    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; solvent-free process.; Candida antarctica lipase B esterification; chemo-enzymatic epoxidation; Unsaturated fatty acids; epoxides;

    Abstract : Epoxy fatty acids are useful molecules and find a number of applications e.g. as PVC plasticisers and stabilisers, additives in polyurethane production, reactive diluents in paints, corrosion protection agents, etc. READ MORE

  4. 2. Chemo-enzymatic epoxidation: Activity and stability of Candida antarctica lipase B

    Author : Ulrika Törnvall; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Growing concerns about climate change and depleting fossil feedstocks are driving a shift within the chemical industry from energy-intensive processes to more environmentally sound and sustainable processing using renewable feedstocks. One such process is the utilization of lipases for the chemo-enzymatic epoxidation of vegetable oils and fatty acids. READ MORE

  5. 3. Lipase catalysed synthesis of speciality chemicals: technical, economical & environmental aspects

    Author : Pär Tufvesson; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green Chemistry; surfactant; biocatalysis; enzymatic; epoxide;

    Abstract : Most people agree that the total ecological impact of society has become more than this planet can endure. This is because we consume our resources (such as oil and water) faster than they can regenerate and because we release more substances into the environment than can be assimilated (e.g. CO2).
