摘要

A second attempt has been made to investigate intermolecular hydrogen-bonding interactions among adsorbed analyte molecules (so-called lateral interactions), and their impact on the retention process. In this work, three compounds from a homologous series of dicarboxylic acids were selected as the test ana-lytes. To this effect, a novel model was investigated.The quantitative validity of this novel model was checked experimentally with three dicarboxylic acids (succinic, adipic, and suberic) as test solutes. TLC was performed with cellulose powder and 1,4-dioxane, respectively, as stationary and mobile phases. The results obtained, fully confirmed the practical utility of our approach.The traditional definition of the R_F coefficient was re-examined and its irrelevance to analytes participating in lateral interactions was demonstrated, as was the use of densitograms (rather than flat overall pictures of TLC chromatograms).
