Аннотация
Liquid–liquid phase equilibrium for a new extraction system based on polyvinylpyrrolidone-3500 and sodium nitrate at 298.15, 313.15, and 333.15 K has been studied. Binodal data and phase diagrams with liquid–liquid tie lines have been presented. Mathematical modeling of phase equilibrium in the given system has been performed. New parameters for the UNIQUAC equation have been selected. The UNIQUAC model can be successfully used to describe phase equilibrium in the system. The results of this study can be used in the development of new extraction processes for the recovery of organic compounds.
