Abstract:
      Lignosulfonate exhibits excellent water solubility， high electronegativity and surface activity， can be widely used in many industrial fields， which is one of the lignin-based chemicals that have been realized industrial application. The production process， separation， and purification of lignosulfonate were summarized in this paper， as well as its application in dye dispersants. Current problems in the research of lignosulfonates were presented， and the research directions and prospects for industrial applications were outlined to provide a reference for the high value utilization of lignosulfonate products.
