Abstract:
PCT No. PCT/EP96/03596 Sec. 371 Date Feb. 6, 1998 Sec. 102(e) Date Feb. 6, 1998 PCT Filed Aug. 14, 1996 PCT Pub. No. WO97/07262 PCT Pub. Date Feb. 27, 1997The invention concerns the combined production of sodium peroxide disulphate and soda lye from sodium sulphate. According to the invention, electrolysis is carried out in at least one two-chamber electrolysis cell with cathode and anode chambers separated by a cation-exchanger membrane. The electrolysis temperature is set at between 30 and 70 DEG C., a sodium sulphate solution which is at least 75% saturated at this temperature is introduced into the anode chamber, the sodium ion concentrations are maintained in the range of between 4.5 and 6.0 mol/l and soda lye is extracted from the cathode chamber.
