Abstract
Razvoj zelenih otapala je važan zadatak za industriju, pa se stoga se u posljednje vrijeme intenzivno istražuju eutektična otapala zbog njihovih poželjnih karakteristika kao što su niska toksičnost i biorazgradivost. Eutektična otapala zbog mogućnost prilagodbe njihovih svojstava odabirom početnih sirovina, privukla su pozornost u sintetskoj kemiji i biokatalizi, separacijskim postupcima ali i kao medij za ekstrakciju prirodnih spojeva. Prilikom ekstrakcije fenolnih spojeva iz pokožice grožđa, od pet testiranih eutektičnih otapala, najučinkovitije se pokazalo ono sastavljeno od kolin klorida i oksalne kiseline s udjelom vode od 25 %. Navedeno eutektično otapalo pokazalo se učinkovitije i od klasične metode primjenom zakiseljenog metanola. Rezultati istraživanja utvrdili su mogućnost zamjene klasičnih organskih otapala eutektičnim otapalima kod ekstrakcije antocijana iz pokožice grožđa.
Abstract (english)
Developing new green solvents is one of the most important tasks for industry. Lately, deep eutectic solvents have been researched due to their desirable characteristics like low toxcity and biodegrability. Deep Eutectic Solevents (DES), because of their adjustability, are widely used in synthetic chemistry and biocathalisis but also as extraction media for phenolic compounds. Among tested, DES made of choline chloride and oxal acid (with 25% of water in their content) showed the best performance in extraction of phenolic compounds from grape skin. It also showed better performance in comparison to conventional solvents. Results of this experiment showed that conventional solvents for extraction of phenolic compounds can be replaced with DESs.
