Tüpfelreaktionen zum Nachweis von Hydroxylamin, Hydrazin und Ascorbinsäure in alkalischer Lösung
Fritz Feigl,M. Steinhauser +1 more
TL;DR: Ammoniakalische Losungen von Hydroxylamin, Hydrazin, and Ascorbinsaure bewirken aus ammoniakalischen Losungs von Kupfer(II)-ferrocyanid und -ferricyanid die Abscheidung von KUpfer(I)-ferricianid bzw.

Prüfung auf reduzierende organische Verbindungen mit o-Dinitrobenzol in der Tüpfelanalyse
Fritz Feigl,L. Vokač +1 more
TL;DR: Organische Verbindungen, die in alkalischer Losung als Wasserstoffdonatoren fungieren, reduzieren alkoholisch-alkalische Losungen von o- and p-Dinitrobenzol zu blauvioletten bzw. orangefarbigen wasserloslichen Alkalisalzen von chinoiden Stickstoffsauren as mentioned in this paper.
Journal ArticleDOI
Differentiation of organic acids in spot test analysis
Fritz Feigl,Cecile Stark-Mayer +1 more
TL;DR: The detection of released halogen hydracid by means of indicator paper (or by demasking of silver ferrocyanide) makes possible a procedure for revealing the presence of effective organic acids.
Journal ArticleDOI
Contributions to organic spot test analysis
TL;DR: In this paper, the authors discuss the detection of hexamine through pyrohydrolytic splitting, which leads to formaldehyde and ammonia, and then use ammonium chloride to produce volatile aliphatic amines.
