A mathematical model of the evaporative cooling of binary drops in a flow reactor, accounting for the latent-heat liberation as a result of the phase transformation of the binary-drop components in the process of their condensation, the inverse processes of evaporation of these components, and the latent-heat liberation in the process of dissolution of one of the binary-drop components, has been developed. The numerical calculations were carried out for diluted ammonia spirits. It is shown that the evaporative cooling of binary drops in a flow reactor can be controlled by varying the compositions of the gas mixture and the solution and the ratio between their flow rates, and that the rate of cooling of drops can reach 2•105 K/sec.
