CORROSION INHIBITION BY ETHOXYLATED FATTY AMINE SALTS OF MALEATED UNSATURATED ACIDS

摘要

A method for inhibiting corrosion of a metal surface bearing a corrosionproduct including ferrous ions is disclosed. The method comprises applying tothe surface a salt of an ethoxylated amine and a reaction product of analcohol and a fatty acid maleic anhydride adduct produced by a reactionbetween maleic anhydride and an unsaturated fatty acid. Related compositionsare also disclosed.
