Abstract

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
