Liquid compositions containing organic nitro compounds

A liquid composition comprising

• (A) from about 70 to about 99% by weight of at least one fluorine-containing hydrocarbon containing 1 or 2 carbon atoms and wherein fluorine is the only halogen present;
• and
• (B) from about 1 to about 30% by weight 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 ]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.sup.4 XR.sup.5 -- wherein R.sup.4 is H, hydrocarbyl, hydroxyalkyl or aminoalkyl, X is 0 or NR.sup.6, wherein R.sup.6 is H or a nitroalkyl group, and R.sup.5 is an alkylene group, or R.sup.4 X is a morpholinyl group attached to R.sup.5 through the nitrogen atom;
• and
• R.sup.1 and R.sup.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.
