Structural Characterization of Lignin Isolated from Coconut (Cocos nucifera) Coir Fibers

The structure of the isolated milled “wood” lignin from coconut coir has been characterized using different analytical methods, including Py-GC/MS, 2D NMR, DFRC, and thioacidolysis. The analyses demonstrated that it is a p-hydroxyphenyl-guaiacyl-syringyl (H-G-S) lignin, with a predominance of G unit...
