Investigating the Effect of Structural Changes of Alkali Lignins Caused by Reduction and Methylation Reaction on the Optical Characteristics of Lignin-Containing Papers
In this study, changes in optical behavior of poplar Kraft lignin and bagasse Soda lignin, before and after reducing with sodium borohydride and sodium hydrosulfite (dithionite) and also after methylation using dimethyl sulfate, was monitored by measuring optical indices (brightness, k/s, whiteness...
