Specification of Letters Patent.
Patented an. 1?; 1932.1.
Application filed February 8, 1910. tierial No. 542,164.
' To all whom it may concern the anode itself.
Be it known that I, GUSTAV Tnronnnn,
doctor of philosophy, chemist, a subject of the Emperor of Austria-Hungary, residing at 54 Gugelstrasse, Nuremberg, Kingdom. of Bavaria German Empire, have invented new and useful Improvements in Processes for Production of Compounds of Persulfuric Acid, of which the following is a specification. I
My invention relates to the process ofproduction of persulfuric acid by the electroly sis of sulfuric acid;
Hitherto the: roduction of persulfuric acid by electrolysis of sulfuric acid was can ried out in such a manner that the eleo trolyzed sulfuric acid was cooled down to temperatures below 10 centigrade, because at higher temperatures the formation of persulfuric acid is out small and only low concentrated solutions of persulfuric acid may, be obtained. As a temperature below 10 can only be maintained by means of cooling machines, large and costly cooling installations were required. Furthermore it, was necessary to add to the electrolyte hydro chloric acid and similar substances in order ,7
to increase the yield because pure sulfuric acid produces but a smali proportion of persulfuric acid. I have discovered that these inconveniences may be avoided h cooling the anode is ept at a temperature of about 1: the electroiyte- I may without harm reach a temperature of more than 20, the yield of persulfuric acid 1 being very small at this temperature it the anode is not cooled. The cooling can be easily elfcctecl by making the anode hollow and leading water of l2-15 through it. Special cooling machines are therefore un-' necessary Another great advantage is that the flddll lfln of hydrochloric acid and the like can he omitted, the cooled anode giving very good outputs of persulfuric acid even with" pure sulfuric acid.
The accompanying drawing shows a vertical section of an apparatus suitable for carrying out the process in accordance with this invention.
is the receptacle containing the liquid 5 to he electi'olyzed, c is the cathode, d the anode, h a porous clay diaphragm. The anode (Z is hollow. In the hollow space a Water is introduced by a tube and allowed to run out through the pipe 9. The cooling may also he etlected with other cooling means than water, for instance, salt solutions or air.
The process can be carried out as follows: Into the receptacle a is introduced sulfuric. acid o having a specific gravity of 1.35. The anode Z is refer-ably of platinum and the catholic c 0 lead. The current intensity is preferably 0.5 amperesper square centimeter anode.- The electrolysis is best carried out as rapidly as possible so as to avoid the formation of theCaro-s' acid which has a depolarizing action. This is effected-by making the volume of the electrolyzed liquid as small as possible, for iristanced-IO cubic centimeters electrolyte for 1 ampere. I
I claim: I
The process of production'oi persulfuric' 7 acid consisting in subjecting solutions of sud:
uric acid to eiectrhiysis cooling the anode and maintaining the sol utions of sulfuric.
acid during the electrolysis to ahigher tom perature than the anode which is cooled.
In testimony whereof I affix mysignature in presence of two Witnesses.v
