Variations Of Excess Viscosities Of Alcohol-Water And Alcohol-Alcohol Mixtures With Temperature

[Full Text]



Dikko A. B., Ahmed A. D., Pascal T., Alkasim A.





ABSTRACT: The variation of excess viscosity of several liquid mixtures base on mole fractions with temperatures have been done by many researchers. In this paper, we employed volume by volume ratio of mixing and determined the excess viscosity of four different mixtures of methanol-water, ethanol-water, methanol-ethanol, and methanol-ethanol-water at 308.15 -343.15 K. We found that the excess viscosity of the mixtures generally decrease with increase in temperature and all the values show negativity, indicating lowest interaction.
