Abstract: | Excess volumesVE, excess viscositiesE, and excess free energies of activation of flow G*E at 298.15 and 313.15 K are reported for binary mixtures of 1-bronw-2-methypropane and each of the alcoholic isomers of I-butanol. The results were obtained from density and viscosity measurements and show positive values forV4 and negative for bothE andG*E for all mixtures over the entire composition range. |
