摘要： Described herein is a chemical process for the conversion of lignocellulosic biomass into muconic acid which is useful for the generation of plastics and polymers. The described methods utilize catalytic chemical reactions and biological processes to facilitate the conversion, while increasing yields and reducing energy requirements.

摘要： Described herein are systems and methods for the generation of bio-based plasticizers from lignin from 4-hydroxybenzoic acid (H), vanillic acid (G) and syringic acid (S) obtained via oxidative depolymerization of lignin substrates. Chemical and electrochemical methods are described for catalytic reductive coupling of sulfonate derivatives of H, G and S to generate all possible homo- and cross-coupling products. Advantageously, the provided systems and methods allow for the generation of renewable plasticizers that exhibit performance advantages relative to established petroleum-based phthalate ester plasticizers.

摘要： Disclosed herein are methods and compositions of matter showing that catalytic autoxidation can be used to generate aromatic monomers from C—C linked dimers and oligomers derived from lignin. This is demonstrated by acetylating phenol-rich RCF oil and then conducting aerobic oxidation of the oligomeric fraction of poplar RCF oil with a Co/Mn/Br catalyst mixture in acetic acid. This reaction yields a collection of oxygenated aromatic monomers that represent a 17% increase in monomer yield compared to the RCF process alone.
