    Long-term aperiodic oscillatory phase transitions of gas – solution and solution – crystal have been reproduced experimentally in the ensemble of aqueous droplets with a dissolved component. The new observations can simplify the dynamic model of phase transitions of the oscillating mode considered before. It reduces the number of independent variables and the need to consider the formation of metastable phases. The model establishes a relation between the speed and direction of solvent flow in the gas and the vapor pressure in the drop neighborhood, temperature of the drop, the rate of change in temperature, the rate of change in volumes of the drop and the crystal. The analysis has revealed that the presence of crystalline phases in the system causes at least two singularities (bifurcations) of the chemical potential of the volatile component with respect to its quantities in the drop.
