| titleOfInvention | A kind of method that transition metal oxide catalyzes and oxidizes biomass to prepare monophenolic compound to co-produce cellulose |
| abstract | The invention discloses a method for preparing monophenolic compound and co-producing cellulose by catalytic oxidation of biomass by transition metal oxide. The method includes the following steps: (1) putting the pretreated dry-base biomass, transition metal oxide and alkali metal hydroxide aqueous solution into a closed reaction vessel, pouring oxygen into the reaction vessel, and stirring the reaction The mixture is reacted, and a suspension is obtained after cooling; (2) the suspension is centrifuged to obtain a supernatant and a solid residue, the supernatant is acidified with an acid solution to pH=2～3, and an organic solvent is added to extract the monophenolic compound, An organic solution is obtained, a weak base salt is added to the organic solution to remove water, and finally the organic solution is subjected to vacuum distillation to obtain a monophenol compound; the catalyst in the recovered solid residue is recycled for use. In the invention, lignocellulose is used as raw material, oxygen is used as oxidant, and transition metal oxide is used as catalyst, and monophenolic chemicals are prepared and cellulose is produced under mild conditions, so as to realize efficient utilization of lignocellulose. |
