  4. 3. Sample Preparation of Organic Compounds in Environmental Analysis using Liquid Membrane Extraction

    Författare :Luke Chimuka; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reverse phase liquid chromatography; octanol-water partition coefficients; phenolic compounds; s-triazines; supported-liquid membrane extraction; environmental analysis; UV detection; Analytical chemistry; Analytisk kemi;

    Sammanfattning : This thesis demonstrates the potential of the liquid membrane extraction technique as an alternative method for the analysis of trace ionisable organic compounds in the environment. Liquid membrane based extraction methods for the analysis of s-triazine herbicides and phenolic compounds were developed. LÄS MER

  5. 4. Mapping Phenolics Metabolism and Metabolic Engineering of Saccharomyces cerevisiae for Increased Endogenous Catabolism of Phenolic Compounds

    Författare :Peter Adeboye; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; toxicity; Keywords: Phenolic compounds; Saccharomyces cerevisiae; conversion; inhibitor;

    Sammanfattning : AbstractSustainable, biotechnological utilization of non-food, plant biomass has been demonstrated to be a viable means of producing energy, fuels, materials and chemicals, representing a paradigm shift from fossil-derived sources. However, the presence of chemicals that inhibit fermentation by microorganisms such as Saccharomyces cerevisiae, commonly used for bioconversion, causes a bottleneck in such processes. LÄS MER

  7. 5. Lignin Model Compounds: Synthesis, Stereochemistry and Acidolysis

    Författare :Shiming Li; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boric acid complexes; Arylglycerol b-aryl ethers; stereochemistry; 3-Diaryl-2-propen-1-ols; 1; Phenylcoumarans; lignin model compounds; acidolysis; ion-exchange chromatography; 3-propanediols; 2-Diaryl-1; 2; X-ray crystallography;

    Sammanfattning : Lignin model compounds representative of structural elements in lignin of the b-1, b-5, b-O-4, cinnamaldehyde and cinnamyl alcohol types were synthesized. erythro-Forms of b-1 models of the 1,2-diaryl-1,3-propanediol type were prepared by BF3-catalyzed rearrangement of chalcone epoxides and subsequent reduction of the rearrangement products with NaBH4.
