Abstract

The formation of uni-, bi-, and trivalent metal ion dodecyl benzene sulphonate (DBS) precipitates was investigated using light scattering, low angle X-ray diffraction and polarizing microscopy at 293 K. The thermodynamic equilibrium constants were calculated, improving some of our previous experimental results and applying a fitting program to the theoretical curve for association and solubility product equilibrium involving ionic strengths. The appearene of liquid crystals formed in a particular precipitation region is characterized by relationships of the reacting components. The question of the structural model of the metal ion — DBS liquid crystalline mesophase remains to be solved in future investigations.

Lecture given at the 31th Conference of the Kolloid Gesellschaft, Bayreuth October 11–14, 1983.
