Separation of Pyridine Mono-Carboxylic Acids on Paper Chromatograms

Nature, 1956
CHEMICAL methods using cyanogen bromide and aromatic amines1–3 (Konig reaction) and an acid-indicator4 for the detection of pyridine carboxylic acids on paper chromatograms have been reported. But the toxic character of cyanogen bromide causes difficulty; and it has been observed that good spots with acid-indicator are often not produced, particularly ...

The preparation of pyridine‐4‐carboxylic acid and of piperidine‐4‐carboxylic acid by catalytic reduction of 2,6‐dichloropyridine‐4‐carboxylic acid

Recueil des Travaux Chimiques des Pays-Bas, 1944
Abstract2,6‐Dichloropyridine‐4‐carboxylic acid (II) is converted by catalytic reduction with nickel in alkaline medium into pyridine‐carboxylic acid (III). If the catalytic reduction ofIIis carried out in glacial acetic acid and with platinum (Adams) as a catalyst, piperidine‐4‐carboxylic acid (IV) is formed in one operation which substance is also ...

Silver complexes of pyridine carboxylic acids and of 8-hydroxyquinoline

Journal of Inorganic and Nuclear Chemistry, 1974
Abstract The 8-hydroxyquinoline and pyridine carboxylic acid complexes of silver have been reinvestigated using ESCA, i.r. and u.v. spectroscopy, and through chemical properties in some cases. Many of the complexes do not have the simple 1:1 or 1:2 metal-ligand ratios previously assigned.
