Abstract:

Eight substrates with the general structure 11.0 were synthesized. The substrates differed with respect to the heteroatom tether (X = oxygen or nitrogen), nitrogen protecting group (PG = p-toluenesulfonamide, tert-butylcarbamate, methyl carbamate), and substitution on the ring (Y = H or Ph). Silver (I)-catalyzed cycloisomerizations of the enesulfonamide and enecarbamate substrates successfully gave eight diene products ll.la-h in poor to good yields (36-81%). Diene ll.Ia was also further subjected to the Diels Alder reaction, with acrolein and methacrolein to give tricyclic cycloadducts 11.21a

Abstract:

As the demand for motor vehicles has soared dramatically with the emergence of rapidly developing countries, the need for regulating vehicle emissions and pollutants is increasingly more important. With the newest regulations for diesel particulate emissions soon to be enforced, there is a great need to catalytically convert soot particles from the exhaust into relatively less polluting carbon dioxide. Here a supported silver catalyst is reported for the soot oxidation reaction. The silver catalyst is protected and supported using various capping agents and metal oxides, and modified using var

Abstract:

This thesis describes an experimental and modelling study of the kinetics of silver-catalysed formaldehyde production via methanol partial oxidation and dehydrogenation. In methanol oxidation, the reaction is controlled by the gas phase diffusion of reactants towards the catalyst surface. The methanol-to-oxygen ratio at the catalyst wall is 100-200 times higher than that in the feed, which means that the reaction operates with large excess of methanol and therefore is solely controlled by the availability of O2 at the surface. A constant stoichiometry = 2.25 is found. In methanol dehydrogena

Abstract:

Propylene is the second most important starting chemical in the petrochemical industry after ethylene. Unlike ethylene, propylene readily undergoes substitution reactions including polymerisation, oxidation, halogenation, hydrohalogenation, alkylation, hydration, oligomerization and hydroformylation, which lead to a wide variety of important downstream products. One of the principal uses of propylene is to produce key chemicals from selective oxidation. In 2016, the world annual production of propylene is about 94 million tonnes, and the global proportion used to produce selective oxidation pr

Abstract:

Selective oxidations are important for the functionalization of compounds in organic synthesis and chemical industry. Using O2 as a terminal e- acceptor would be ideal because it is cheap and environmentally friendly, but aerobic oxidations are often prone to unselective free radical autoxidation. Recently developed palladium catalysts use O2 as a selective multi-electron oxidant for various organic transformations. Although these methods are powerful and sophisticated, the lower cost of base metals makes them attractive as potential alternatives. The challenge is to develop methods for ef

Abstract:

This research focuses on the development of a biological treatment process to enhance silver recovery from a low grade, silver-bearing manganese ore. These manganese oxide ores have been classified as refractory and thereby characterized noncommercial for the recovery and production of silver by conventional methods. A species of Bacillus polymyxa, which was isolated from the Crystal Hill Mine in southern Colorado, facilitated the reductive dissolution of manganese dioxide. Insoluble Mn(IV) was reduced to soluble Mn(II), and silver ions contained within the manganese oxide lattice were release

Abstract:

Since recent years, pollution of surface and drinking waters by chemical pollutants fromanthropogenic activities, in particular micropollutants, has become an important environmentalissue in industrialized countries. Indeed the majority of these molecules are toxic toliving organisms, even present at very low concentrations (pg.L−1 to μg.L−1). Some of themare referred as endocrine disrupting compounds. The existing conventional wastewater treatmentsare most of the time not adapted for the removal of these compounds. Among them,advanced oxidative processes give the better removal efficiencies,

Abstract:

The catalytic oxidation of bisphenol A (BPA) by laccase (EC 1.10.3.2) has recently attracted considerable attention because laccase can rapidly transform potentially persistent and toxic pollutants such as bisphenol A in the presence of molecular oxygen. Direct treatment of wastewaters containing bisphenol A would require excessive amounts of laccase if the enzyme is lost with the effluent and, thus, treatment would be cost-prohibitive. Therefore, strategies are desired for retaining the enzyme in the treatment system. It was envisioned that this could be accomplished by extracting poll
