ELECTROCEHMICAL PROCESS AND REACTOR FOR PRODUCING SULFURIC ACID AND SODIUM HYDROXIDE

摘要

An electrochemical process for the production of sulphuric acid and sodium hydroxide by the electrolysis of an aqueous solution of sodium sulphate in which the concentration of the aqueous sodium sulphate solution which is electrolysed is greater than that of a saturated solution of sodium sulphate under neutral conditions and at the temperature employed. The process may be effected in a two-compartment electrolytic cell (1) comprising an anode compartment (2) and a cathode compartment (3) separated by a cation-exchange membrane (4).
