Investigation on the effect of acetylation and reduction treatments on the chromophore groups of isolated lignin from unbleached hardwoods chemimecanical pulp using FT-IR spectroscopy
Volume 29, SPRING 1 , May 2014, , Pages 79-93
Abstract
This study lignin from unbleached hardwoods chemimechanical pulp was extracted and the chromophor functional groups of the lignin were studied. Acetylation and reduction treatments were perfomed and samples were analyzed by FT-IR spectroscopy. A mild acidic dioxin extraction method was employed to isolate ...

Volume 27, Issue 3 , September 2012, , Pages 556-568
Abstract
In this study, the chemical changes of functional groups (C=O) and double bond (C=C), induced in the structures of poplar kraft lignin and bagasse soda lignin were investigated. The reducing effect of sodium borohydride and sodium hydrosulfite, followed by the UV irradiation on these two compounds were ...
