Viscosity and thermodynamic characteristics of viscous flow of aqueous tetrabutylammonium nitrate solutions

The authors have determined viscosities of aqueous solutions of tetrabutylammonium nitrate, in concentrations from 0. 009 to 7. 3 moles per 1000 g H//2O at 10 to 50 C with the aid of ciscosimeters of the VPZh- 1 type, giving efflux times not less than 200 sec. The thermodynamic functions of activation of viscous flow were calculated from the experimental viscosity data. Results indicate that the tetrabutylammonium cation has a considerable ordering effect on the primary structure of water.
