Description
Summary:The influence of supramolecular self-organizing surfactant-based media on the condensation reactions of some carbonyl compounds with arylamines (formation of Schiff bases, hydrazones and naphthoquinones) was studied by conductometry, light-scattering spectroscopy, molecular spectroscopy, and tensiometry. The function of surfactants was proved to differ, depending on its concentration: below the critical micelle concentration ( CMC ) they acted as a reagent, while at higher concentrations, they demonstrated properties of reaction media. The effects observed were analyzed, regarding their potency to govern indicatory reactions in the systems specified, reduce limits of detection for the determination of carbonyl and amino-compounds, refine analytical parameters of the condensation reactions, and broaden the area of their application.
