Abstract:	Excess volumesV ^E, excess viscosities ^E, 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 forV ⁴ and negative for both ^E andG ^E for all mixtures over the entire composition range.

Keywords:	activation energy binare mixtures free energy I-bromo-methypropane butanols viscosity excess volume
