Summary

A volumetric method for the quantitative determination of Sulphoxides has been developed, based on their oxidation to sulphones by dichromate in presence of 5 M sulphuric acid at 105–110°C. Excess dichromate is titrated by ferrous ammonium sulphate solution. The method is also applicable to the determination of Sulphoxides in metal sulphoxide complexes.

Zusammenfassung

Zur Bestimmung von Sulfoxiden wurde ein volumetrisehes Verfahren ausgearbeitet, das auf der Oxydation zu Sulfonen mit Hilfe von Dichromat in Gegenwart von 5 M Schwefelsäure (105–110°C) beruht. Der Überschuß an Dichromat wird mit Eisen(II)-ammoniumsulfatlösung zurücktitriert. Der Verfahren eignet sich auch zur Sulfoxidbestimmung in Metallsulfoxidkomplexen.
