To aZZ whom it may concern.-
Be-it know-n that 1, JAMES D. DAR1JING,. 0f the city of Philadelphia, in the State of Penn sylvania, have invented acertain new and useful Process for'UtilizingNiter-Cake or. other Acid Sulfates and Obtaining Valuable By-Products Therefrom, 0t which the following is a specification. p r In the commercial manufacture of' nitric acid, and alsoof sulphuric acid, when nitrate of soda is employed to furnishthe' nitrogen compounds required, the resulting "by-product has approximately the composition of bisulphate of soda, although there is usually an excess of sulphuric acid pres-- ent, even beyond the amount which would be due tothe formula NaHSOp This byproduct, termed niter-cake, is of trifling commercial value, and various methods have been attempted to utilize it, but so far as I- am aware, all of such methods arerelatively costly and the commercial results therefrom have been neithersati'sfactory nor profitable.
My process is principally addressed to the economical and efficient treatment of nitercake for the derivation of two by-product's, viz: neutral sulphate of. soda (Na SO and chlorine gas. the utilization of other acid sulphates, with corresponding results.
To this'end my process consists in electrically decomposing a solution which contains a base similar to that of the acid sulphate, and causing such base to travel (by electrical action) toward, and combine with, the acid sulphate, juntil the desired neutralization thereof has been efiected. The other deriva;
tive of the electrolyticdecomposition is con ducted awayunderp'roper control, and'recovered as a distinct by-product. For convenience of nomenclature,1 term the solution which is to be thus decomposed, (in order to furnish an additional quantity of base to the acid sulphate,) the base-supplying electrolyte, and I term the transfer of the base from the region of its decomposition -to the region of rel-combination, the electrolytic travel thereof.
In the accompanying drawing 1 have representedin vertical section atypical apparatus adapted to the conduct of my process, but I It may, however, be applied to do not limit myself to e em ioymentbrthisshown in said-drawing.
'A, represents a tankof wood or slate, di-
vided into three compartments by means of the transverse partitions, B, B. These partitions should be in whole or in part porous, to an extent sufficient to allow of electrolytic travel, unaccompanied by any excessive increase in electrical resistance; In the central compartment (which is the decomposing cell)-isplaced a carbon electrode, D, which constitutes the positive pole, and in each of the {othercom-,- partments is placed an electrode, E, which may be of sheet lead, constituting-negative is provided .with a close fitting cover, F,having an outlet, G, and a ,feed orifice, H. The,
"poles. The centralor positive compartment central compartment is filled with the basesupplying electrolyte, whichis a saturated solution offsodium chloride,fland the two adjacent compartments are filled "to the same level with aso'lution of miter-cake. The physi; cal intermingling of the two solutions, as such, is practically prevented by the partitions, B, but on passing a suitable current of electricity from the positive to the negative pole of the apparatus, the sodium chloride solution in the central compartment is decomposed and the sodium, is caused to travel;
through the porous partition to the region of the niter-cake solution, where it combines with the surplus sulphuric acid and forms eutral sulphate of soda; while the liberate chlo-,
.rine passes 0% through the outlet pipb,G, to
any convenient receptacle, where it .inay be absorbed by lime, or condensed into liquid form directly, or utilized in any desired man-- 'ner. As the process proceeds, chloride of sodium may be supplied through the feed orifice, H, in the cover, F, and the process may be thus continued until the entire charge ofacid sulphatecontained in the negative compartment has been neutralized and the desired product obtained. The solution of neutral sulphate is .then drawn ofiand'afte'r filtering to free it from precipitated iron and otherimpurit ieais allowed to crystallize." The too mother liquor, with the addition of a proper to'a certain extent of the sulphuric acid takes place and oxygen is liberated at the positive pole, which action tends vto disintegrate the carbon electrode. There is also the further liability to a physical intermingling of the two solutions, so that at the close of the process the neutral sulphate would contain more or less of the sodium chloride diffused lhrough it. These objections are, however, not vital, and hence I do not limit my claim to the employment ofthe specified type of apparatus.
I do not limit myself to the employment of this process in connection with niter-cake, as it may be applied to the treatment of other acid sulphates for the production of neutral salts. It isof course necessary that the basesupplying electrolyte should insuch case be of a character to correspond to the salt to be neutralized. 1 q I claim- 1. The hereinbefore described process for the treatment of acid sulphates, which con-' sists in electrically decomposing an electrolyte containing a similar base to that of the sulphate, andtransferring said base to the sulphate by electrolytic travel, substantially as described. 7
2. The hereinbefore described process for the treatment of acid sulphates,which consists in electrically decomposing an electro-' lyte containing a similar base to that of the sulphate, transferring said base-to the sulphate by electrolytic travel, and recovering the gaseous product of said decomposition of the basesupplying electrolyte, substantially as described.
