Simulation Study of Dissociation Extraction in Separation of 3-picoline and 4-picoline

The two phases and multi-component system after the addition of the extractant was analyzed in detail, and a model was established by which the number of equilibrium stages for a given separated goal may be determined with stage-to-stage calculation. The experimental conditions were optimized by the results of the orthogonal test, and along with the model the required stages to obtain the products with purity ges 99% were 14, toward the mixture which the content of 3-picoline is higher than that of 4-picoline (y
