Lipase-Catalyzed Polycondensation in Water: A New Approach for Polyester Synthesis

Abstract: The lipase-catalyzed polycondensation of sebacic aid and 1,4-butanediol can be performed in a biphasic reaction system composed of an aqueous reaction phase and an organic extraction phase. The shift of the equilibrium to higher product yields can be realized by the integrated product removal (IPR). In this biphasic reaction system the product yield, molecular weight and polydispersity is depending on the partitioning of the substrates and the product between the phases. By the biphasic approach substrate inhi… Show more

“…By increasing the organic phase from 1 to 4, the product concentration raised from 47.8% to 71.6%, with an increase of 23.8%. Duwensee et al mentioned that a higher capacity of the organic phase leads to a higher driving force transfer due to a larger difference of its chemical potential in the two-phase system [19]. In biphasic systems, a high driving force for the product to pass into the organic phase leads to the higher yield for the n-hexan e Dich lorometh ane Aceton e TH F Cyclo hexa ne esterification.…”
