PCT No. PCT/US90/02495 Sec. 371 Date May 29, 1990 Sec. 102(e) Date May 29, 1990 PCT Filed May 4, 1990.A liquid composition is described which comprises (A) a major amount of at least one fluorine containing hydrocarbon containing one or two carbon atoms; and (B) a minor amount of at least one soluble organic lubricant comprising at least one organic thiocarbamate characterized by the formulae R1R2NC(X)SC(R3R4) (C(H) (R5))aZ , or tm (I) (R1R2NC(X)SC(R3R4) (C(H) (R5))aC(X)A)2Z'(II) wherein R1 and R2 are each independently lower alkyl, aryl, aralkyl or together form a heterocyclic group in which the ring is completed trough the nitrogen; X is O or S; A is O, S or NR; R is H or a lower alkyl group; R3, R4 and R5 are each independently H, lower alkyl or aryl groups; a is 0 or 1; Z is -CN, -S(O)R6, -S(O)OR6, -S(O)2R6, -S(O)2OR6, or -C(O)Y; R6 is -H, alkyl or aralkyl; Y is -H, -OH, -R7, -OR7, -OR8OH, or -NR9R10; R7 is an alkyl, aryl or aralkyl group; R8 is an alkylene group of 1 to about 7 carbon atoms; R9 and R10 are each independently -H, alkyl, hydroxyalkyl, cycloaliphatic, or together form cyclic group in which the ring is completed through the nitrogen atom; and Z' is -R8- or -R8-A-R8-. The liquid compositions may additionally contain a polyoxyalkylene glycol or a carboxylic ester. 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 auto, home and industrial air-conditioners.
