  • Fuel and lubricant additives from aminoalkylalkanolamines
    Patent number: 4230588
    Abstract: Fatty acids are reacted with aminoalkylalkanolamines to form amide amine alcohols, multiamide-alcohols, or multiamide-esters that have good detergent properties in fuels and lubricants. In an embodiment of the invention reaction products in which all of the reactant nitrogen has not been amidated are further reacted with arylsulfonic acid to provide more water tolerant products.

  • Ashless additives for lubricating compositions
    Patent number: 3960937
    Abstract: Superior ashless additives for lubricants are prepared by a process comprising first introducing a petroleum sulfonic acid and a polyamine to a reaction zone and subsequently introducing a cyclic anhydride of a dicarboxylic acid into the reaction zone. In another embodiment, the solids content of the additives is reduced to acceptable levels by removal of free SO.sub.2 from the petroleum sulfonic acid prior to preparing the additive. Lubricating oil compositions containing these ashless additives are also provided.
