The invention discloses a method for directional catalytic production of vanillyl ketone and acetic acid from biomass. The method directly converts various forms of lignin reaction substrates into vanillyl ethyl ketone and acetic acid by constructing an alcohol ionic liquid conversion system. The reaction temperature is low, the reaction time is short, and the target product selectivity is high; While the aromatic structure is converted into vanillyl ketone, its side chain is also converted into the bulk chemical acetic acid, which is in line with the concept of atom economy. Compared with the current method for producing vanillyl ketone in industry, the method has better sustainability and greater application potential. |
