The use as corrosion inhibitors of the compounds formed by reacting guanidine-type compounds with polyamines. These compounds are formed by the reaction of guanidine-type compounds, (including compounds which although not guanidine-type compounds are capable of forming guanidine-type compounds). In general, guanidine-type compounds are those which contain the residue and may be illustrated by the following: where at least one of the R''s, which may or may not be the same, is a substituted group, for example alkyl, aryl, cycloalkyl, alkaryl, aralkyl, etc; and derivatives thereof. An example of a compound which is not itself a quanidine type compound but is capable of forming a guanidine type compound is cyanamide NH2CN which reacts with itself to form dicyandiamide. |
