PURPOSE:To obtain a corrosion inhibitor which is harmless to man and beast and has an improved corrosion inhibiting effect by adding amine to a mixture of specified acylsarcosine with specified benzotriazole. CONSTITUTION:Amine is added to a mixture of acylsarcosine represented by formulaI(where n is an integer of 4-22) with benzotriazole represented by formula II (where R1 is H, halogen, lower alkyl, hydroxyl or carboxyl; and R2 is H or 7-17C acyl). The resulting corrosion inhibitor maintains its corrosion inhibiting performance to various kinds of metals over a long term, and it is harmless to man and beast. |
