Abstract

Esterifikacije katalizirane lipazama jedne su od industrijski najznačajnijih kemijskih reakcija. Tradicionalno se ove reakcije odvijaju u organskim otapalima od kojih je većina ekološki neprihvatljiva zbog hlapljivosti i toksičnosti. Stoga, pokušavaju se pronaći nova rješenja kako bi enzimi koji kataliziraju ove reakcije bili visoko aktivni i stabilni u drugim, ekološki prihvatljivijim medijima. Ovaj rad razmatra upotrebu eutektičnih otapala, otapala nove generacije, kao učinkovitog medija za odvijanje Candida antarctica lipazom B katalizirane sinteze butil-acetata, kratkolančanog estera od industrijskog značaja, u kolinijevom eutektičnom otapalu sa različitim sadržajem vode.

Abstract (english)

Lipase-catalyzed esterifcations are one of the most important chemical reactions of industrial matter. Traditionally, these reactions are performed in organic solvents which are toxical and volatile. Thus, new approaches are being established to achieve high enzyme activity and stability in green solvents. This work examines the use of deep eutectic solvents, new generation solvents, as an efficient medium for Candida antarctica lipase B-catalyzed synthesis of butyl-acetat, short-chained industrially important ester, in cholinium based eutectic solvent with different water content
