Experimental studies have shown a strong positive effect of NaCl addition on the decomposition rate of chlorate in aqueous solutions. It is more reasonable in the chlor-alkali industry to first saturate the brine with sodium chloride and then eliminate chlorate by adding HCl to protect the electrolysis cell from chlorate ions.
The decomposition rate of chlorate (NaClO3) in aqueous solutions (brines) containing initially 6:1 mol/mol HCl:NaClO3 is studied at 90 degrees C at various NaCl contents experimentally. A strong positive effect of NaCl addition is shown on the decomposition rate of chlorate. It is found more reasonable in the chlor-alkali industry first to saturate the brine by sodium chloride and only then to eliminate from it the chlorate by adding HCl (before the solution is transferred into the electrolysis cell to be protected from the chlorate ions).
