Abstract

845,511. Electrolytic production of metal hydroxides. PERMUTIT CO. Ltd. Jan. 3, 1957 [Jan. 3, 1956], No. 193/56. Class 41. Metal hydroxides are prepared electrolytically in a cell divided into two compartments by a cation exchange membrane from an anolyte consisting of an aqueous solution of a salt of the metal of which the hydroxide is required, said salt forming an acid at the anode and said anolyte being in contact with a carbonate or oxide of the metal which is soluble in the acid formed to reform the metal salt, while the catholyte is an aqueous solution of the hydroxide or of a hydroxide readily separable therefrom. Preferably the anolyte is the sulphate of the chosen metal providing that this is soluble. If a chloride is used the replenishing material should be the oxide of the metal to avoid loss of chloride as chlorine which would result when venting the carbon dioxide evolved from the carbonate. The oxide or carbonate used may be added intermittently or may be dispersed to form a suspension in the anolyte in a separate vessel and circulated through the anode compartment. Reference is made to the production of barium, magnesium, and cupric hydroxides, while in the example described lithium hydroxide is produced from a lithium sulphate anolyte and a lithium hydroxide catholyte using a steel cathode and a lead anode.
