Development of Themethod of Abies Wood Ethanollignin sulfonation Using Sulfamic acid

The method of obtaining of water soluble sulfated lignin based on the treatment of ethanollignin of abies wood by sulfamic acid in 1,4-dioxane medium in the presence of basic catalyst urea was developed. The introduction of sulfate groups into the structure of lignin is confirmed by data of elementa...

Description
Summary:The method of obtaining of water soluble sulfated lignin based on the treatment of ethanollignin of abies wood by sulfamic acid in 1,4-dioxane medium in the presence of basic catalyst urea was developed. The introduction of sulfate groups into the structure of lignin is confirmed by data of elemental analysis and IR-spectroscopy. The developed method of sulfated lignin synthesis is more simple and safe, than the known methods.
