Abstract

Viscosity and conductance measurements in cetyldimethylbenzylammonium chloride solutions in molten pyridinium chloride are in agreement with other studies that indicate that micellization commences at 0.06-0.07m at 155°. Effective molal volumes, bulk viscosities, and equivalent conductivities for this system and a comparison system (anilinium chloride as solute), have been calculated. The data suggest that around 0.12m the micelles are stabilized in a size distribution comprised mainly of asymmetric micelles. Molten pyridinium chloride behaves ultrasonically as an associated liquid. The densities and viscosities of 0.5M KCl sucrose solutions (25-40% sucrose) are also supplied as calibration data for electroviscometers in the range 2-5 cP.
