A New Mathematical Model for the Characterization of Viscosity Variations in the Aqueous Solutions of Monoalcohols and Polyalcohols

Abstract This study aims to investigate the viscosity of binary mixtures water with different monoalcohols and polyalcohols. The values methanol, ethanol, 1-propanol, 2-propanol were taken from a published by Herraez Belda (2004). for ethylene glycol, glycerin, sorbitol measured using similar protocol. mixture is expressed as function molar fraction alcohols that ranges 0 (pure solvent, in this case) 1 solute). To represent these mixtures, new variable, Φ, was introduced. representation provides function, η = f(Φ), has an exponential nature, which excellent correlation coefficients are achieved only one coefficient or two Additionally, variable Φ highlights possible critical points, where physicochemical interactions occur between components mixture.
