    Description / Table of Contents: Investigation into corrosion inhibitors for iron in hydrofluoric acidA study (gravimetrically, measurement of the polarization resistance, tracing of potentiodynamic polarization curves) of the inhibition of the corrosion of iron in hydrofluoric acid has revealed that dibenzyl sulfoxide and lauryl pyridinium isooctyl xanthogenate (with thiourea) are efficient corrosion inhibitors. Thiourea, pyridinium xanthogenate and urotropine as well as diphenyl thiocarbazide and diphenyl guanidine exhibit good inhibiting properties. The effect can be interpreted generally in terms of the availability of free electron pairs.
    Notes: Bei einer Untersuchung (gravimetrisch, Polarisationswiderstandsmessung, Aufnahme potentiodynamischer Polarisationskurven) der Inhibierung der Korrosion von Eisen in Flußsäure erwiesen sich Dibenzylsulfoxid und Laurylpyridinium-isooctyl-xanthogenat mit Thioharnstoff als wirksame Korrosionsinhibitoren. Auch Thioharnstoff, Pyridinium-xanthogenat und Urotropin sowie Diphenylthiocarbazid und Diphenylguanidin zeigten gute Hemmwirkung. Die Wirksamkeit läßt sich allgemein durch das Vorhandensein freier Elektronenpaare erklären.
