ABSTRACT:
A corrosion inhibitor for use in water and liquid alcohol antifreeze/coolant compositions comprising the combination of a C.sub.5 -C.sub.16 aliphatic monobasic acid or the alkali metal, ammonium, or amine salt of said acid, a C.sub.5 -C.sub.16 hydrocarbyl dibasic acid or the alkali metal, ammonium, or amine salt of said acid, and a hydrocarbyl triazole gives synergistic corrosion protection to metal surfaces as compared with formulations containing either the monoacid or diacid component alone, or formulations containing other conventional corrosion inhibitors.
