A fuel composition for internal combustion engines comprising
- (a) a major portion of a fuel containing (i) at least one alcohol selected from the group consisting of ethanol and methanol and (ii) gasoline in amount of 0-50 volumes per volume of alcohol;
- and
- (b) a minor corrosion inhibition amount of, as a corrosion inhibiting agent, a reaction product of (i) an aminotriazole, (ii) an isatoic anhydride, and (iii) a C.sub.3 -C.sub.12 poly-primary amine bearing at least one free --NH.sub.2 group and at least one --NHR' group wherein R' is a C.sub.12 -C.sub.18 hydrocarbon group.
A fuel composition for internal combustion engines comprising
- (a) a major portion of a fuel containing absolute ethanol;
- and
- (b) a minor corrosion inhibiting amount, 0.0001 w %-0.005 w % of said fuel composition, of as a corrosion inhibiting agent, a reaction product of 5-amino-1,2,4-triazole, isatoic anhydride and R'NHCH.sub.2 CH.sub.2 NH.sub.2 wherein R' is a C.sub.12 -C.sub.18 alkyl hydrocarbon.
A composition comprising a reaction product of (i) an aminotriazole, (ii) an isatoic anhydride, and (iii) a C.sub.3 -C.sub.12 poly-primary amine bearing at least one free --NH.sub.2 group and at least one --NHR' group wherein R' is a C.sub.12 -C.sub.18 hydrocarbon group.
##STR3## wherein R' is a C.sub.12 -C.sub.18 n-alkyl hydrocarbon.
