ABSTRACT:
A novel process for the preparation of an alkali metal halate by electrolysis of an aqueous alkali metal halide solution comprising passing an alkali metal halide solution upwardly through a plurality of bipolar electrolysis units while passing an electrolysis current therethrough at a temperature of 90.degree. to 110.degree. C and at a current density to volume ratio of 15 to 30 A/liter to convert at least a portion of the alkali metal halide to alkali metal hypohalite, passing the resulting electrolyte while venting the hydrogen formed to a reaction zone whose volume is sufficient to provide a residence time to substantially complete the conversion of the alkali metal hypohalite to alkali metal halate and recovering the said halate from the electrolyte and an apparatus for performing the said process.
