Abstract
A specific monocarboxylic acid with even-numbered carbon atoms, sebacic acid, or a salt thereof is used as a corrosion inhibitor. Alternatively, a specific aliphatic monocarboxylic acid, sebacic acid, or a salt thereof is blended with a specific aliphatic oxycarboxylic acid, a specific polycarboxylic acid, or a salt thereof to prepare a corrosion inhibitor. These corrosion inhibitors can be used in a cooling water system using low-hardness water and in water systems wherein a water flow velocity above a given level cannot always be secured, whereby a high corrosion control performance can be exhibited without imposing unfriendly loads on the environment.
