  5. 3. Chemical Interactions between Fatty Acids and Wood Components during Oxidation Processes

    Author : Alireza Salehi M.; Mats K G Johansson; Gunnar Hemriksson; Heikki Tenhu; KTH; []
    Keywords : ;

    Abstract : Fatty acids auto-oxidation on wood is proposed to follow a complex free radical interaction mechanism. The aim of this study was to analyze the effect of wood constituents on oxidation of fatty acids and thereby the entire drying process, and to characterize the fatty acids-wood interaction by using analytical instruments such as RT-IR and NMR.
