Bb. Panda et al., APPARENT MOLAR VOLUME AND VISCOSITY OF N-ETHYLPYRIDINIUM IODIDE IN WATER, Bulletin of the Chemical Society of Japan, 69(2), 1996, pp. 301-303
The apparent molar volume and the viscosities of N-ethylpyridinium iod
ide in water at 25, 30, 35, and 40 degrees C are reported. The apparen
t molar volumes decrease with increasing temperature and obey Masson's
equation. The high values of phi(v)(o) and S-v indicate strong ion-i
on interactions in water. phi(v)(o) is linearly related to temperature
. The viscosity data were analyzed by the Jones-Dole equation. The B v
alues indicate greater solvation. The thermodynamic parameters of visc
ous flow and hydration number are discussed in terms of hydrophobic hy
dration and solvent-shared ion-pairs.
