REMOVAL OF CAUSTIC IN HEMICELLULOSE CAUSTIC

Pulping chemicals and hemicellulose are recovered from a starting solution essentially free of lignin but containing a mixture of hemicellulose and caustic by electrolysing this solution in the anolyte compartment of an electrolytic cell. By electrolysis, the concentration of caustic in the anolyte...

description	Pulping chemicals and hemicellulose are recovered from a starting solution essentially free of lignin but containing a mixture of hemicellulose and caustic by electrolysing this solution in the anolyte compartment of an electrolytic cell. By electrolysis, the concentration of caustic in the anolyte is decreased and the concentration of caustic in a catholyte of said cell is increased so as to allow recovery of about 60 to about 80 percent of the caustic contained in the hemicellulose caustic starting solution.
