  1. 1. Biotransformations of Turpentine Constituents Oxygenation and Esterification

    University dissertation from Stockholm : Kemi

    Author : Marica Lindmark-Henriksson; KTH.; [2003]
    Keywords : 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; ;

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE

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

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

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

    Abstract : 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. READ MORE
