ilnrrn STATES PATENT OFFICE.
CARL LUOKOVV, OF COLOGNE-DEUTZ GERMANYt PROCESS OF PRODUCING WHITE LEAD BY MEANS OF ELECTROLYSIS.
SPECIFICATION forming part of Letters Patent NO. 627,002, dated June 13, 1899.
i Application filed December 31, 1897. Serial NOD66 5,210. ,(No specimens.)
To all whom it may concern.-
Be it known that I, CARL LUOKOW, a subject of the King of Prussia, Emperor of Germany, residing atGologne-Deutz, Germany, have invented certain new and useful Improvements in Processes of Producing White Lead by Means of Electrolysis, of which the following is a specification.
Theinvention has been patented in England, No. 14,801, dated August 6, 1895.
The object of this invention is to produce white lead by means of electrolysis.
It consists, essentially, in the use of a salt of chloric acid with sodium, potassium, or ammonium in mixture with a salt of carbonic acid with sodium potassium or ammonium in aqueous in connection with the lead anode solution.
The mixture should be about eighty per cent. of one of the salts named above of chloric acid and about twenty per cent. of one of the salts named above of carbonic acid and the aqueous solution should contain from 0.3 to three per cent. of the mixture, the quantities of salt always calculated free from water. This solution serves as electrolyte. The electrodes are of lead. Under the influence of the electric current the lead of the anode is dissolved by the chloric acid of the one salt forming chlorate of lead which dissolves and is directly precipitated by the carbonic acid By the use of such two salts in about such proportions and such weak aqueous solutions the white lead formed does not adhere to the anodes, but falls oif and the anodes keep.
bright.
The process goes on continuously with the same electrolyte, as the chloric acid is not decomposed'by the electric currentandas the carbonic acid and water consumed in the process are always .added as they'are con sumed.
Example: A diluted solution one and onehalf per cent. strong of a mixture of eighty weight parts chlorate of sodium and twenty weight parts carbonate of sodium forms the electrolyte. sist of lead.
The electrolyte is faintly alkaline.
The tension of the current is two volts.
The current is fifty amperes.
The density of the current is 0.5 amperes per square decimeter of anode surface.
The electrolyte has to be kept faintly alka line during the electrolysis and water and carbonic acid have continuously to be added.
What I claim is The herein-described process of producing white lead by meansof electrolysis by using in connection with anodes of lead an aqueous solution as electrolyte containing from 0.3 to three per cent. of the sodium potassium or ammonium salts of chloric acid in mixture with the sodium, potassium or ammonium salts of carbonic acid, passing the current The anode and the cathode conthrough the electrolyte and continuously 7 adding carbon dioxid and water.
In witness whereof I have hereunto set my hand in presence of two witnesses.
CARL LUOKOW.
