The invention discloses a lignin degradation method, which takes water as a solvent, and lignin is reacted for 10-60 hours at 100-120 ℃ under the protection of inert gas and the action of a double rhodium catalyst or a terpyridyl rhodium trichloride catalyst and alkali, so that the lignin degradation can be completed. Compared with the prior art, the method does not need additional hydrogen sources, takes water as a solvent, has mild reaction conditions, simple operation, environmental protection, reduced environmental pollution, high reaction yield and low industrial production cost. |
