ABOUT 1300 TO ABOUT 5000 AND A MW/MN VALUE OF ABOUT 1.5 TO ABOUT 4. THE ACYLATING AGENTS ARE FURTHER CHARACTERIZED BY THE PRESENCE WITHIN THEIR STRUCTURE OF AT LEAST 1.3 GROUPS DERIVED FROM THE DIBASIC, CARBOXYLIC REACTANT FOR EACH EQUIVALENT WEIGHT OF THE GROUPS DERIVED FROM THE POLYALKENE. THE ACYLATING AGENTS CAN BE REACTED WITH THE FURTHER REACTANT SUBJECT TO BEING ACYLATED SUCH AS POLYETHYLENE POLYAMINES AND POLYOLS (E.G., PENTACYTHRITOL) TO PRODUCE DERIVATIVES USEFUL PER SE AS LUBRICANT ADDITIVES OR AS INTERMEDIATES TO BE SUBJECTED TO POST- TREATMENT WITH STILL OTHER DERIVATIVES USEFUL AS LUBRICANT ADDITIVES.
