dc.description.abstractEn | Attempt to depolymerize industrial organosolv lignin (from sugarcane bagasse) and lignins extracted from sugarcane bagasse and Miscanthus fibers (isolated by a soda/anthraquinone process) in presence of an anthraquinone acid catalyst (AQCOOH) was described. With the aim to substitute formaldehyde by glutaraldehyde, a dialdehyde that can be obtained from natural sources, lignins were reacted with glutaraldehyde and studied as phenolic-type resins for thermosets. The reactions were predominantly analyzed be SEC and P-31 NMR spectrometry. The Organosolv lignin-glutaraldehyde resin was used to prepare a composite reinforced with sugarcane bagasse fibers. Control samples were also prepared; specifically, composites based on phenol-formaldehyde and organosolv lignin-formaldehyde matrices. The results of the impact and the flexural strength tests of these composites showed that the organosolv lignin and glutaraldehyde can successfully replace phenol and formaldehyde, respectively. | |
