Superficially Porous Particle Based Hydroxypropyl‐β‐cyclodextrin Stationary Phase for High‐Efficiency Enantiomeric Separations
Authors: Spudeit Daniel A. , Breitbach Zachary S. , Dolzan Maressa D. , Micke Gustavo A. , Armstrong Daniel W. 
Published: September 2015

AbstractA superficially porous particle (SPP)‐based hydroxypropyl‐β‐cyclodextrin (HPBCD) chiral stationary phase (CSP) was produced and its chromatographic performance was compared to both 5 µm and 3 µm fully porous particle (FPP)‐based CSPs. The relative surface coverage of the HPBCD chiral selector on each particle was approximately equal, which resulted in equivalent enantiomeric selectivity (α) values on each phase when constant mobile phase conditions were used. Under such conditions, the SPP column resulted in greatly reduced analysis times and three times greater efficiencies compared to the FPP columns. When higher flow rates were used, efficiency gains per analysis times were five times greater for the SPP column compared to the FPP‐based columns. When the mobile phases were altered to give similar analysis times on each column, resolution values were doubled for the SPP column. Finally, the novel SPP based HPBCD column proved to be stable for 500 injections under high flow rate (4.5 mL/min) and high pressure (400 bar) conditions used for an ultrafast (~45 sec) enantiomeric separation.

Direktsynthese von Bioethylen aus Weizenstroh
Authors: Steffien Doreen , Roßberg Christine , Kiehle Rica , Bremer Martina , Fischer Steffen , Bertau Martin 
Published: September 2015

AbstractDie Konversion von Lignocellulose in Ethylen führt zu einer bis zu dreimal höheren Wertschöpfung gegenüber Bioethanol. Voraussetzung ist der direkte Zugang zu Bioethylen ohne vorangehende Isolierung des Ethanols. Erreicht wurde dies durch eine Vorbehandlung von Weizenstroh mit Natronlauge. Bei der anschließenden simultanen Verzuckerung und Fermentation (SSF) mit dem Cellulasekomplex aus Penicillium verruculosum wurden bei Verwendung von Saccharomyces cerevisiae L13 Ethanolgehalte von ca. 13 Vol.‐% erreicht. Durch Strippen der Fermentationsbrühe mit N2 wurde ohne weitere Aufarbeitung und Reinigungsoperation am ZSM‐5‐Kontakt quantitativ Ethylen erhalten.
