Studying on the Soda and Dioxane Lignin of Bagasse using Derivatization Followed by Reductive Cleavage (DFRC)

In this study, the structure of Soda (soluble fraction in ethanol) and Dioxane lignins of bagasse were studied by using derivatization followed by reductive cleavage (DFRC) method and some techniques including gel permeation chromatography, gas chromatography-mass spectrometry and 13C-nuclear magnet...
