    摘要: A lubricating oil composition containing esters constituted with glycerol, fatty acid and boric acid, which esters having carboxylic acid residue, glycerol residue and boric acid residue at a specific proportion.The proportion for the carboxylic acid residue and glycerol residue ranges 0-2.0 mols and 1.5-2.0 mols respectively per unit mol of a boric acid residue, and the glycerol residue is 1.2 mols or more based on 1 mol of the carboxylic acid residue.Lubricating oil additives according to the invention have almost no corrosion property in bearing portions, and do not form any solid film on themselves when allowed to stand in the air.

    摘要: High alkalinity sulfurized alkylphenates of alkaline earth metals useful as lubricating oil additives and methods of making them are disclosed. A sulfurized alkylphenol is neutralized with an alkaline-earth base in the presence of an oil, a glycol, and halide ions, the glycol being present in the form of a mixture with an alcohol having a boiling point above 150.degree. C. Alcohol, glycol, water, and sediment are removed from the resultant medium and the medium is then carbonated. After carbonation, alcohol, glycol, water, and sediment are removed.
