Summary

Automatically generated

Here, we present a protocol to perform ethanol extraction of lignin from several biomass sources. The effect of the extraction conditions on the lignin yield and β-O-4 content are presented. Selective depolymerization is performed on the obtained lignins to obtain high aromatic monomer products.
