  1. 1. Isotopes as Mechanism Spies Nucleophilic Bimolecular Substitution and Monoamine Oxidase B Catalysed Amine Oxidation Probed with Heavy Atom Kinetic Isotope Effects

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Susanna MacMillar; Uppsala universitet.; [2006]
    Keywords : Organic chemistry; nucleophilic bimolecular substitution SN2; kinetic isotope effects; precision conductometry; monoamine oxidase B MAO B; reaction mechanism; carbon 11C 14C kinetic isotope effect; ion pairing triple-ion formation; para-substituted benzyl chlorides; tetrabytylammonium cyanide; Organisk kemi;

    Abstract : This thesis concerns the study of reaction mechanisms by means of kinetic isotope effects (KIEs). Studies of the nucleophilic bimolecular substitution (SN2) reaction had the dual purpose of improving our fundamental understanding of molecular reactivity and assessing the ability of kinetic isotope effects to serve as mechanistic tools.

  2. 2. Studies of the anomeric center : mechanism and synthesis

    University dissertation from Stockholm : Stockholm University

    Author : Karl-Jonas Johansson; Stockholms universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organisk kemi; Organic Chemistry;

    Abstract : This thesis is based on three publications and one appendix and is divided into two parts. The first part is a mechanistic study of the anomerization reaction of both aldo and keto glycosides and the second part is a synthetic study of a unusual type of glycosidic linker found in the lipopolysaccharide core Proteus Mirabilis 0270.

  5. 5. Micro-reaction Mechanism Study of the Biomass Thermal Conversion Process using Density Functional Theory

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Xiaolei Zhang; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass thermal conversion; cellulose pyrolysis; char steam gasification; adsorption; interaction; mechanism; quantum chemistry; density functional theory;

    Abstract : Biomass, or bio-energy, is one of the most important alternative energies because of environmental concerns and the future shortage of fossil fuels. Multi-scaled bioenergy studies have been performed in the division of Energy and Furnace Technology, which included studies of macroscopic systems such as systems and reactors, modeling of computational fluid dynamics (CFD), and atomic/molecular level studies.
