Lear peroxide4 is formed if between lead electrodes a 1 5 per cent, solution of sodium sulphate (99 5 parts) and sodium chlorate (0 5 part) be electrolysed with a current density of 5 amp. per dm.3 Air should be blown through this solution, and it should be acidified with sulphuric add. 

The sodium ions migrated into the cathode chamber where they formed sodium hydroxide, 52.6% of the sodium chlorate was converted to chloric acid at an operating temperature of 54 °C and a current density of 1.2kA/m. ... 

A process was devised some years ago by M. Moest for producing alcohol from fatty acids, and by subsequent oxidation the corresponding aldehydes or ketones. Por example, an organic acid in the presence of an inorganic add gives, as chief product, an alcohol containing one carbon atom less than the organic acid. In the presence of sodium chlorate, Moest obtained a yield of 34 per cent, methyl alcohol from sodium acetate, with a current density of 5-20 amps, per dm. , whilst with a current density of... 

Fig. 5.10 An industrial plant for the production of sodium chlorate (the Erco process). Production is typically up to 42000 tons per year of sodium chlorate. The process operates at a current density of 0.21-0.28 Acm and a temperature of 80-90° C. The electrolyte, which has pH 6.4-7, contains 1.5-5 gdm Na2Cr207.2H2O. Typical raw-material consumption per tonne of product are NaCl, 550 kg HCl, 15 kg NaOH, 10 kg Na2Cr207.2H2O, 2.5 kg. (Courtesy Albright and Wilson Americas.)...

If the soln. of sodium chloride be made alkaline by.the addition of alkali hydroxide the maximum concentration of the hypochlorite becomes less as the alkalinity of the soln. is increased and the chief products of the electrolysis are chlorate and free oxygen. The relative yields of hypochlorite and chlo- I rate during the electrolysis of soln. of 200 grms. of sodium chloride, and various amounts of the hydroxide per litre of soln., are indicated in Fig. 6, with an anode current density of O OI amp per sq. cm. It is assumed that the reaction representing the formation of chlorate in neutral, and in slightly and in strongly alkaline soln,... 

Perchlorates are made commercially by the electrolytic oxidation of chlorates. Sodium perchlorate is made first as a rule, and other perchlorates are prepared from it by double decomposition. The conditions for a good yield of perchlorate are concentrated neutral chlorate solution, temperature below 50°, current density 0.1 amp/cm or more, and anode of platinum. Platinum is better than graphite, probably because of its higher oxygen overvoltage. 

A third method to produce these so-called structured particles is to first form a particle with higher cross-link density and then lower the cross-link density in the center of the particle. Cross-linked polymers made in the presence of oxidizing agents such as sodium or potassium chlorate have shown improvements in absorbency under load and swelling capacity after a high temperature heating step (27) wherein a portion of the polymer chains in the particle center are cleaved through the action of the oxidizers.
