Texto completo da fonteDue to the depletion of fossil resources, the interest of lignin as a sustainable alternative to petroleum is growing. Thus, the main purpose of this thesis was to develop a process for oxidative cleavage of lignin by dioxygen that involves unconventional methodologies like sonochemistry and ball-milling. The catalysts used here were KEGGIN molybdovanadophosphates (PMoVx). First, the operating conditions (solvent, catalytic charge and vanadium content) were optimized to afford the cleavage of two models, 2-phenoxyacetophenone (K1HH) and 2-phenoxy-1-phenylethanol (A1HH), at atmospheric O2 pressure, into phenol, benzaldehyde and benzoic acid. For A1HH, harsher conditions were found to be necessary (O2 5 bar, 120°C). The catalysts were conventionally synthesized using a hydrothermal pathway, which consists in the H3PO4 attack of MoO3 and V2O5 in reflux water. A long heating period is often required to get moderate yields of PMoVx. Ball-milling synthesis was therefore considered. It consisted in preparing a mixed oxide by grinding MoO3 and V2O5. The latter's attack by H3PO4 was then shorter, took place at a lower temperature and resulted in higher yields of PMoVx. The activity of thus obtained PMoVx for model cleavage was similar to that of their hydrothermally synthesized counterparts. Preliminary tests on an Organosolv lignin from wheat straw under optimized conditions yielded low yields of cleavage products. Sonochemical assistance was therefore tested showing, in the case of A1HH, that a low frequency in conjunction with dioxygen bubbling was the best option
