Oil-soluble aliphatic acid modified high molecular weight mannich condensation products
Abstract
Abstract THE THERMAL OXIDATION STABILITY OF ALIPHATIC ACID-MODIFIED HIGH MOLECULAR WEIGHT MANNICH CONDENSATION PRODUCTS, WHICH ARE PREPARED BY REACTING (1) A HIGH MOLECULAR WEIGHT ALKYL-SUBSTITUTED HYDROXY AROMATIC COMPOUND, IN WHICH THE ALKYL-SUBSTITUENT HAS AN AVERAGE MOLECULAR WEIGHT OF FROM ABOUT 600 TO ABOUT 100,000, (2) AN AINE COMPOUND CONTAINING AT LEAST ONE HN< GROUP, (3) AN AMINAN ALIPHATIC ALDEHYDE, AND (4) AN ALIPHATIC ACID CONTAINING AT LEAST SIX CARBON ATOMS, IN THE REACTANT MOLAR RATIO OF 1:0.1-10:1-10:0.014-1.0, RESPECTIVELY, ARE IMPROVED BY REACTING SUCH MODIFIED MANNICH CONDENSATION PRODUCTS WITH FROM ABOUT 2 TO ABOUT 6 MOLES OF AN ALIPHATIC ALDEHYDE PERMOLE OF THE ALKYL-SUBSTITUTED HYDROXY AROMATIC COMPOUND USED IN PREPARING THE MODIFIED MANNICH CONDENSATION PRODUCT. THE PRODUCTS OF THE HEREIN-DESCRIBED INVENTION ARE OIL-SOLUBLE, AND ARE HIGHLY EFFECTIVE ADDITIVES FOR IMPARTING DISPERSANT-DETERGENT PROPERTIES TO LUBRICANT OIL COMPOSITIONS. LUBRICANTS CONTAINING THESE PRODUCTS PROVIDE A HIGH DEGREE OF PROTECTION AGAINST THE DEPOSITION OF SLUDGE AND VARNISH, AND CORROSION WHEN USED AS CRANKCASE LUBRICANT ADDITIVES.
