    University dissertation from Umeå : Umeå universitet

    Author : Hans Andersson; Umeå universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Grignard reagents; pyridine N-oxide; pyrazine N-oxide; dienal-oxime; pyridine; ortho- metalation; piperidine; piperazine; asymmetric; NATURAL SCIENCES Chemistry Organic chemistry Organic synthesis; NATURVETENSKAP Kemi Organisk kemi Organisk syntes; organisk kemi; Organic Chemistry;

    Abstract : This thesis describes the development of new synthetic methodologies for preparation of bioactive interesting compounds, e.g. substituted pyridines, piperidines or piparazines. Thesecompounds are synthesized from commercially available, cheap and easily prepared reagents, videlicet the reaction between Grignard reagents and heterocyclic N-oxides. READ MORE

  4. 4. Energy Efficient Processes for the Production of Gaseous Biofuels - Reforming and Gas Upgrading

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Helena Svensson; Lunds universitet.; Lund University.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofuels; Reverse-flow reforming; Gas upgrading; Amine absorption;

    Abstract : Popular Abstract in Swedish Arbetet som presenteras i denna avhandling handlar om att utveckla nya processer för att producera gasformiga biobränslen som är mer energieffektiva än de som används idag. Genom att göra processerna mer energieffektiva kan kostnaden för att producera biobränslen minskas. READ MORE

  5. 5. Amphiphilic Molecules in Aqueous Solution

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Gerd Persson; Umeå universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; liquid crystal; phase diagrams; counterions; alkylpyridinium octanesulfonates; 1-monooleoyl-rac-glycerol; n-octyl-β-D-glucoside; cubic phases; Fysikalisk kemi; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : The aim of this thesis was to investigate amphiphilic molecules in aqueous solution. The work was divided into two parts. In the first part the effects of different counterions on phase behavior was investigated, while the second part concerns the 1-monooleoyl-rac-glycerol (MO)/n-octyl-β-D-glucoside (OG)/2H2O-system.
