Abstract:
Unspecific peroxygenase (EC 1.11.2.1) represents a group of secreted hemethiolate proteins that are capable of catalyzing the selective mono-oxygenation of diverse organic compounds using only H2O2 as a cosubstrate. In this study, the peroxygenase from Agrocybe aegerita (AaeUPO) was found to catalyze the hydroxylation of various linear (e.g n-hexane), branched (e.g. 2,3-dimethylbutane) and cyclic alkanes (e.g. cyclohexane). The size of n-alkane substrates converted by AaeUPO ranged from gaseous propane (C3) to n-hexadecane (C16). They were mono-hydroxylated mainly at the C2 and C3 position, rather than at the terminal carbon, and the corresponding ketones were formed as a result of overoxidation. In addition, a number of alkenes were epoxidized by AaeUPO, including linear terminal (e.g. 1-heptene), branched (2-methyl-2-butene) and cyclic alkenes (e.g. cyclopentene), as well as linear and cyclic dienes (buta-1,3-diene, cyclohexa-1,4-diene). Furthermore, the conversion of terminal alkynes (e.g. 1- octyne) gave the corresponding 1-alkyn-3-ol in low yield. Some of the reactions proceeded with complete regioselectivity and - in the case of linear alkanes, terminal linear alkenes and alkynes - with moderate to high stereoselectivity. The conversion of n-octane gave (R)-3-octanol with 99% enantiomeric excess (ee) and the preponderance of the (S)-enantiomer reached up to 72% ee of the epoxide product for the conversion of 1-heptene. Catalytic efficiencies (kcat/ Km) determined for the hydroxylation and respectively epoxidation of the model compounds cyclohexane and 2-methyl-2-butene were 2.0 × 103 M-1 s-1 and 2.5 × 105 M−1 s−1. The results obtained in the deuterium isotope effect experiment with semideuterated n-hexane and the radical clock experiment with norcarane clearly demonstrated that the hydroxylation of alkanes proceeds via hydrogen abstraction, the formation of a substrate radical and a subsequent oxygen rebound mechanism. Moreover, stopped-flow experiments and substrate kinetics proved the involvement of a porphyrin radical cation species (compound I; AaeUPO-I) as reactive intermediate in the catalytic cycle of AaeUPO, similar to other hemethiolate enzymes (e.g. cytochrome P450 monooxygenases, P450s)
Die Gruppe der Unspezifischen Peroxygenasen (EC 1.11.2.1) umfasst extrazelluläre Häm-Thiolat-Enzyme, die mittels H2O2 als Cosubstrat die selektive Monooxygenierung unterschiedlicher organischer Verbindungen katalysieren. In der vorliegenden Arbeit konnte gezeigt werden, dass die von Agrocybe aegerita sekretierte Peroxygenase (AaeUPO) verschiedene lineare (z. B. n-Hexan), verzweigte (z. B. 2,3-Dimethylbutan) und zyklische Alkane (z. B. Cyclohexan) hydroxyliert. Die Größe der von der AaeUPO umgesetzten Substrate reichte vom gasförmigen Propan (C3) bis hin zu n-Hexadekan (C16). Die Alkane wurden bevorzugt am zweiten und dritten Kohlenstoffatom (C2 und C3) hydroxyliert; eine Hydroxylierung am terminalen Kohlenstoff konnte nur vereinzelt und in geringem Umfang beobachtet werden. Die Überoxidationen der primär gebildeten, sekundären Alkohole führte außerdem zur Entstehung der entsprechenden Ketonderivate. Darüber hinaus wurde eine Vielzahl linearer terminaler (z. B. 1-Hepten), verzweigter (z. B. 2-Methyl-2-Buten) und zyklischer Alkene (z. B. Cyclopenten) sowie linearer und zyklischer Diene (1,3-Butadien, 1,4-Cyclohexadien) durch die AaeUPO epoxidiert. Die Umsetzung terminaler Alkine (z. B. 1-Octin) führte zur Entstehung der jeweiligen 1-Alkin-3-ole. Manche dieser Reaktionen verliefen ausgeprägt regioselektiv und, im Falle der linearen Alkane sowie der linearen terminalen Alkene und Alkine, mit mittlerer bis hoher Stereoselektivität. So ergab beispielsweise die Umsetzung von n-Octan einen Enantiomerenüberschuss größer 99% für (R)-3-Octanol; die Epoxidierung von 1-Hepten lieferte einen Enatiomeerenüberschuss (ee) von bis zu 72% für das (S)-Enantiomer. Die katalytischen Effizienzen, die für die Hydroxylierung bzw. Epoxidierung der Modellverbindungen Cyclohexan und 2-Methyl-2-Buten ermittelt wurden, betragen 2.0 × 103 M-1 s-1 und 2.5 × 105 M−1 s−1. Der ausgeprägte Deuterium-Isotopen-Effekt, der im Zuge der Umsetzung von semideuteriertem n-Hexan beobachtet wurde sowie die Ergebnisse des Radical-Clock-Experiments mit Norcarane als Substrat bestätigten, dass die Hydroxylierung von Alkanen über Wasserstoffabstraktion, die Bildung eines Substratradikals und anschließende direkte Sauerstoffrückbindung verläuft. Die Stopped-Flow-Experimente belegen zudem das Auftreten eines Porphyrin-Kationradikal-Intermediates (Compound I; AaeUPO-I) im katalytischen Zyklus der AaeUPO (vergleichbar mit dem reaktiven Intermediat der P450-Monooxygenasen)

