Advection‐dominated solar dynamo model with two‐cell meridional flow and a positive α ‐effect in the tachocline
Authors: Bonanno A. , Elstner D. , Belvedere G. 
Published: July 2006

AbstractMost probably the sunspot cycle period is ruled by a meridional flow located near the base of the convection zone (Hathaway et al. 2003). On the other hand, if the eddy diffusivity is low enough, dramatic modification of the standard α 2Ω ‐dynamo by the meridional flow are expected. In this paper we shall discuss the dependence of periods, dynamo numbers and the sign of the current helicity as a function of the magnetic Reynolds number for a double cell meridional circulation and for a positive α ‐effect at the base of the convection zone. The dynamo action occurs at lower latitudes and its location is at the interface between equatorward and poleward motions near the base of the convection zone. In spite of the complexity of the flow pattern, our simulations show that the resulting dynamo action reproduces several observed features of the solar cycle. (© 2006 WILEY‐VCH Verlag GmbH & Co.

Experimental and Theoretical Characterization of the Valence Isomerization of Bi‐2H‐azirin‐2‐yls to Diazabenzenes

Published: July 2006

Abstract3,4‐Diazidocyclobutenes 16 were prepared from the corresponding dihalides. Some of these diazides, such as parent compound 16 d and phenyl‐substituted derivatives 16 c,f, underwent spontaneous stereoselective electrocyclic ring opening below room temperature, whereas the tetraalkyl derivatives of 16 had to be heated to force the same reaction. In most cases, the resulting 1,4‐diazidobuta‐1,3‐dienes 8 were isolated to study their photochemical transformation into bi‐2H‐azirin‐2‐yls 9 via intermediate mono‐azirines 17. Except for starting materials with a low number of substituents such as 9 d and 9 f, title compounds 9 underwent a thermal valence isomerization which led exclusively to pyridazines 18 at surprisingly low temperatures. Based on quantum‐chemical calculations for the parent bi‐2H‐azirinyl‐2‐yl 9 d at the UB3LYP/6‐31+G(d) and MR‐MP2/TZV(2df,2p) levels, the valence isomerization process is best explained by simultaneous homolytic cleavage of both CN single bonds of 9 to generate energetically favorable N,N′ diradicals 26, which cyclize to 18. The theoretical studies indicate also that one stereoisomer of 9, namely, the rac compound, should undergo valence isomerization more easily than the other, which is in conformity with different rates of these rearrangement reactions found experimentally. For the tetramethyl‐bi‐2H‐azirin‐2‐yls 9 g, which are better models for the experimentally studied compounds, simultaneous homolytic cleavage of both CN single bonds is also predicted by the calculations, although the intermediate diradicals 26 g are significantly higher in energy than those of the parent system 9 d.

Keramische Schwämme – Anwendungspotenzial monolithischer Netzstrukturen als katalytische Packungen
Authors: Reitzmann A. , Patcas F. C. , Kraushaar‐Czarnetzki B. 
Published: July 2006

AbstractKeramische Schwämme, in der Literatur oft auch als Schäume oder „foams”︁ bezeichnet, bieten durch ihre hochporöse und allseitig fluiddurchlässige Struktur viel versprechende Voraussetzungen für den Einsatz als katalytische Packungen in Festbettreaktoren. Die hier zusammengefassten Ergebnisse aus der Fachliteratur zeigen, dass potenzielle Anwendungen insbesondere für Reaktionen bestehen, bei denen hohe Fluiddurchsätze gefordert sind, starke Wärmetönungen auftreten und/oder der Stofftransport die Kinetik beeinträchtigt. Durch keramische Schwammpackungen lassen sich offenbar die Vorzüge von Formkörperschüttungen und Wabenkörpern vereinen. Anders als bei diesen Festbetten gibt es bei Schwammpackungen noch große Defizite in der quantitativen Beschreibung von Fluiddynamik, Wärme‐ und Stofftransport. So soll dieser Beitrag auch den Forschungsbedarf aufzeigen, der notwendig ist, um belastbare quantitative Kriterien für einen zweckmäßigen Einsatz katalytischer Schwammpackungen ableiten zu können.
Selektivhydrierung von Citral in organischem Lösungsmittel, in ionischer Flüssigkeit und in Substanz
Authors: Steffan M. , Lucas M. , Brandner A. , Claus P. , Wollny M. , Oldenburg N. 
Published: July 2006

AbstractUntersucht wird das Katalysatorsystem Ag‐In/SiO2 auf seine Eignung zur Selektivhydrierung von Citral mit dem Ziel, die acyclischen, allylischen Terpenalkohole Geraniol/Nerol mit hoher Selektivität und Raum‐Zeit‐Ausbeute zu synthetisieren. Da Flüssigphasenhydrierungen häufig auch durch die Wahl des Lösungsmittels beeinflusst werden, ist außerdem von Interesse, in welcher Weise das Lösungsmittel insbesondere über seine Polarität und Wasserstofflöslichkeit die Aktivität und Selektivität von Katalysatoren bei der Hydrierung des α,β‐ungesättigten Aldehyds Citral beeinflusst.
Membranreaktoren für die katalytische Oxidation
Authors: Caro J. 
Published: July 2006

AbstractUnter dem Begriff der „Prozessintensivierung”︁ erfolgen momentan intensive F&E‐Bemühungen, um auf den Kenntnissen der chemischen Reaktionstechnik und der Transportvorgänge aufbauend die Effizienz chemischer Prozesse zu steigern. Die Kombination einer Membran mit einer katalysierten Reaktion in einem Membranreaktor ist eines der Konzepte eines multifunktionalen Reaktors. Bislang haben chemische Membranreaktoren für Einsatztemperaturen > 100 °C keinen Eingang in die industrielle Praxis gefunden. Für diesen Temperaturbereich müssen anorganische Membranen entwickelt werden. Das entsprechende Entwicklungsniveau ist jedoch noch gering, es existiert noch keine großtechnische Gastrennung auf Basis anorganischer Membranen. Es zeichnet sich aber ab, dass membranunterstützte Partialoxidationen und selektive Hydrierungen an der Schwelle ihrer technischen Etablierung stehen. In diesem Beitrag werden Konzepte, Membranmaterialien und geeignete Reaktionen für die katalytische Partialoxidation in Membranreaktoren vorgestellt.
