/ ..A'I'TOENEY "ran STATES OTTO LIEBKNECHT, OF FRANKFORT-ON-THE-MAIN, GERMANY, ASSIGNOB, 'IO THE ROESSLER & HASSLACHER CHEMICAL COMPANY, OF NEW YORK, N. Y., A CORPORA- TION OF NEW YORK.
REENFORCED YLATIiIUM ANODE FOR PRODUCTION OF PERSALTS.
Application filed August 27, 1921. Serial No. 496,050.
To all whom it may concern:
Be it known that I, OTTO LIEBKNEOHT, a citizen of the Republic of Germany, and a resident of Frankfort-on-the-Main, Germany, have invented a new and useful Reenforced Platinum Anode for Production of Persalts, of which the following is a specification. p
In the electrolysis of solutions containing alkali borates and carbonates, under the proper conditions perborate is formed and may separate out as a solid.
n this process platinum is chosen for the anode and the object of this invention is to make use of very thin sheets, foils or gauze of platinum in order to reduce the cost of the anode When such very thin anodes are used it is found that they are not rigid enough or strong enough to support themselves in the desired position relative to the cathode.
In one of our experiments we endeavored to reinforce the platinum with aluminum but the platinum-aluminum couple was loosened by electrolytic action at the point of contact of the two metals.
After many experiments we found to our surprise that zinc frames could be used for supporting the platinum and that no deleterious efiect resulted from the zinc platinum couple.
As an illustration of a method of utilizing my discovery Imay clamp a piece of platimum foil or gauze between frames of metallic zinc which are in turn connected to a conductor. These frames may be fastened by any suitable means-such as clamps, bolts, or screws.
As an example of my invention 1 refer to the accompanying diagram in which A is the main supporting member of zinc. B is a secondary supporting member or frame also of zinc. It is held in position by the curved lower edge of A and by the nine clamps CC. Da platinum gauze, is held between A and B and serves as the effective anode, electric connection from the bus bar E being made through the supporting frame A.
The advantages of this invention are that the anodes thus made are practically permanent and that no soluble materials are formed from the anode to decompose the per-salts formed by electrolysis.
What I claim is: v
1. A platinum anode reinforced with metallic zinc.-
2. Platinum anode for the production of solutions of per-salts characterized by the use of metallic zinc frames for reinforcing the platinum.
In testimony whereofl have signed my name to this specification in the presence 0B two subscribing witnesses.
