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.
