Title: The Treatment of Alkali Chromates for the Production of Bichromates and Alkali therefrom
Inventor: JOHNSON GEORGE WILLIAM
Filed: 1903-08-13
Granted: 1904-05-12
Abstract: 17,588. Johnson, G. W., [Chemische Fabrik Griesheim Elektron]. Aug. 13. Alkali bichromates and hydrates are produced simultaneously, by electrolysing alkali chromates. Potassium or other alkali chromate is introduced in both compartments of an electrolytic cell, having a suitable diaphragm and provided with electrodes of lead, platinum, or the like, the anode not being attacked by the solution, and the cathode not reducing the alkali chromate. A current is passed until all the chromate in the anode compartment is transformed into bichromate. The anode liquid can then be discharged into crystallizing-vessels. The mixture of alkali and chromate produced in the cathode compartment may be evaporated down until the chromate separates out. The cell is preferably heated to keep the voltage required low. A cell, consisting of material capable of acting as a diaphragm, may divide an iron trough into two compartments. The trough is connected to the negative pole of a source of electricity. The proportion of alkali contained in the cathode compartment at the end of the operation must not be too high. The liquid may be circulated through the cathode compartment to render the work independent of the duration of the action going on at the anode.
