Interphase Distribution of Aromatic Acids in the Polyethylene Glycol-Sodium Sulfate-Water System.

Issues of application of “green chemistry” principles to the extraction and separation of components of liquid mixtures have been discussed. In particular, quantitative characteristics of the interphase distribution of a number of aromatic acids in extraction systems based on polyethylene glycol and sodium sulfate have been determined. It has been shown that these systems, which do not contain components that are toxic or pose a fire hazard, are promising for the effective extraction of aromatic acids from natural and technogenic products.
