- Аннотация: The chromatographic behavior of nitrobenzodiazole derivatives of primary and secondary n-alkylamines was studied as a function of the molecular structure and the composition of the mobile phase under conditions of reversed-phase high-performance liquid chromatography. The influence of these factors on the selectivity of separation and the specific and nonspecific components of retention was determined. Correlations between coefficients describing different components of retention, the composition of the mobile phase, and the length of the organic radical in the amine molecule were revealed. The components of a complex commercial mixture of primary aliphatic amines used as a flotation agent were identified, and the quantitative composition of the mixture was determined. © 1997 MAEe Cyrillic signK Hayκa/Interperiodica Publishing.
