Abstract: The present invention provides an anti-wear compound selected from phosphorus compounds as represented by the following General Formula (2) or metal salts thereof as represented by the following General Formula (3).

Abstract: Overbased MgO dispersions with high magnesium content and acceptably low viscosities are prepared without gel formation by heating to 280-360° C. under high pressure in a sealed reactor a mixture of MgO, selected dispersants, low MW carboxylic acids, water and a hydrocarbon solvent having a boiling point below 280° C. No additional solubilizing or dispersing agents, promoters or reactants such as carbon dioxide, amines, alcohols etc are needed to obtain the desired dispersions. Compositions such as lubricating oils and fuels containing the overbased magnesium dispersions as additives are also disclosed.

Abstract: Disclosed is lubricant base oil that is excellent in lubricity, sludge solubility, low viscosity, and low temperature characteristics and capable of realizing low volatility. The lubricant base oil contains as its main component a diester or triester synthesized from a divalent or trivalent carboxylic acid of 9 or less carbon atoms and a monovalent glycol ether such as an alkylene glycol monoalkyl ether of 3 to 25 carbon atoms and is useful as base oil for lubricating oil and grease. Di(hexyloxyethyl) adipate may be cited as an appropriate example of the diester.
