ABSTRACT:
Organic lubricant compositions are provided containing a lubricating improving amount of a salt of (a) an alkyl, long chain alkyl acid phosphonate having the formula: ##STR1## where R' is a substantially unbranched paraffinic alkyl group containing from about 10 to about 36 carbon atoms, and R is a hydrocarbyl group containing from 1 to about 4 carbon atoms with at least one hydrogen atom present on the carbon atom which is bonded to oxygen and (b) a substituted imidazoline of the formula: ##STR2## where one of the R.sup.2 and R.sup.3 substituents must be a substantially unbranched paraffinic or olefinic hydrocarbyl group containing from about 12 to about 35 carbon atoms; and the other R.sup.2 or R.sup.3 substituent is selected from the group consisting of: paraffinic alkyl containing from 1 to about 35 carbon atoms, alkenyl containing from 1 to about 35 carbon atoms, and hydroxy, alkoxy, alkoxymethoxy, and oxo-substituted alkyl and alkenyl containing from 1 to about 20 carbon atoms. Particularly contemplated are lubricating oils and greases containing the aforementioned alkylamine salts as anti-wear agents and friction modifiers.
