Lignin may serve as a renewable feedstock for the production of chems. and fuels if mild, scalable processes for its depolymerization can be devised. The use of small organic thiols represents a bioinspired strategy to cleave the β-O-4 bond, the most common linkage in lignin. In the present study, synthetic β-O-4 linked polymers were treated with organic thiols, yielding up to 90% cleaved monomer products. Lignin extracted from poplar was also treated with organic thiols resulting in mol. weight reductions as high as 65% (Mn) in oxidized lignin. Thiol-based cleavage of other lignin linkages was also explored in small-mol. model systems to uncover addnl. potential pathways by which thiols might depolymerize lignin. The success of thiol-mediated cleavage on model dimers, polymers, and biomass-derived lignin illustrates the potential utility of small redox-active mols. to penetrate complex polymer matrixes for depolymerization and subsequent valorization of lignin into fuels and chems. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Synthetic Route of C13H12O2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Synthetic Route of C13H12O2
