ABSTRACT
The densities and viscosities of 1,1?-(pentane-1,5-diyl)-bis(pyridinium) dibromide in ethanol + water have been determined experimentally at temperatures from (293.15 to 344.15) K. The density and viscosity data were fitted by the Vogel-Tamman-Fulcher equation. The adjustable parameters and standard deviations are obtained.
