PROCESS FOR PREPARING AQUEOUS SOLUTION OF SODIUM HYDROXIDE |
摘要 |
<p>Production of an aqueous solution of sodium hydroxide from electrodialysis of sodium carbonate in an electrodialysis cell with three compartments is claimed. A solution of sodium carbonate is introduced in one compartment of the cell delimited between two cationic membranes. An acid is added to one compartment delimited between one of the cationic membranes and a cationic side of a bipolar membrane. An aqueous solution of sodium hydroxide of a compartment adjacent to the anionic side of the bipolar membrane is then extracted.</p> |
