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.
Claims12
A method for producing detergent additives for lubricants and fuels comprising reacting fatty acid represented by the formula RCOOH in which R is a hydrocarbyl radical of about 7 to about 99 carbon atoms with aminoalkanolamine represented by the formula H.sub.3-a N(CH.sub.2 CH.sub.2 NR'CH.sub.2 CH.sub.2 OH).sub.a where R' is H or CH.sub.2 CH.sub.2 NH.sub.2 and a is 1, 2, or 3.
