Abstract
Carbon disulphide and aqueous potassium hydroxide solutions act on alkali lignin, forming very viscous mixtures from which colloidal, lignin-like materials containing sulphur and of high molecular weight may be isolated.The hypothesis is advanced that a lignin xanthate may be a step in a theoretical series of reactions culminating in the formation of the materials isolated.The presence and condition of the sulphur in the isolated product are discussed from the standpoint of this hypothesis.
