ABSTRACT:
Alkylsalicylate-containing detergent-dispersant additives for lubricating oils are obtained by (a) neutralizing an alkylphenol by means of an alkali metal hydroxide; (b) carboxylation of the product with carbon dioxide for maximum conversion of the initial alkali metal alkylphenate into alkali metal alkylsalicylate; (c) sulfurization-superalkalinization of the product in the presence of an alkaline earth base followed by carbonation of the product with carbon dioxide.
