Three-chamber electrolysis cell and process for the electrolysis of salts in it |
| abstract |
PURPOSE:To obtain 30 - 50% caustic alkali with highccurrent efficiency by using an electolysis bath whose cathode, anode and middle rooms are respectively separated by the specified cation exchange membrane. The caustic alkali content in the middle room is controlled to keep the value between 10 and 28%. |
