The Viscous Properties of Diols. IV. 1,2-and 1,4-Butanediol in Butanols Solutions

The paper presents the results of viscosity measurements performed on 1,2-and 1,4-butanediol in n-, s-and t-butanol solutions in the whole range of concentration, at different temperatures. The activation energy for viscous flow of the solutions and the viscosity excess were determined. The excess shows a peculiar behavior for 1,4-butanediol in t-butanol solutions
