Book Description :

Recent advances in metabolic engineering have allowed for the production of a wide array of molecules via biocatalytic routes. The high selectivity of biocatalysis to remove functionality from biomass can be used to produce platform molecules that are suitable for subsequent upgrading over heterogeneous catalysts. Accordingly, the more robust continuous processing allowed by chemical catalysis could be leveraged to upgrade biologically-derived platform molecules to produce direct or functional replacements for petroleum products. This thesis discusses our progress in developing processes that utilize a combination of chemical and biological catalysis, and using the perspective of heterogeneous chemical catalysis we identify and address challenges associated with bridging the gap between the two catalytic approaches. Chapter 3 and Chapter 4 focus on the development of new chemistry that utilizes bio-catalytically-derived platform molecules to yield high-value biorenewable chemicals. In Chapter 3 we show that furylglycolic acid (FA), a pseudo-aromatic hydroxy-acid suitable for co-polymerization with lactic acid, can be produced from glucose via enzymatically derived cortalcerone using a combination of Brønsted and Lewis acid catalysts. Cortalcerone is first converted to furylglyoxal hydrate (FH) over a Brønsted acid site, and FH is subsequently converted to FA over a Lewis acid site. In Chapter 4, Triacetic acid lactone is demonstrated to be a versatile biorenewable molecule with potential as a platform chemical for the production of commercially valuable bifunctional chemical intermediates and end products, such as sorbic acid. In Chapter 8 we extend this chemistry to the upgrading of 4-hydroxycoumarin to produce high-value pharmaceutical building blocks. Chapter 5 demonstrates that supported Ni, Pt, and Pd catalysts used for liquid phase hydrogenation are inhibited by the biogenic impurities present in biologically-derived feedstocks used to produce high-value chemicals. This inhibition is addressed in Chapter 6, where we show that microenvironments formed around catalytic active sites mitigate catalyst deactivation by biogenic impurities present during production of biorenewable chemicals from biologically-derived species. Finally, in Chapter 7, we use transition state theory as applied to thermodynamically non-ideal systems to explore the origins of the improved stability and activity that we observed in Chapter 6. We conclude with a discussion of future directions.

Book Description :

Rock weathering processes are fundamental to geomorphology, and are also of applied interest as they affect buildings and structures made of natural stone. This supplementary volume contains a collection of 13 substantive papers originally presented at a workshop in Oxford convened by the British Geomorphological Research Group Fixed Term Working Group on Rock Weathering. The aim of the volume is to review a selection of new and established techniques for studying rock weathering and associated environmental factors (such as micro-climate and microbial colonisation). The first 8 papers discuss various aspects of field studies of weathering, including micro-catchment experiments, laser scanners, photogrammetry and mapping. The following 4 papers discuss aspects of laboratory experimentation and analysis of weathered material, including sampling strategies, measuring permeability and the use of microscopy. A final paper investigates some of the issues involved in weathering models.

Book Description :

In the beginning of 2007, indole arynes and their cycloaddition chemistry were discovered by Buszek laboratories. Since then, indole arynes and their cycloaddition chemistry have demonstrated their value in the construction of biologically active natural products, such as trikentrins and herbindoles. In addition to the tremendous value of indole aryne cycloaddition chemistry in natural products total synthesis, this chemistry has successfully contributed to library development and drug discovery fields. Taking advantage of the relative electronegativity of fluorine atoms, we proposed four polyfluoroindole scaffolds that could potentially generate the all three indole arynes, namely, 4,5 , 5,6-, and 6,7-indole arynes, from a single platform through a combination of dehydrohalogenation and metal halogen exchange chemistry. In these efforts, a practical and efficient synthetic scheme was constructed via the Fischer indole reaction in order to design the four trifluoroindoles from the corresponding trifluoroanilines - a single platform to generate the three indole arynes. This efficient Fischer indole synthetic scheme was used after earlier attempts with a previous and longer synthetic route to produce 4,6,7-trifluoro-1H-indole from 2,4,5-trifluoroaniline was unsuccessful. In spite of the fact that we were not able to obtain the desired compound through this previous synthesis, unexpected results were produced (i.e., diazo-oxides compounds). The four trifluoroindole systems, namely, 4,5,6-trifluoro-3-phenyl-1H-indole, 4,5,7- trifluoro-3-phenyl-1H-indole, 4,6,7-trifluoro-3-phenyl-1H-indole, and 5,6,7- trifluoro-3-phenyl 1H-indole, have now been synthesized via the Fischer indole reaction from the commercially available triflouroanilines in two-step synthesis. Calculated acidities of the four trifluoroindole systems were performed in the gas phase, which indicated the possibility of generation indole arynes from these scaffolds. By comparing proton chemical shifts of trifluoroindole and tribromoindole sets to indole itself, proton chemical shifts of trifluoroindole scaffolds shifted upfield whereas proton chemical shifts of tribromoindole shifted further downfield. Interestingly, this can indicate that in trifluoroindole systems, fluorine atoms shield the protons whereas in tribromoindole systems, bromine atoms deshield the protons. Two systems namely, 4,5,6-trifluoro-1-methyl-3-phenyl-1H-indole and 5,6-difluoro-1-R-3 phenyl-1H-indole were proposed as a potential “universal” indole aryne generating platform.

Book Description :

Conversion of biomass into chemicals and biofuels is an active research and development area as trends move to replace traditional fossil fuels with renewable resources. By integrating processing methods with microwave and ultrasound irradiation into biorefineries, the time-scale of many operations can be greatly reduced while the efficiency of the reactions can be remarkably increased so that process intensification can be achieved. “Production of Biofuels and Chemicals with Microwave” and “Production of Biofuels and Chemicals with Ultrasound” are two independent volumes in the Biofuels and Biorefineries series that take different, but complementary approaches for the pretreatment and chemical transformation of biomass into chemicals and biofuels. The volume “Microwave” provides current research advances and prospects in theoretical and practical aspects of microwave irradiation including properties, effects and temperature monitoring, design of chemical reactors, synergistic effects on combining microwave, ultrasound, hydrodynamic cavitation and high-shear mixing into processes, chemical and catalytic conversion of lignin into chemicals, pyrolysis and gasification, syngas production from wastes, platform chemicals, algal biodiesel, cellulose-based nanocomposites, lignocellulosic biomass pretreatment, green chemistry metrics and energy consumption and techno-economic analysis for a catalytic pyrolysis facility that processes pellets into aromatics. Each of the 12 chapters has been peer-reviewed and edited to improve both the quality of the text and the scope and coverage of the topics. Both volumes “Microwave” and “Ultrasound” are references designed for students, researchers, academicians and industrialists in the fields of chemistry and chemical engineering and include introductory chapters to highlight present concepts of the fundamental technologies and their application.
