METHOD FOR ANTI-CORROSION OF METALS IN CONTACT WITH WATER FROM THE TOP FRACTION OF THE CRUDE OIL DISTILLATION.

摘要

Compositions for inhibiting the corrosion of metals which are contacted with water containing a chloride contaminant will comprise a mixture of a salt of a dicarboxylic acid and an aliphatic amine with a cyclic amine or a mixture of cyclic amines. The composition is exemplified by a salt of a dicarboxylic acid and oleylamine with a volatile cyclic amine comprising a mixture of pyridine, picoline, lutidine, aniline, quinoline, isoquinoline, toluidine, and heavy pyridine.
