Biocatalytic conversion of cellulose towards itaconic acid
… production of platform chemicals such as itaconic acid. The biocatalytic conversion of cellulose is a very promising approach due to its high selectivity, mild conditions, and low exergy loss. However, such biocatalytic processes are still seldom applied at the industrial scale since the …

Synthesis of Functionalized Poly(dimethylsiloxane)s and the Preparation of Magnetite Nanoparticle Complexes and Dispersions
… nanoparticles stabilized with carboxylic acid-functionalized PDMS were prepared. PDMS-magnetite complexes were characterized using transmission electron microscopy, elemental analysis, and vibrating sample magnetometry. PDMS-magnetite complexes containing up to 67 wt% magnetite with …

Catalytic conversion of biomass-derived molecules into mono- and dicarboxylic acids and esters
… of fuels and chemicals. Mono- and dicarboxylic acids and esters are key intermediates to chemical products, especially for biodegradable polymers. This thesis has addressed the challenges in chemocatalytic synthesis of mono- and dicarboxylic acids and esters, including gluconic acid, succinic …

Hydrierung im invertierten Zweiphasensystem scCO 2/H 2 O
… was tested in case of the hydrogenation of itaconic acid as model substrate. Several CO2-philic rhodium-complexes were used. The best results were achieved using the fluorinated phosphine ligand 3-H2F6TPP and [Rh(cod)2]BF4. With a rodium:ligand:substrate ratio of 1:5:200, a conversion of 95% …

Selektive Hydrierung biogener organischer Disäuren mit Rutheniumphosphinkatalysatoren
In the scope of this work the hydrogenation of diacids was investigated in depth on the example of itaconic acid. Rutheniumcatalysts with phoshineligands were stable and active hydrogenation catalysts. Mono- and bydentate ligands catalyse the conversion towards the 2- and …

Synthetic polymers from building block chemicals produced by biorefineries - PLA-based polyesters and galactaric acid-based polyanhydrides
… forest industry and agriculture. Meso-galactaric acid can be produced biotechnologically from D-galacturonic acid, a major component of pectin-rich industrial side-streams from e.g. sugar beet processing and apple and orange juice production. 2,3,4,5-Tetra-O-acetylated galactaric acid was …

Investigating sustainable solutions for roadside gully pot management
… addition, including glucose, Tween 80 and itaconic acid, was assessed within these model gully pots. A composting trial was also executed under mesophilic and thermophilic conditions assessing the effect of a substrate addition (starch) on the waste. In order to assess the processes within …

Development of Catalyst on Polymer Support for Organic Compounds Destruction
… PAN and co-polymers (usually methylmethacrylate, itaconic acid, vinylsulphonate) have been produced since 1949 (Gheller B, 2002). Thus, in this work PAN fibre was chosen as a polymer support for a heterogeneous catalyst, and the work itself is actually a continuation of the research on PAN …
