Key words: water-soluble polymers, supercritical carbon dioxide, extraction, recovery, benzoic acid, caffeine, thiophene

This work presents the experimental study results of the benzoic acid, caffeine, and thiophene recovery from polymer phases by supercritical fluid extraction. The extraction efficiency dependences of the studied compounds on the conditions of fluid existence — temperature, and pressure were obtained. It has been shown that benzoic acid, caffeine, and thiophene are extracted in one step into supercritical CO² with the extraction degree of 43, 48.5, and 84 % respectively.
