Abstract 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 a soluble organic lubricant comprising at least one organic nitro compound characterized by the formulae R.sub.z N(H).sub.x [CH.sub.2 C(R.sup.1)(R.sup.2)NO.sub.2 ].sub.y (I) and CH.sub.2 [N(R)CH.sub.2 C(R.sup.1)(R.sup.2)NO.sub.2 ].sub.2 (II) wherein R is a hydrocarbyl group, a polyaminoalkyl group, or R 4 XR 5 - wherein R 4 is H, hydrocarbyl, hydroxyalkyl or aminoalkyl, X is O or NR 6 , wherein R 6 is H or a nitroalkyl group, and R 5 is an alkylene group, or R 4 X is a morpholinyl group attached to R 5 through the nitrogen atom; and R 1 and R 2 are each independently H or lower aliphatic groups; x is 0 or 1; y is 1 or 2; and z is 1 or 2, provided that the sum of x, y and z is 3. Liquid compositions also are described containing fluorine-containing hydrocarbons also containing 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.
