Online‐Analyse von enzymatischen Polykondensationsreaktionen in Blasensäulenreaktoren mittels ATR‐FTIR‐Spektroskopie [Online analysis of enzymatic polycondensation reactions in bubble column reactors by means of ATR-FTIR spectroscopy] Link: Autor/in: Verlag/Körperschaft: Hamburg University of Technology Erscheinungsjahr: 2013 Medientyp: Text Schlagworte: Chemometrics Lipase Online analysis Polyester Polymerization 570: Biowissenschaften, Biologie 600: Technik 620: Ingenieurwissenschaften Beschreibung: The enzyme catalyzed polycondensation of 1,3-propanediol and 9-((Z)-non-3-enyl)-10-octylnonadecane diacid was carried out in a bubble column reactor. A conversion of 94 % was achieved within 50 h. A chemometric model was developed using infrared spectra collected via FT-IR combined with attenuated total reflectance probe. Root mean square errors of cross validation of the model for conversion and molecular weight were 2.14 % and 319 g mol -1, respectively. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