Abstract:
Es ist in dieser Arbeit gelungen, starre Oligospiroketal(OSK)-Stäbe als Grundbausteine für komplexe 2D- und 3D-Systeme zu verwenden. Dazu wurde ein difunktionalisierter starrer Stab synthetisiert, der mit seines Gleichen und anderen verzweigten Funktionalisierungseinheiten in Azid-Alkin-Klickreaktionen eingesetzt wurde. An zwei über Klickreaktion verknüpften OSK-Stäben konnten mittels theoretischer Berechnungen Aussagen über die neuartige Bimodalität der Konformation getroffen werden. Es wurde dafür der Begriff Gelenkstab eingeführt, da die Moleküle um ein Gelenk gedreht sowohl gestreckt als auch geknickt vorliegen können. Aufbauend auf diesen Erkenntnissen konnte gezeigt werden, dass nicht nur gezielt große Polymere aus bis zu vier OSK-Stäben synthetisiert werden können, sondern es auch möglich ist, durch gezielte Änderung von Reaktionsbedingungen der Klickreaktion auch Cyclen aus starren OSK-Stäben herzustellen. Die neu entwickelte Substanzklasse der Gelenkstäbe wurde im Hinblick auf die Steuerung des vorliegenden Gleichgewichts zwischen geknicktem und gestrecktem Gelenkstab hin untersucht. Dafür wurde der Gelenkstab mit Pyrenylresten in terminaler Position versehen. Es wurde durch Fluoreszenzmessungen festgestellt, dass das Gleichgewicht z. B. durch die Temperatur oder die Wahl des Lösungsmittels beeinflussbar ist. Für vielfache Anwendungen wurde eine vereinfachte Synthesestrategie gefunden, mit der eine beliebige Funktionalisierung in nur einem Syntheseschritt erreicht werden konnte. Es konnten photoaktive Gelenkstäbe synthetisiert werden, die gezielt zur intramolekularen Dimerisierung geführt werden konnten. Zusätzlich wurde durch Aminosäuren ein Verknüpfungselement am Ende der Gelenkstäbe gefunden, das eine stereoselektive Synthese von Mehrfachfunktionalisierungen zulässt. Die Synthese der komplexen Gelenkstäbe wurde als ein neuartiges Gebiet aufgezeigt und bietet ein breites Forschungspotential für weitere Anwendungen z. B. in der Biologie (als molekulare Schalter für Ionentransporte) und in der Materialchemie (als Ladungs- oder Energietransporteure).
In this dissertation the use of rigid Oligospiroketal (OSK)-rods as basic model for 2D- and 3D-systems was shown. For that purpose a bifunctionalized rigid rod was synthesized and was used in Azide-Alkine-clickreaction with itself and with other branched functionalized units. By theoretical calculations a statement about the novel bimodulation of the conformation of two OSK-rods which are linked by a clickreaction could be made. “Articulated rod” was introduced as new term, because the molecules could exist elongated or buckled. Based on this knowledge it became apparent that not only the size selective synthesis of polymers by using up to four OSK-rods is possible but also cycles with OSK-rods by using different click-reaction conditions can be synthesized. The newly developed group of “articulated rod” substances was examined regarding the equilibrium between buckled and elongated “articulated rod”. That for the articulated rod was functionalized with pyrenyl moieties in terminal position. By fluorescence measurements of these rods it could be shown that the equilibration is influenced by different temperatures and different solvents. For multiple applications a simplified strategy for synthesis with a wide range of functionalization in only one step of synthesis could be achieved. Photoactive articulated rods were synthesized, that could be selectively intramolecular dimerized. Additionally, amino acids were introduced as linker at the end of a articulated rod. By this a stereoselective synthesis of multiple functionaliations is possible. By the synthesis of complex articulated rods a novel field of research was found. There is a wide potential of research for more applications for example in biology (as molecular switch for transportation of ions) and in materials chemistry (as transporter for charge or energy).

