| Sodium ligninsulfonate is an organic substance with the chemical formula C20H24Na2O10S2, lignin is a natural polymer second only to cellulose and chitin in nature, and one of its most widely used applications is to be transformed into lignin sulfonates by sulfonation modification, including sodium ligninsulfonate. [Sodium ligninsulfonate can be used as an admixture for polymers and concrete, and has the advantages of low cost and environmental friendliness. | |||||||||
