Síntesis y caracterización de “tanatos” de lantano como inhibidores de la corrosión

ABSTRACT Tannins are polyphenols synthesized by plants. They are found in Quebracho (Schinopsis Balansae) wood, Tara (Caesalpinia spinosa) fruits, etc. They have been incorporated in the coating industry as "antifouling" agents and as corrosion inhibitors in acidic solutions. Moreover, lanthanum solutions have a great inhibitory effect over SAE 1010 steel corrosion. The aim of this study was to obtain two types of lanthanum "tannate" with low solubility, so they can be incorporated as corrosion inhibitors in temporary protective coatings, those that protect the metal during transportation and ...
