Sodium chlorate was produced in a monopolar cell having platinized titanium anodes and steel cathodes. A high current density was used in order to minimize cell costs. A 144‐amp cell was built and tested in a continuous experiment for 31 days. The energy requirements were 6300 kwhr d.c./ton NaClO3 . The replacement platinum which may not have been optimized was shown as 5.3 normalg/ton NaClO3 . The cell operated at 1 amp/in.2, and 110°C. The cell feed contained approximately 190g normalNaCl and 330g NaClO3 per liter. Cell effluent contained 11Og normalNaCl and 580g NaClO3 per liter. The average cell voltage was 3.7. The pH was 6.7. This process is the subject of U.S. Patent 3,043,757. A cell with variable electrode spacings and height was used to indicate that ⅛ in. spacing would be preferred with electrodes 3 ft high in the commercial cell design.
