PRODUCTION OF FEERIG SALTS.
ferrous salts of polybasic acids, for example ferrous sulfate and ferrous tluosilicate.
A further objectto provide a process for the purpose mentioned which can be practical with apparatus of the simplest possible character.
In the production of such salts by elec trolytic methods one of the chief difliculties encountered is polarization at the anode, with resulting loss of eiliciency and destruction of the carbon anodes through increased resistance to the electrolyzing current, and in a prior patent granted to me November 7, 1905, No. 503,543, I have de scribed a process in which the diilioulty referred to is practically overcome by pro ducing' large relative movement between the anode and the electrolyte, so to facilitate the continuous oxioation of the ferrous salt by the liberated anions. I have discovered, however, thatsatistactory results can be oblained without such relative motion it the solution is el'ectrolyzedat. a high tempera-. ture. For example, it a solution of ferrous sulfate and sulfuric acid is electrolyzed at a ten'iperature of from 50 to 100 Q, using a carbon anode, the electrolysis proceeds without appreciable polarization at the anode and without evolution of gases, and
a large percentage of the ferrous is-conrerlcd into ferric salt, with very lughcurrent OlllCltilCy. Just what is the lowest ten .perature perinissil'ile depends on circumstanceasueh as current density at the anode and the percentage of acid and of ferrous iron in the solution. At temperatures of 50? (l. and below l have not been able to oxidize iron successfully Witlmutkeeping: up a relalive motion between the anode and the solution:
As a specific instance of the practice of my method I may hire the following: A solution containing; grains iron as :terric Specification of Letters Patent.
Application filed January '7, 1909. Serial Patented Sept, Iii 31910.
Sulfate, 1.0 grams iron as 'i'crrous sulfate, 1.3"?) grams copper as copper sulfate, and about 4 grams free sulfuric'acid per 100 cc., can be electrolyzed at a temperature of 80 (1., with a graphite anode, at an anodecurrent density of 11 ainperes per square foot, without showing more than slight extra polarization beyond that necessary for the formation of ferric sulfate. The same solution at a temperature of 70 (1., with a current density of 8.5 aniperes per square foot, shows an extra polarization of half a volt or over, which still greater at lower temperatures. With a current density of 1&5 ainperes per square foot there is an extra polarization of over half a volt at 84 (3., showing the necessity of using a still higher temperature at the higher current density. By circulating the electrolyte, or moving the anode, as described in my prior patent before referred. to, a lower temperature may be used. in fact especially good results are obtained by employing considerable relativeniotion and some bea t, the relative motion necessary being less as he te1nperature rises,
What I claim is:
l. The process of oxidizing in solution ation sufficiently high, as described, to sub;
stantially prevent the evolution of oxygenvcontaining at the anode, as set forth.
The process of oxidizing in solution a ferrous salt of a polybasic acid to a ferric salt, which consists in eleetrolyzing the solution with an insoluble anode while maintaining the said solution at a temperature higher than 50 (L, as set forth 3. The process of oxidizing in solution a ferrous salt of a polybasic acid to aferric salt, which consists in electrolyzinp; the solution with an insoluble anode while main taining the said solution. at atemperature between 50 and 100 (1 approximately, as set forth. v
