Document Type and Number:
Japanese Patent JPH01501319
Kind Code:
A
Abstract:
This invention is directed to novel compositions comprising (A) certain sulfur compounds, and (B) at least one carboxylic detergent composition. The compositions of the invention are useful as additives in lubricants and functional fluids, fuels and aqueous systems. Lubricating, fuel and functional fluid compositions containing the derivatives of the invention exhibit improved antioxidant, anti-wear, thermal stability and/or extreme-pressure properties. The compositions of the invention comprise the combination of (A) at least one sulfur compound characterized by the structural formula wherein R<1>, R<2>, R<3>, R<4>, G<1> and G<2> and x are as defined hereinafter; and (B) at least one carboxylic dispersant composition prepared by the reaction of a hydrocarbon-substituted succinic acid-producing compound with at least about one-half equivalent, per equivalent of acid-producing compound, of an organic hydroxy compound, or amine containing at least one hydrogen attached to a nitrogen atom, or a mixture of said hydroxy compound and amine.
