  3. 2. Symmetry of Halonium Complexes in Solution

    Författare :Anna-Carin Carlsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bis pyridine -based halonium complexes; ethylenehalonium ions; structure symmetry; isotopic perturbation of equilibrium; solution NMR spectroscopy; isotope effects; N-X -N halogen bond; C-X -C interaction;

    Sammanfattning : In this thesis the symmetry of two interaction types involving electropositive halogens have been studied in solution; the N-X+-N halogen bond (X = Br or I), and the C-X+-C interaction of previously characterised, cyclic, 1,2-bridged halonium ions (X = Cl or Br), respectively. The three N-X+-N model structures included are bispyridine, 1,2-bis(pyridine-2-ylethynyl)benzene and 1,2-bis((4-methylpyridin-2-yl)ethynyl)benzene halonium triflate complexes. LÄS MER

  5. 4. Metal-Chelate Complexes in Alkaline Solution : On Recovery Techniques and Cellulose-based Hybrid Material Synthesis

    Författare :Alireza Eivazihollagh; Håkan Edlund; Magnus Norgren; Joakim Bäckström; Christian Ekberg; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : For decades, aminopolycarboxylate chelating agents have been extensively used in various industrial applications. The ability of chelating agents to form stable metal-chelate complexes is the main reason for using them to manage metal ions within water-based industrial processes. LÄS MER

  7. 5. Unsaturated Fatty Acids in Alkane Solution : Adsorption and Tribological Properties

    Författare :Sarah M. Lundgren; Per M. Claesson; Hugh Spikes; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Sammanfattning : Fatty acids and blends of fatty acids are used as friction modifiers and anti-wear additives in diesel fuels. A large part of some fatty acid blends are unsaturated fatty acids. Even though fatty acids have been thoroughly investigated, the adsorption and tribological behaviour of unsaturated fatty acids are no fully understood. LÄS MER
