Technical Feasibility to produce Modified Phenols from Lignocellulosic Materials

M.I. Lopretti Correa
The possible aplications of polymeric materials from renewable resourses depends on some modifications in the lignins structure. Two different samples of lignins were used; kraft lignin from E. grandis and solid lignocellulosic materials. The objective of this work is to obtain modified phenols and little poliphenols to use in copoliesters. We use two processes: enzymatic modifications of kraft lignins and solid fermentation to modificate lignocellulosic matherials. The enzymatic extracts of P. chrysosporium and G. trabeum...
