Abstract
Abstract Lubricant compositions are provided which contain: oleaginous media, and an antiwear and water tolerance improving amount of a product formed by reacting (a) a compound 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 the oxygen; (b) a substituted imidazoline of the formula: ##STR2## where one of the R 2 and R 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 2 or R 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-, alkyoxy-, alkoxymethoxy-, and oxo-substituted alkyl and alkenyl containing from 1 to about 20 carbon atoms; and (c) water; at proportions which are most preferably stoichiometric and at temperatures of from about 130° to about 170° C. Particularly contemplated are compositions in the form of lubricating oils and greases.
