Polyoxylated Amines, Amides, and Imidazolines

Polyoxylated Amines, Amides, and Imidazolines Polyoxyalkylene Amines [Pg.92]

A mixture of C-alkyl-ethylene diamine and di-(C-alkyl)-diethylenetriamine, with an alkyl side chain of 8 to 26 carbon atoms is suitable [ 1876] as a corrosion inhibitor. This product can be further reacted with an alkylating agent or an alkylene oxide [836,837]. [Pg.92]

The inorganic nitrite used as a corrosion inhibitor in aqueous alkylene glycol or polyoxyalkylene glycol solutions can be replaced with polyoxyalkylene amines [1263,1264]. Such polyoxyalkylene amines impart corrosion inhibition to the liquid in contact with the metal and the metal in contact with the vapors of the aqueous composition. Aqueous compositions containing the glycol and the polyoxyalkylene amine also exhibit a low foaming tendency. [Pg.92]

In highly acidic environments a reaction product of an isobutyraldehyde and an alkylene amine compound with an alkylsulfopropionic amide group is recommended [1888,1889]. The alkylene amine compound can be the product of a reaction of equimolar amounts of N-dodecylmercaptan, methyl methacrylate, and diethylenetriamine. [Pg.93]

Dimerized fatty acid thioesters (with a dithiol) in combination with fatty amines are sulfur-containing corrosion inhibitors [888]. The corrosion inhibitor solvent is preferably a hydrocarbon. [Pg.93]
