Boron-containing high molecular weight mannich condensation
Abstract
Abstract OIL-SOLUBLE BORON-CONTAINING DERIVATIVES OF PRODUCTS OF MANNICH CONDENSATION FROM REACTANTS (1) A HIGH MOLECULAR WEIGHT ALKYL-SUBSTITUTED HYDROXYAROMATIC COMPOUND WHOSE ALKYL SUBSTITUENT HAS UPWARD FROM 40 TO 20,000 CARBON ATOMS, (2) A LOWER ALKYL-SUBSTITUTED PHENOL WHOSE ALKYL GROUP HAS 2 TO 20 CARBON ATOMS, (3) AN AMINE WHICH CONTAINS AN HN<GROUP, AND (4) AN ALDEHYDE IN THE RESPECTIVE MOLAR RATIO OF 1.0:0-7:0.1-10:1.0-10 WHEREIN THE BORON CONTENT EXPRESSED AS A BORON TO NITROGEN WEIGHT RATIO (B/N) IS IN THE RANGE OF 0.15-5:1.0. THE BORON DERIVATIVES AS SOLUTES IN WEIGHT CONCENTRATIONS OF 0.05 TO 70 PERCENT DISSOLVED IN MINERAL OIL OF THELUBRICATING OIL TYPES ARE USEFUL AS CRANKCASE LUBRICATING COMPOSITIONS, CONCENTRATES FOR FORTIFYING USED CRANKCASE LUBRICATING COMPOSITION AND FOR PREPARATION OF CRANKCASE LUBRICATING COMPOSITIONS. THOSE BORON DERIVATIVES PROVIDE DETERGENCY, DISPERSANCY AND ANTI-OXIDANT PROPERTIES TO LUBRICATING OILS.
