ON SOME SPECIFIC FEATURES OF HIGH-FREQUENCY SOUND DISPERSION IN A SOLUTION WITH A PECULIAR POINT
Keywords:
Aqueous solutions, Methylpyridines, Thermodynamic stability, Peculiar point, Structural transformationsAbstract
Aqueous solutions of methyl derivatives of pyridine with concentrations 0.06 to 0.08 mole fraction (MF) at the normal air pressure and temperature t0 ≈ 70oC have a minimum of thermodynamic stability [1] (a peculiar point in the temperature−concentration phase diagram) and thus are convenient for studying structural transformations in the vicinity of the peculiar point.
