    Description / Table of Contents: Basic processes with the corrosion of metals in organic solvents (11)Research has been carried out into the corrosion mechanism of Zn, Fe and Ni in anhydrous primary alcohols of different chain lengths. The results can be explained from an analogy to aqueous solutions although the chain length of the plays an important part. With the corrosion of iron in the multi-components system heptane-ethanol-HCl(H2SO4)-O2, a phase segregation can be observed which leads to processes similar to atmospheric corrosion. The destruction of the metal is due to a strongly acid solution phase deposited on the surface, governed by an electrolytic mechanism. The practice Of corrosion testing and corrosion Protection can be based on the Principles and methods conventionally used for corrosion in aqueous media.
    Notes: Der Mechanismus der Korrosion won Zn, Fe und Ni in HCl-haltigen wasserfreien, primären Alkoholen verschiedener Kettenlänge wird untersucht. Die Resultate können aus der Analogie zu wäßrigen Lösungen erklärt werden, wobei jedoch die Kettenlänge des Alkohols eine wichtige Rolle spielt. Bei der Eisenkorrosion im Mehrkomponentensystem Heptan-Äthanol-HCl(H2SO4)-O2 läß;t sich eine Phasentrennung beobachten, die zu ähnlichen Prozessen wie bei der atmosphärischen Korrosion führt. Die Zerstörung des Metalls erfolgt aus einer auf der Oberfläche stark Sauren Lösungsphase nach einem elektrolytischen Mechanismus. Die Praxis der Korrosionsprüfung und des Korrosionsschutzes kann sich auf die aus dem Gebiet der Korrosion in wäß;rigen Medien erprobten Prinzipien und Methoden stützen.
