  • Patent number: 7087557
    Abstract: A salicylate is disclosed, which has detergent and anti-oxidant properties, for use as a metal based detergent additive. An alkyl salicylic acid is derived from the alkylation of salicylic acid with styrene. The neutralization and subsequent overbasing of neutral salt results in an alkaline detergent, such as calcium or magnesium salicylate. The resulting detergent is a salicylic acid having multi-styrenated chains, which provide oil solubility. A method for making such a detergent is also disclosed.