Abstract:
Gegenstand der vorliegenden Arbeit sind Versuche zur Synthese von 1-Azido-1 alkinen (Ethinylaziden). Diese instabilen Verbindungen zersetzen sich leicht unter Stickstoffabspaltung zu hochreaktiven Carbenen, welche mit verschiedenen Reagenzien, explizit Tolan, Cyclooctin, DMSO sowie DMF, abgefangen werden konnten. Obwohl eine direkte spektroskopische Beobachtung der Titelverbindungen mittels Tieftemperatur-NMR-Spektroskopie nicht verwirklicht werden konnte, gelang der eindeutige Nachweis von Ethinylaziden via deren 1,3-dipolarer Cycloaddition mit dem hochgespannten cyclischen Alkin Cyclooctin. Als Strategie für die Synthese der Titelverbindungen wurden sowohl Substitutionsreaktionen ausgehend von (Chlorethinyl)aromaten als auch Eliminierungsreaktionen ausgehend von substituierten Vinylaziden herangezogen. Es konnten zahlreiche Sulfoxonium-Ylide sowie alpha-Oxocarbonsäureamide als eindeutige Folgeprodukte der Titelverbindungen isoliert und vollständig – größtenteils sogar anhand von Röntgeneinkristallstrukturanalysen – charakterisiert werden.

Abstract:
The production of carbon-neutral liquid fuels from renewable biomass has attracted worldwide interest in an age of depletion of fossil fuel reserves and pollutions caused by utilization of fossil petroleum. Currently, commercial bio-oil production technologies include bio-ethanol, bio-diesel and pyrolysis bio-oil. But, these bio-oils mainly consist of alcohols and aromatic chemicals rather than alkanes of the main components of gasoline and diesel. Direct utilization of these bio-oils can corrode car engines as well as emitting large unburned hydrocarbons particles through automotive combustion system. Therefore, in this study, catalytic hydrothermal conversion (CHTC) of glucose to alkanes in a single batch reactor was investigated with respect to effects of conversion parameters such as initial pressure of process gas H2, pH level of aqueous solution and catalysts on alkane yields and compositions. Results showed that the highest alkane yield of 21.6% (based on the mol of the input glucose) was obtained at 265 °C, with 300 psi of H2 process gas, 0.5 g catalyst of 1w%. Pt/Al2O3 and a residence time of 15 h. The alkane yield was significantly influenced by the initial pressure of H2, which increased with increasing H2 pressure. On the other hand, the alkane yields first increased and then decreased with pH levels. Also, more alkanes were produced by Pt/Al2O3 than Pd/Al2O3. Regarding alkane compositions, high initial pressure of H2 favored the production of relatively heavy C3–4 alkanes. With 300 psi of initial H2, C3H8 and C4H10 accounted for 75% of the total produced alkanes. All of the experimental data in this study lead to one conclusion that petroleum alkanes can be directly produced from glucose.

Abstract:
Pyrolysis experiments of isobutane, isobutylene, and 1-butene were performed over a temperature range of 550–750 °C and a pressure of ∼ 0.8 atm. The residence time was ∼ 5 s. The fuel conversion and product selectivity were analyzed at these temperatures. The pyrolysis experiments were performed to simulate the gas phase chemistry that occurs in the anode channel of a solid-oxide fuel cell. The experimental results confirm that molecular structure has a substantial impact on pyrolysis kinetics. The experimental data show considerable amounts of C5 and higher species (∼2.8 mole % with isobutane at 750 °C, ∼7.5 mole % with isobutylene at 737.5 °C, and ∼7.4 mole % with 1-butene at 700 °C). The C5+ species are likely deposit precursors. The results confirm that hydrocarbon gas phase kinetics have substantial impact on SOFC operation.

