The article presents the results of an experimental study of the phase behavior of the binary mixture «freon R404A-acetone»» carried out at temperatures of 356.15 K, 372.15 K and 392.15 K. I—II type of phase behavior according to the Williams classification is established. The article presents the results of a study of the supercritical fluid extraction process as applied to the problem of extracting acetone from its aqueous solution of 3.5% and 10 % concentration. In the process carried out at a temperature of 356.15 K (83 °C), an increase in the efficiency of the extraction process was established as the pressure approaches its critical value for the designated binary system.
