Fatty amines and diamines can be used for corrosion inhibition in oil-producing wells. Typically, these products are dispersed as salts of organic acids such as fatty acids or petroleum sulfonic acids. Fatty amines and diamines have also been used as corrosion inhibitors in the transportation and storage of petroleum products. Quaternary ammonium salts, including dialkyldimethy-lammonium, monoalkyltrimethylammonium and mono-alkyldimethylbenzylammonium, are good corrosion inhibitors.
