METHOD FOR PRODUCTION OF OXIDANT ON THE BASE OF POTASSIUM PEROXIDICARBONATE

摘要

FIELD: chemical technology. SUBSTANCE: method is carried out by electrolysis of concentrated carbonate electrolyte. Desired product which contains potassium peroxidicarbonate (its quantity being 70-80 weight %), potassium carbonate and potassium hydrocarbonate is crystallized by interaction of products of electrolysis with carbon dioxide. All the stages of said process are carried out 0-10 C. Mentioned above electrolysis takes place in 3.9-5.4 M solution of potassium carbonate at 0-10 C. Said crystallization is carried out at (-5)-(+10) C by bubbling of 0.1-2.0 M carbon dioxide, quantity of carbon dioxide being 0.1-2.0 M per 1 g.-equiv. of peroxide compounds. EFFECT: improves efficiency of the method.
