Structure elucidation of prot, alkali and dealkaline lignin(s) by NMR, FT-IR and Py-GC/MS: effect of solid acid and base catalysts

Mechanistic breaking of lignin(s) was studied to see their potential toward valuable compounds. The breaking of bonds in the H, G, and S-type sub-aromatic units was affected by the acidic and basic properties of the catalyst(s).
