Sung, R L

An anti-corrosion additive composition for motor fuels containing a minor amount (i.E., from 1 10%) of a short chain aliphatic alcohol that is prepared by reacting substantially equal molar amounts of maleic anhydride and a hydrocarbon-substituted mono primary amine or hydrocarbon-substituted mono primary amine or hydrocarbon-substituted mono primary ether amine to produce a maleamic acid intermediate reaction product followed by (b) reacting said intermediate product of (a) with a substantially equal molar amount of a heterocyclic selected from the group consisting of 5-amino-1,3,4-thiadiazole-2-thiol or benzotriazole, said hydrocarbon-substituted mono primary amine being represented by the formula: R-NH/sub 2/ in which R is a monovalent hydrocarbyl radical having from about 6 to about 20 carbon atoms or a hydrocarbyl aminoalkylene radical in which the hydrocarbyl group has from 6 to about 20 carbon atoms and in which the divalent alkylene group has from 2 to 3 carbon atoms, and said hydrocarbon-substituted mono primary ether amine being represented by the formula: R-(O-(CH2)N)X-(O-CH2-CH(-CH3))Y-NH2 in which R is a hydrocarbyl radical having from about 6 to about 20 carbon atoms and when y is O, x is 1 and n is an integer from 1 to 4 and when x is O, y has a value of 1 to 10.
