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： Described herein are devices and methods for the efficient and economic generation of lignin monomers from biomass. The provided devices and methods utilize reductive catalytic fractionation with an organic solvent to extract high-quality lignin from biomass and cleave specific lignin bonds to generate valuable lignin monomers with a relatively narrow product slate. Advantageously, the devices and methods described herein utilize solvent recycling, multiple solvolysis chambers with multiple biomass beds and/or physical agitation (e.g., use of a screw extruder) to reduce the amount of solvent required and increase economic efficiency and monomer yield.

摘要： What is disclosed herein is a method for depolymerizing polyolefins, comprising
a. preparing a catalyst comprising cobalt, nickel or both;
b. combining the catalyst with a sample comprising polyolefins in a reaction vessel in the presence of H2 gas to produce a mixture, wherein the polyolefin comprises a carbon chain having the structure (CH2CHR)n wherein R is an alkyl group and n is an integer greater than 20;
c. reacting the mixture under conditions effective to depolymerize the polyolefins to produce decomposition products, wherein the decomposition products comprise the structure (CH2CHR)m wherein m is an integer much less than n.
