PURPOSE:To provide a novel corrosion inhibitor having a superior corrosion inhibiting action by using a triamino compound represented by a specified general formula or its condensate with an org. acid as an effective component. CONSTITUTION:This novel corrosion inhibitor contains at least 1 kind of compound selected from 1,3,5-tris(aminomethyl)benzene and 1,3,5-tris(aminomethy)cyclohexane represented by the general formula and their condensates with an org. acid such as satd. fatty acid, satd. polycarboxylic acid, unsatd. fatty acid or unsatd. polycarboxylic acid. The corrosion inhibitor produces a remarkable corrosion inhibiting effect even at low density and has a very stable corrosion inhibiting action in an acidic aqueous soln. |
