| 摘要 |
Alkali metal chlorides are electrolyzed to the corresponding carbonates by employing a cell cathode which is continugous to a permselective cation exchange membrane which divides the anolyte compartment from the catholyte compartment, while introducing carbon dioxide into the catholyte, either in the cell or while it is recirculating outside the cell. Suitable membranes are those containing hydropholic ion exchange groups such as sulphonic groups, carboxylic groups or sulphonamide groups. |
