Abstract
Abstract 1.0:0-0.7:0.1-10:1.0-10, OIL SOLUTIONS OF BORON-CONTAINING DERIVATIVE OF PRODUCTS OF MANNICH REACTION BY CONDENSATION OF 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 A HN< GROUP, AND (4) AN ALDEHYDE IN THE RESPECTIVE MOLAR RATIO OF WHEREIN THE BORON CONTENT OF SAID DERIVATIVE OF THE MANNICH REACTION EXPRESSED AS A BORON TO NITROGEN WEIGHT RATIO (B/N) IS IN THE RANGE OF 0.1-5.5:1.0 AND SAID BORON DERIVATIVE IS PRESENT IN WEIGHT CONCENTRATIONS OF 0.05 TO 70 PERCENT AS SOLUTE IN MINERAL OIL OF THE LUBRICATING OIL TYPES. SUCH OIL SOLUTIONS ARE USEFUL AS CRANKCASE LUBRICATING COMPOSITIONS, OR AS CONCENTRATES FOR FORTIFYING USED CRANKCASE LUBRICATING COMPOSITION AND FOR PREPARATION OF CRANKCASE LUBRICATING COMPOSITON. SUCH SOLUTIONS PROVIDE DETERGENCY, DISPERSANCY AND ANTIOXIDANT PROPERTIES NECESSARY FOR CRANKCASE OIL FUNCTION UNDER HIGH SEVERITY ENGINE OPERATION.
