Abstract:
A composition of an oil-soluble ionic detergent that does not contribute metal ions to the composition, and which comprises a quaternary non-metallic pnictogen cation and an organic anion having at least one hydrocarbyl group of sufficient length to impart oil solubility to the detergent, the detergent having a total base number (TBN) to total acid number (TAN) ratio of at least 2:1 imparts ash-free basicity to a lubricant composition.

Claim (Index 13):
A method for preparing an oil-soluble ionic detergent, comprising the steps of:\n (a) providing an oil-soluble acidic substrate having at least one aliphatic hydrocarbyl group of sufficient length to impart oil solubility to the detergent, optionally in an organic solvent and optionally in the presence of a C1 to C6 alcohol; (b) admixing with said acidic substrate a molar excess of a basic compound comprising a quaternary ammonium or quaternary phosphonium compound; and (c) optionally reacting the resulting mixture with an oxo-acid.
