Title
(EN) METHOD FOR SELECTIVE CLEAVAGE OF COMPOUND COMPRISING AROMATIC RING AND C-O-C LINKAGE
(FR) PROCÉDÉ DE CLIVAGE SÉLECTIF D'UN COMPOSÉ COMPRENANT UN CYCLE AROMATIQUE ET UNE LIAISON C-O-C
Abstract
(EN) A method for the selective cleavage of a compound comprising an aromatic ring and a C-O-C linkage in the presence of a heterogeneous catalyst. By using this method, it is possible to increase the selectivity and/or yield (preferably both) of aromatic compounds.
(FR) L'invention concerne un procédé de clivage sélectif d'un composé comprenant un cycle aromatique et une liaison C-O-C en présence d'un catalyseur hétérogène. Grâce à ce procédé, il est possible d'augmenter la sélectivité et/ou le rendement (de préférence les deux) de composés aromatiques.
