Abstract

Viscosity and density measurements at concentration range (0.0040-0.1661mole/L) for the
tetrabutylammonium bromide (TBABr) solutions in methanol and ethanol at various temperatures
(298.15, 303.15 and 308.15 K) are reported. The viscosity A and B coefficient was calculated from
the Jones–Dole equation and found to be decreased from methanol to ethanol. The Gibbs free
energy of viscons flow of (TBABr) solutions in methanol and ethanol we’re calculated from
experimental viscosity measurements using Eyring equation. The apparent molal volumes   for
these solutions at different temperatures we’re also obtained from experimental density
measurements.
