Abstract
Methods for the production of syringol from biomass are provided. Reactive diluents derived from syringol and their use in 3D printing are also provided.
Claims30
A method for producing syringol from a biomass, comprising:
- introducing a composition comprising the biomass and a solvent into a reactor;
- feeding an oxygen source into the reactor;
- heating the composition at a temperature below 200° C. while continuously feeding the oxygen source into the reactor to depolymerize lignin in the biomass, thereby yielding a depolymerized lignin composition comprising syringol;
- and
- obtaining syringol from the depolymerized lignin composition.

A method for producing syringol from a biomass, comprising:
- introducing a composition comprising the biomass and a solvent into a reactor;
- feeding a first amount of an oxygen source into the reactor;
- heating the composition at a temperature below 200° C. until oxygen in the first amount of oxygen source is depleted to depolymerize lignin in the biomass, thereby yielding a depolymerized lignin composition comprising syringaldehyde and syringic acid;
- and
- converting syringaldehyde and syringic acid into syringol.
