    Description / Table of Contents: On corrosion inhibitors III. Detection and properties of some protective films on iron produced with inhibitors in hydrochloric acidThe creation of a protective film by the inhibitor or one of its products is indicated by the following findings: 1If the inhibited wires are transferred into fresh hydrochloric acid free from inhibitor the protection effect remains.2The creation of the protective film, as a function of time, can be observed in the same test.3The protection effect of the inhibited wires is maintained or reduced (a) by treatment with different solvents and (b) by determining the thermal stability of the protective film.4The reduction in quaternary phosphonium and arsonium compounds observed on lead or mercury cathodes may provide a clue to the compounds taking part in the creation of the protective films.
    Notes: Für den Aufbau einer Schutzschicht durch den Inhibitor oder eines seiner Folgeprodukte sprechen folgende Befunde: 1Erhaltung der Schutzwerte nach Übertragung inhibierter Drähte in inhibitorfreie, frische Salzsäure.2Verfolgung des zeitlichen Aufbaus der Schutzschicht durch den gleichen Test.3Erhaltung oder Verringerung der Schutzwirkung der inhibierten Drähte (a) durch Behandlung mit verschiedenen Lösungsmitteln und (b) durch Bestimmung der thermischen Stabilität der Schutzschicht.4Der an Blei- bzw. Quecksilberkathoden beobachtete Abbau quaternärer Phosphonium- und Arsoniumsalze eröffnet möglicherweise einen Zugang zu den am Aufbau der Schutzschichten beteiligten Verbindungen.
