Abstract:
A catalytic composition with a corrosion-inhibiting effect on metal surfaces is described. Also described, is a corrosion-inhibiting process and use of a corrosion inhibitor. Further, the catalytic composition can have a corrosion-inhibiting effect on metal surfaces in contact with an esterification medium comprising a carboxylic acid and an alcohol, wherein the composition comprises as a catalyst, a strong protonic acid and, as corrosion inhibitor, an iron(III) carboxylate.
