  2. 2. Scots pine (Pinus sylvestris L.) sapwood modification by vinyl acetate-epoxidized plant oil copolymer

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Shengzhen Cai; Sveriges lantbruksuniversitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : A new bio-based formulation consisting of plant oil and vinyl acetate was developed for wood modification aiming at improving some of the material’s properties. In–situ epoxidation of linseed oil (LO) and soybean oil (SO) was carried out at different times with purpose of preparing epoxidized oils with various epoxy content. READ MORE

  3. 3. Possibilities to Utilize Species from the Mozambican Forest Biomass for the Production of Essential Oils : Study of Eucalyptus and Pinus Species and Application of Citronellal as Raw Material for Flavour Chemistry

    University dissertation from Stockholm : Kemi

    Author : Felisberto P. Pagula; KTH.; [2004]
    Keywords : Eucalyptus species; essential oil composition; citronellal; hydroxycitronellal;

    Abstract : This thesis deals partly with the isolation and chemicalanalysis of essential oils from selected Eucalyptus and Pinusspecies grown in Mozambique, and partly with the synthesis ofmore valuable compounds from citronellal isolated fromEucalyptus citriodora Hook oil.More than 60 constituents in the volatile oils wereidentified by gas chromatography and gas chromatography-massspectrometry by comparison with authentic substances andliterature data.

  4. 4. Cost-effective cultivation of lodgepole pine for biorefinery applications

    University dissertation from Stockholm : Kemi

    Author : Ingegerd Backlund; Sveriges lantbruksuniversitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The overall objective was to evaluate the scope for the cost-effective cultivation of lodgepole pine (Pinus contorta, PC) stands in a way that would enable early biomass harvesting to supply raw material for biorefineries. Commercial direct seeded PC stands were shown to produce 200 m3/ha of stemwood or 100 tons of d.w. READ MORE
