Electrolytic Production of Chlorate

NaCl + 3H2O → NaClO3 + 3H2

Tổng quan

Electrolysis of hot NaCl solution without a membrane allows chlorine produced at the anode to react with hydroxide from the cathode, forming hypochlorite that disproportionates to chlorate at 70–80°C. Sodium chlorate (NaClO₃) is the precursor to chlorine dioxide (ClO₂), the dominant bleaching agent in modern paper mills.
