Conclusions Under the action of a dc electric current having a voltage of 10–50 V on viscose under steady conditions, heating and electrolysis of the viscose take place; the temperature is increased nonuniformly throughout the volume of the cell: the preheating takes place more intensively in the anode compartment. The ripeness of the viscose and the degree of esterification of the cellulose xanthate are considerably reduced, and the gel-particle content decreases slightly; decomposition of the cellulose xanthate takes place via a dixanthogenide to the thioanhydride and low-molecular sulfur-containing products.
