  2. 1. Organic Synthesis in Nonionic Microemulsions

    Author : Maria Häger; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic reaction; phase behaviour; microemulsion; reaction kinetics;

    Abstract : The aim of this work has been to explore the use of microemulsions as reaction media for organic synthesis. Another important aim has been to improve the understanding of the reaction kinetics and the mechanism of the reaction in this type of surfactant system. READ MORE

  4. 2. Nonionic Microemulsions: Dependence on Oil Chain Length of the Surfactant Curvature Elastic Properties

    Author : Joakim Balogh; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Light Scattering; NMR relaxation NMR self-diffusion; SANS contrast variation and contrast matched studies; saddle play modulus; made by C12E5; Nonionic microemulsion; balanced microemulsion; Fysikalisk kemi;

    Abstract : The aim with this thesis has been to increase the knowledge about nonionic microemulsions and how they behave with increasing temperature. I have studied Nonionic Microemulsions made from C12E5, water and oil, with predominally hexadecane as oil, but also with octane, decane, dodecane and tetradecane as oil. READ MORE

  5. 3. Polymer effects on microemulsions and lamellar phases

    Author : Håkan Bagger-Jörgensen; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Poisson-Boltzmann equation; hard sphere; osmometry; small angle scattering; phase behaviour; hydrophobically modified polyelectrolyte; hydrophobically modified polymer; nonionic surfactant; microemulsion; lamellar phase; undulation force; Physical chemistry; Fysikalisk kemi;

    Abstract : The main part of this thesis deals with the effects of adsorbing and non-adsorbing polymers when mixed with microemulsion droplets and bilayers in a lamellar phase. The phase behaviour, microstructure and interactions in a nonionic surfactant/ water/ oil-system, comprising penta ethylene oxide dodecyl ether (C12E5) and decane, was investigated. READ MORE

  6. 4. Organic reactions in self-organized surfactant systems

    Author : Fredrik Currie; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic synthesis; kinetics; micelle; regioselectivity; microemulsion;

    Abstract : The aim of this work has been to investigate how microemulsions and micellar systems can be used as reaction media to overcome reactant incompatibility, enhance reaction rates and especially to control product composition, i.e., introducing regioselectivity, in organic synthesis.
