The bulky methoxy functionality, which is rich in oak and pine, sterically hindered the ether bonds, decreasing the yields of phenolic monomers and improving the beta-beta coupling to repolymerize lignin fragments. Both depolymerization and repolymerization are improved at a higher reaction temperature. The structures and the reaction behavior of organosolv lignin are observed using NMR, GPC, N-2-physisorption, SEM and DLS analysis methods.
