The sign inversion of the derivative of the adiabatic compressibility with respect to the concentration dBS(x)/dx and temperature dBS(t)/dt is observed. In the temperature-concentration phase diagram, the inversion points determine the lines of transition from the solution structure characterized by a nondisturbed continuous network of hydrogen bonds to the disturbed one, and, further, to the structure with fragmentary network.</p>}, number={9}, journal={Ukrainian Journal of Physics}, author={Sabirov, L.
