| titleOfInvention | Method for one-step photocatalytic lignin depolymerization and amine synthesis into nitrogen-containing aromatic compound |
| abstract | A method for one-step photocatalytic lignin depolymerization and amine synthesis into a nitrogenous aromatic compound belongs to the technical field of lignin application. Dissolving lignin or a model compound thereof serving as a reaction substrate in a solvent, reacting for 6-24 hours at room temperature under the assistance of an auxiliary agent and a nitrogen source under the excitation of a light source and the catalysis of a photocatalyst, and carrying out selective cracking and amination on a C-C bond so as to synthesize a nitrogen-containing aromatic compound; the molar ratio of lignin or a model compound thereof, the photocatalyst, the auxiliary agent and the nitrogen source is 100: (1-20): (1-100): 100. the method has the advantages of simple reaction steps, mild reaction conditions, high bond breaking selectivity, high product selectivity, 100% atomic efficiency, environmental protection, realization of selective cracking and amination of C-C bonds through one-step reaction, continuous feeding, good degradation effect on natural lignin, capability of obtaining nitrogen heterocyclic compounds through further reaction of hydrazine products and the like. |
