Abstract

A corrosion inhibiting polyalkylenepolyamine composition comprising a mixture of (a) at least one C-alkyl-ethylene diamine, and (b) at least one di-(C-alkyl)-diethylenetriamine or at least one di-(C-alkyl)-piperazine or a mixture thereof; wherein each C-alkyl group on the ethylene diamine, diethylenetriamine and piperazine independently contains from 10 to 28 carbon atoms. Methods for preparing this composition are also disclosed, as well as methods for its use in inhibiting corrosion of corrodible metals.
