Primary and secondary amines can be directly separated as 4'-nitroazobenzene-+carboxamides by gas-liquid chromatography. Using silicone grease as a liquid phase and a constant temperature of z70Β°, the separation was performed with derivatives of primary and secondary aliphatic, alicyclic, and aroma

Fluorescence induced by U.V. radiation will appear as light bands on the print, provided the energy thus emitted is higher than that reflected by the background.

The authors have studied extensively the thin-layer chromatographic and electrophoretic behaviour of primary aromatic amines on weak ion exchangers such as alginic acid and carboxymethylcellulose. The eluents were solutions of organic and inorganic acids, water, buffer solutions and aqueous organic
Thirteen derivatives of pyrimidine were prepared as potential medicinal agents by the reaction of 2amino-4-chloro-6-methylpyrimidine with primary and secondary amines in the absence of a solvent. Six of the derivatives are piperazinylpyrimidines. The compounds prepared in this work may prove to be e