Abstract:
Alternative liquid fuels can contain hydrocarbons of different types and chain lengths and the fuel composition has an influence on combustion behavior. In this study, the influence of liquid single-component fuels on exhaust gas emissions of a gas turbine model combustor for swirl-stabilized spray flames was investigated under atmospheric pressure. The nozzle exhibited a dual-swirl geometry and a prefilming airblast atomizer. The spray was characterized by Phase Doppler Anemometry (PDA) and Mie scattering measurements and the flame CH* chemiluminescence was measured. Six single-component hydrocarbons were chosen: three linear alkanes (n-hexane, n-nonane, n-dodecane), one cyclic alkane (cyclohexane), one branched alkane (iso-octane) and one aromatic hydrocarbon (toluene). Kerosene Jet A-1 was used as a technical reference. Results show minor differences in CO emissions and significant differences in NOx emissions of the various fuels at comparable flow conditions and adiabatic flame temperatures. The measurements indicate a correlation between the nitric oxide emissions and the spray quality.

Abstract:
Alkanes such as methane, ethane, and propane make up a large portion of most natural gas fuels. Natural gas is the primary fuel used in industrial gas turbines for power generation. Because of this, a fundamental understanding of the physical characteristics such as the laminar flame speed is necessary. Most importantly, this information is needed at elevated pressures to have the most relevance to the gas turbine industry for engine design. This study includes experiments performed at elevated pressures, up to 10-atm initial pressure, and investigates the fuels in a pure form as well as in binary blends. Flame speed modeling was done using an improved version of the kinetics model that the authors have been developing over the past few years. Modeling was performed for a wide range of conditions, including elevated pressures. Experimental conditions include pure methane, pure ethane, 80/20 mixtures of methane/ethane, and 60/40 mixtures of methane/ethane at initial pressures of 1, 5, and 10 atm. Also included in this study are pure propane and 80/20 methane/propane mixtures at 1 and 5 atm. The laminar flame speed and Markstein Length measurements were obtained from a high-pressure flame speed facility using a constant-volume vessel. The facility includes optical access, a high-speed camera, a schlieren optical setup, a mixing manifold, and an isolated control room. The experiments were performed at room temperature, and the resulting images were analyzed using linear regression. The experimental and modeling results are presented and compared to previously published data. The data herein agree well with the published data. In addition, a hybrid correlation was created to perform a rigorous uncertainty analysis. This correlation gives the total uncertainty of the experiment with respect to the true value rather than reporting the standard deviation of a repeated experiment. Included in the data set are high-pressure results at conditions where in many cases for the single-component fuels few data existed and for the binary blends no data existed prior to this study. Overall, the agreement between the model and data is excellent.

Abstract:
The catalytic dehydrogenation reaction of isobutane to isobutylene is simulated in a commercial-scale heterogenous fixed bed reactor (FBR). The porous medium method in ANSYS Fluent combined with the reaction model capability was utilized to predict the flow behavior and species transport in a bed of spherical particles. Physical and material properties of a dehydrogenating catalyst of Chromium Oxide (Cr2O3) on Aluminum Oxide Support (Al2O3) were employed in the model. Several reaction models were implemented using a customized User-defined Function (UDF) subroutine. Simulation results were validated against literature data for a similar process. Good agreement was observed for the conversion of alkanes to alkenes within acceptable accuracy. It is concluded that the power-law model showed the least fit for the feed conversion and product selectivity compared to the other studied reaction models.

Abstract:
This paper presents a study of crevice corrosion and environmentally assisted cracking (EAC) mechanisms in UNS S32205 and S32304 which were cold drawn to tensile strengths of approximately 1300 MPa. The study utilized a combination of electrochemical methods and slow strain rate testing to evaluate EAC susceptibility. UNS S32205 was not susceptible to crevice corrosion in stranded geometries at Cl⁻ concentrations up to 1.0 M in alkaline and carbonated simulated concrete pore solutions. UNS S32304 did exhibit a reduction in corrosion resistance when tested in a stranded geometry. UNS S32205 and S32304 were not susceptible to stress corrosion cracking at Cl⁻ concentrations up to 0.5 M in alkaline and carbonated solutions but were susceptible to hydrogen embrittlement with cathodic overprotection.
