Zusammenfassung:According to experimental data on the density of polyol solutions and the propagation velocity of ultrasonic waves in them, the adiabatic compressibilities of the aqueous solutions of erythritol, xylitol, sorbitol, and mannitol are calculated. For all examined solutions, the temperature dependence of the adiabatic compressibility is found to pass through a minimum. As the polyol concentration in water increases, the minimum of the adiabatic compressibility shifts toward lower temperatures. The temperature values corresponding to the minimum of the molar adiabatic compressibility are calculated. The concentration dependences of this parameter are shown to be linear. The presence of a special point for the studied aqueous solutions of polyols is established.
