The results of the study of crystallization processes izogidricheskoy organic products and water-soluble impurities from the crystallization of a change in the properties of the solvent (salting out). The data on the equilibrium concentrations of components and impurities of the target substance in the temperature range from 4 to 35 ºC in suspensions of organic substances such as R-salt, p-phenylenediamine, Mr. Salt, DL-acid Belophor CD-2, nitrodiazoksid. The effect of cooling rate of the solution, and the introduction of salting out agent on the size of the formed crystals of the target substances and contaminants. Recommendations for changes in process parameters selection (crystallization) on the basis of data on the equilibrium concentrations of components, and the effect of cooling rate and the introduction of salting out agent on the formation conditions of the maximum impact on the growth kinetics of particles and impurities of the target substance. Change the final solution temperature, cooling rate and feed salting out agent will adjust the dimensions of the particles of the desired product and impurities.
