Data on the extraction of benzoic, salicylic and sulfosalicylic acids from dilute solutions using PEG-based aqueous two-phase systems

The use of green chemistry principles in the extraction of aromatic acids from dilute aqueous solutions has been considered. The extraction of a number of aromatic acids important for the food and pharmaceutical industries in heterogeneous systems based on poly(ethylene) glycol 1500 (PEG-1500) has b...

description The use of green chemistry principles in the extraction of aromatic acids from dilute aqueous solutions has been considered. The extraction of a number of aromatic acids important for the food and pharmaceutical industries in heterogeneous systems based on poly(ethylene) glycol 1500 (PEG-1500) has been studied for the first time. This research presents a data of the quantitative characteristics of the extraction of benzoic, salicylic and sulfosalicylic acids using a PEG-1500 (15 wt %)/Na(2)SO(4) (9 wt %) aqueous two-phase system under various conditions (temperature and рН). The effect of various phase-forming salts (Na(2)CO(3), (NH(4))(2)SO(4), and (NH(4))(2)HPO(4)) in a PEG-1500-based aqueous two-phase system on the extraction of aromatic acids has been found. For salicylic and sulfosalicylic acids, distribution coefficients when using (NH(4))(2)HPO(4) have been obtained that considerably exceed values for conventional water–organic solvent systems.
