Xanthogenation of Lignocarbohydrates by Carbon Disulfide

  • Published:
Chemistry of Natural Compounds Aims and scope

Abstract

High-molecular-weight products containing 4.21-10.4% bound sulfur that are soluble (32-86%) in aqueous alkaline solutions are obtained from xanthogenation of lignocarbohydrates by carbon disulfide in the presence of NaOH in propan-2-ol. The degree of preliminary alkaline activation of the raw material in propan-2-ol has the principal effect on the composition and physicochemical properties of the xanthogenation products.
