| 摘要 |
A corrosion-inhibited liquid alcohol antifreeze/coolant composition comprising aliphatic C5-C16 monobasic and C5-C16 hydrocarbyl dibasic acids/salts, a hydrocarbyl azole, and a hydrocarbyl alkali metal sulfonate which is either a C10-C20 alkyl benzene alkali metal sulfonate or a C10-C20 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.
