Abstract (en)

[origin: US4514313A] 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 DEG 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.
