  1. 1. Biotransformations of Turpentine Constituents Oxygenation and Esterification

    Detta är en avhandling från Stockholm : Kemi

    Författare :Marica Lindmark-Henriksson; KTH.; [2003]
    Nyckelord :Picea abies; Pinaceae; Essential oils composition; Terpene alcohol; Hemiacetal; Hemiacetal ester; TMP-turpentine; Monoterpene; alpha-pinene; beta-pinene; Limonene; Verbenol; Pinocarveol; Borneol; Myrtenol; Suspension cell culture; Biotransformation; ;

    Sammanfattning : This thesis describes methods to obtain value–addedcompounds from TMP-turpentine obtained from the spruce, Piceaabies. The methodology focuses on biotransformations using twoapproaches: an oxygenation approach (i.e. oxygenation ofterpene hydrocarbons by cell cultures) and an esterificationapproach (i. LÄS MER

  2. 2. Hepatic lipase and dolichol esterification

    Detta är en avhandling från Stockholm : Karolinska Institutet, false

    Författare :Pavel J. Sindelar; Karolinska Institutet.; Karolinska Institutet.; [1997]

    Sammanfattning : Doctoral Dissertation 1997 Clinical Research Center, Novum and Department of Neuroscience Karolinska Institutet Stockholm, Sweden Dolichol is one of the mevalonate pathway end products, present in all tissuesand cellular membranes. The lipid is a primary alcohol consisting of 16-23 isoprenoidresidues and occurs as a free alcohol, monophosphate or fatty acyl ester. LÄS MER

  3. 3. Cellulose processing in ionic liquid based solvents

    Detta är en avhandling från Stockholm : Karolinska Institutet, false

    Författare :Carina Olsson; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; esterification; cellulose; NMR spectroscopy; solution spinning; dissolution; ionic liquids; cellulose derivatives; rheology; crystallinity;

    Sammanfattning : As the most abundant polymer in nature, cellulose has an undisputed role among the raw materials to be used in a sustainable future. From its native form, in wood or straw, cellulose can be processed into products such as paper and board. LÄS MER

  4. 4. Aerobic Oxidative N-Heterocyclic Carbene Catalysis via Multistep Electron Transfer - Method Development and Applications

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Anton Axelsson; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene; asymmetric synthesis; esterification; glycerol; electron transfer mediator; green chemistry; telescoped reaction; Organocatalysis; aerobic oxidation; dihydropyranone;

    Sammanfattning : Oxidation reactions are ubiquitous in synthetic chemistry, but generally suffer from formation of large amounts of potentially toxic byproducts. Aerial oxygen represents an ideal oxidant since it is inexpensive, non-toxic and only forms water as a byproduct. LÄS MER
