Abstract
1. Separation of nitrogen-containing bases, chiefly pyridine bases, was conducted by the method of gas-liquid chromatography. A good stationary phase for the separation of low-and high-boiling pyridine bases is polyethylene glycol adipate, while alkali-treated diatomite brick and sodium chloride can be used as the solid carrier. 2. The relative retainable volumes of the pyridine bases were determined at 150–210° (internal standard pyridine). A linear relationship exists between the logarithm of the relative retainable volume and the boiling point (and the number of carbon atoms in the side chain for alkylpyridyl ketones), permitting the identification of unknown substances. 3. Effects related to the interaction of nitrogen-containing compounds with the stationary phase and solid carrier were discussed. 4. A quantitative analysis of the chromatographed nitrogen-containing compounds was carried out. The coefficients of proportionality of the areas of the peaks to the % by weight were found.
