摘要
The results of a study of physicochemical properties (density, viscosity, refractive index, contraction, and surface tension) of water-alcohol (water-ethanol, water-propanol, and water-isopropanol) and alcohol-alcohol (propanol-butanol) mixtures are presented. The ratios of water and alcohol corresponding to the maxima of the viscosity and contraction of the mixtures are determined. A nonlinear character of dependences of the density and refractive index for water-alcohol mixtures versus their composition is demonstrated.
