PHYSICOCHEMICAL PROPERTIES OF WATER-1,4-BUTYLENE GLYCOL MIXTURES AND THEIR ELECTROLYTE-SOLUTIONS

Experimental data on density, viscosity, and dielectric constant of wa ter-1,4-butylene glycol mixtures at 15-55 degrees C as well as on dens ity of LiCl, NaCl, and KCl solutions (at m = 0.5 mole . kg(-1)) in the se mixtures and speeds of ultrasound propagation in these mixtures at 25 degrees C are presented. Excessive characteristics of the mixtures, partial molar volumes of components, and adiabatic compressibility of the solutions are calculated, and the dependences of these properties on the mixture composition, temperature, and nature of the electrolyt e are discussed.
