Abstract: The present invention provides a lubricating oil composition comprising a base oil, an aspartic acid derivative and an aliphatic amine compound. The lubricating oil composition is ideal as an industrial lubricating oil such as for example for a hydraulic working oil in hydraulic equipment. Primary amine, secondary amine, diamine, and/or tertiary amines may be employed for the aliphatic amine compound.

Abstract: The present invention aims to obtain a lubricating oil composition with good corrosion resistance properties, strong sludge inhibition and also superior energy saving properties for use in all kinds of lubricating oil compositions which use highly refined base oils, in particular in machine oils, turbine oils, compressor oils, hydraulic oils, gear oils, sliding friction oils, bearing oils and calibration oils. To this end the invention provides a lubricating oil composition comprising a base oil having a sulphur content of not more than 300 ppm, an aspartic acid derivative and an epoxidised ester compound.

Abstract: The present invention aims to provide a lubricating oil composition capable of use in for example the bearings of a high-speed main shaft having ceramics ball antifrication bearings operating under severe conditions of high speed and high load. To this end the present invention provides a lubricating oil composition, in particular for lubrication of ceramics, comprising a base oil; and at least one additive selected from the group consisting of: (i) an acid amide obtainable by reacting an amine with a saturated monocarboxylic acid having from 12 to 30 carbons or an unsaturated monocarboxylic acid having from 18 to 24 carbons; (ii) sarcosinic acid; and (iii) an aspartic acid derivative.

Abstract: The present invention involves the addition of an aspartic acid derivative and a fatty acid ester of a polyhydric alcohol to a base oil of, e.g., mineral oil or synthetic oil type. By including these additives, a lubricating oil composition having excellent rust-preventing properties, reduced friction coefficient and excellent energy-saving properties and so being suitable for industrial lubricating oils can be obtained. Also, by further adding an epoxy compound and by adding also a fatty acid amine, it is possible to obtain a lubricating oil composition even more endowed with rust-preventing properties and energy-saving properties.
