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.

Ví dụ thực tế
The white paper in your books and notebooks was bleached using chlorine dioxide derived from electrolytically produced sodium chlorate.
Tầm quan trọng công nghiệp
About 3.6 million tonnes of sodium chlorate are produced annually, primarily for pulp bleaching, herbicides, and water treatment.
