Titel
Enzymatic esterification with continuous product removal
Abstract
For the enzymatic production of natural flavour esters lipase was used. With the in-line connection of pervaporation units to the esterification process an integrated system is presently under investigation. Preliminary experiments were carried out with acetic acid and ethanol as initial components, the solvent of the esterification was the alcohol itself. For the continuous separation of the products ethyl acetate and water, pervaporation and adsorption, respectively, were examined in order to avoid product inhibition and promote the ester production. Recently, experiments were carried out to investigate water removal by pervaporation.
