ABSTRACT:
A corrosion-inhibited liquid alcohol antifreeze/coolant composition comprising aliphatic C.sub.5 -C.sub.16 monobasic and C.sub.5 -C.sub.16 hydrocarbyl dibasic acids/salts, a hydrocarbyl azole, and a hydrocarbyl alkali metal sulfonate which is either a C.sub.10 -C.sub.20 alkyl benzene alkali metal sulfonate or a C.sub.10 -C.sub.20 alpha-olefin alkali metal sulfonate having an average molecular weight in the range 200-2000 is described. Aqueous corrosion-inhibited antifreeze/coolant compositions based on the above-described concentrate composition, where said concentrate is diluted with 10-90 weight percent water, are also described.
