THE RESEARCH OF THE COLLOIDAL AND CHEMICAL PROPERTIES OF THE MIXTURES OF SURFACTANTS
The aim of the research is the assessment of behaviour of the binary mixtures of the surface-active substances which are produced in Ukraine and Taiwan LAS 80 / Omero 16, LAS 80 / Tween 80, the detection of the synergetic and antagonistic effects in these mixtures. The optimal relations of the components for the textile chemicals and effective technological processes have been proposed. The process of the formation of micelles in a mixtures of anionic and nonionic surfactants has been studied, the assessment and the analysis of intermolecular interaction in solutions of surfactants with application of the theory of the regular solutions and model of the pseudophase division has been carried out. A synergism in the solutions of surfactants at the molar concentration of anionic surfactant more than 20 % in the mixtures with nonionic surfactants has been proved on the basis of the analysis of the obtained experimental data of the critical concentration of micelleformation, which indicates a negative deviation from ideal behaviour of the solutions.
