Abstract
1501276 Electrodialytic conversion of salts to weak acids IONICS Inc 17 Sept 1975 [29 Oct 1974] 38206/75 Heading C7B A cell for converting a water-soluble salt of a weak acid to the corresponding acid comprises a container divided into 4 individual chambers 5, 6a, 6b, 7, the cell having at the terminal ends a cathode chamber 7 and anode chamber 5 containing respective electrodes 10 and 9, first and second adjacent intermediate chambers 6a and 6b between 5 and 7, cation-permeable membranes 2a, 2b and 2c separating the chambers as shown, and means for separately introducing and removing fluids from each of said chambers from a hold-up tank 30, 31, 32, 33 associated with each of said chambers, and means for passing D.C. between the anode and cathode. In an example, the anode is Pb-Sb having an oxide coating, the cathode is stainless steel, the anolyte is H 2 SO 4 and the catholyte is NaOH. The salt is Na citrate; this is fed to both chambers 6a and 6b; migration of H
