Effects of Lignite Fly Ash on the Degradative Pathways of Aqueous Amine Solvents
… the catalysis of the side reactions that affect alkanolamine solvents used in post-combustion carbon capture has been focused on dissolved metals present alongside them. These metals enter the process by way of suspended fly ash present in flue gas from coal-fired power stations. Once present in …

Mathematische Modellierung des MDEA-Absorptionsprozesses
… for many kinds of industrial purposes. Aqueous alkanolamine solutions are well suited for the selective absorption of sour gases like hydrogen sulfide and carbon dioxide. Alkanolamines are mainly used to clean fuel gas or synthesis gas. The most important field for the application of …

Reaction Kinetics and Dissociation constants of Tertiary Alkanolamines for Carbon Capture
… rate of the reactants. The different tertiary alkanolamine solvents studied in this research work have no kinetics data published in the literature, and the solvents were selected the solvents for research studies because of their unique characteristics and properties. The experimental …

Studies on the Degradation of Desiccants in Temperature Swing Adsorption Processes and the Adsorptive Separation of Sulfur Compounds from Industrial Fluids
… H2S and CO2 from industrial fluids is aqueous alkanolamine absorption. This process is often expensive as the regeneration is energy intensive. Thus, alternative technologies are sought after, such as adsorbents. One of the most promising adsorbents is activated carbon for removing CO2, H2S, …

Asymmetrische Synthese von Gamma-Hydroxy-Alpha-Aminosäuren, 1,3-Aminoalkoholen und 2-Amino-3-Phosphonopropionsäure
In this thesis we optimised a procedure to synthesize 1,3-amino alcohols and applied it to a wide range of substituted substrates. Starting from aldehyde SAMP-hydrazones we obtained beta-hydroxy SAMP-hydrazones in a titanium-mediated aza-analogous aldol reaction. After protection, 1,2-addition and …

1,3-Aminoalkohole als Bausteine in der asymmetrischen Synthese von Azetidinen, Azetidincarbonsäuren und Piperidin-3-olen
Four-membered cyclic amines – the azetidines – are an original class of compounds with limited occurrence in nature. Nevertheless enantiopure azetidines and in particular derivatives of the azetidine-2-carboxylic acid are used in medicine, crop protection and asymmetric catalysis. Despite these …

Synthese und Charakterisierung alternierender Polyesteramide auf Basis von Aminoalkoholen und cyclischen Anhydriden
The present thesis deals with the synthesis and the properties of alternating poly(ester amide)s based on a,w-amino alcohols and cyclic anhydrides. The synthesis of the poly(ester amide)s is performed by polycondensation of linear AB-monomers (a-carboxyl-w-hydroxy amides), in some cases …

Enantioselective synthesis of cyclic beta-amino alcohols via tandem hydroalumination-cyclization-reduction of ethoxycarbonyl vinyl sulfoximines and application to the synthesis of potential aggrecanase inhibitors
The beta-amino alcohol moiety is a common structural component in a wide variety of natural occurring compounds, synthetic pharmacologically important molecules, ligands and chiral auxiliaries for asymmetric synthesis. Due to the fact that the stereochemistry of the beta-amino alcohol moiety is …
