Abstract
Abstract High molecular weight Mannich condensation products of (1) high molecular weight alkyl-substituted hydroxyaromatic compounds whose alkyl substituent has upward from 40 to 20,000 carbon atoms, (2) an amine which contains an AND (3) AN ALDEHYDE IN THE RESPECTIVE REACTANT MOLAR RATIO OF 1: 0.1-10:1.0-10 CONDENSED WITH A BORON COMPOUND ARE NOVEL DISPERSANT-DETERGENT LUBRICANT OIL ADDITION AGENTS. Solutions of those addition agents in lubricant oil are novel and unique compositions affording anti-sludge and varnish deposition and corrosion inhibition.
