Abstract
Velocity of ultrasonic waves, as a function of temperature and concentration have been measured for four naphthalene halogen derivative solutions in supersaturated metastable regions, under conditions of continuous linear cooling and without stirring. The maximum undercooling (Delta) Tmax was evaluated as a difference between saturation temperature and the temperature of first precipitation detected by the change of ultrasonic velocity. It was found that for all the solutions in their metastable regions, ultrasonic velocity linearly increases with decreasing temperature at given concentration and that the first-order equations relating ultrasonic velocity with solutions concentration can satisfactorily be used to describe the data.
