SPECIFIOATIONforming part of Letters Patent No. 271,906, dated February 6, 188B.
Application filed October 5. 1882. (No model.) Patented in Belgium September 1, 1882. v
To all whom it may concern Be it known that I, ANDRE LEOPOLD Now, a subject of His Majesty the King of the Belgians, and residing atBrussels, Belgium, have 5 invented a new and useful process of and apparatus for the productionof chlorine gas and of metallic sodium by the decomposition of chlorideof sodium through the agency of dynamic'electricity, (for which I have obtained to a patent in Belgium, bearing date thelst of September, 1882,) of which the following-is a specification.
My invention relates to certain means and apparatus for decomposing chloride of sodium 1 5 by dynamic electricity into two constituent elements-via, sodium and chlorine- -the decomposition being eflected by means of a special form of -vat or trough, which I call the N 01f Apparatrrs, and into which is placed the solution of chloride of sodium to be acted upon. The various effects produced simultaneously by the Nolf apparatus are as follows: The sodium is reduced to a metallic state and prevented while in that state from decomposing 2 5 the water of the solutioninwhich it is placed. The chlorine is allowedto disengage itself in a gaseous state, so that it may beeasily collected. All polarization of the electrodes'in the bath which is subjected to decomposition c is prevented. The solution of chloride of sodium is always maintained at the same degree of concentration withoutthe necessity of stopping the decompositionfor a single moment. v
3 5 The following is a description of the apparatus, referencebeing had to thethree figures of the annexed drawings.
Figure l isa vertical transverse section of the apparatus. Fig. 2 is a horizontal section 4.0 on line as a; of Fig. 1, and Fig. 3 is a sectional detail view on the liney y of Fig. 1.
A is a trough, made of hard wood, its interior being coated with a varnish which will resist the action of the chlorine.
B is the bottom of trough, formed of sheetiron, perfectly flat. w r
G is a rim or flange of sheet-iron, which encircles the whole of the-vat or trough, forming a rim or ledge on its outside of about eight or 5013611 centimeters, ontowhich the cover of the apparatus is bolted. i a
D is'the cover, also formed of sheet-iron, slightly domed, and perfectly adjusted to the rim or flange.
E are boltsplaced at equal dis} noes around the whole circumference ofthe cover, and which, when once tightened up, should insure a hermetic closing. An india-rubber ring is placed between the cover and the rim or flange to secure this perfect closing.
G is a vertical iron shaft or axle passing through the center of the apparatus cover.
H is an axle or shaft, formed of hard wood, perfectly true, and fixed solidly to the iron axle, of which it forms the continuation.
I is a stuffing-box, in which the axle G revolves freely, while at the same time maintaining a hermetic closing.
J is a cast-'ron sleeve inclosing the lower end of the wooden axle H. The upper part, L L, of the sleeve is arranged in theform of a cross to support four wooden arms, hereinafter described. w B. is a bearing fixed to the bottom of the vat or trough.
MM are arms, formed of hard wood, strongly fixed by means of bolts N N to the cross of the iron sleeve.
0 O are pieces ofgas-retort carbon, thirty centimeters long, ten centimeters wide, and'three or four centimeters thick. Passing through the wooden arms M, they project a short dis tance above the upper part, and are fastened to the arms in such a manner as not to move in any way. These carbons form the positive electrode of the decomposing-bath.
c 11 represent a layer of mercuryone centimeter in thickness resting on and covering the bottom of theapparatus, and forms the negative electrode of the bath.
P is an iron tube of five millimeters interior diameter, bentlike a siphon, and provided with a cock, also made of iron, for emptying the mercury when required.
Q. is a mercury-pressure gage for indicating the pressure which may be formed inside the apparatus.
R is an irontube one centimeter in diameter, rigidly fixed to the cover, which it traverses, and passes down to within two millimeters of the bottom of the apparatus. This tube is for the purpose of charging the apparatus with mercury when necessary, and its upper part is widened out in the form of a funnel.
S is a leaden tube three centimeters interior diameter, fixed on the cover, and serving for the escape of the chlorine gas.
T is the gearing for communicating a slow and regular rotary motion to the vertical axle.
U is a partition of thin wood, fixed rigidly to the inside of the wooden trough, and serving to producea continuous stirring of the solutionwhen the agitator is-in motion. This partition is called a depolarizer, because the stirring it produces prevents any adherence of bubbles of gas to the surface of the electrodes.
V is a glass tube of small diameter passing through the apparatus cover and resting on the layer of mercury on the bottom. In this tube is a copper wire which puts the layer of mercury in the apparatus into communication with the negative pole of a dynamo-electric machine.
X is a copper ring fixed to the axle Gr, but at the same time completely insulated therefrom by an intermediate sleeve of india-rubber or gutta-percha.
Yis an iron piece'fixed at its base to the cover, but completely insulated there-from,-its upper part carrying a flat brush of silvered copper wire, which impinges against the circumference of the ring X. This brush is put into communication with the positive pole of the dynamo-electricmachine by means of a copper conducting-wire.
a is a small vertical groove on the iron axle, commencing at the place where the ring X is fixed and terminating at the lower end of the iron axle.
b is a platinum wire fitting into the groove a, from which it is insulated, and serving to conduct the electric current from the ring X to the upper part of 'all the carbons O O, to which it is strongly fastened by means of pinchers or fasteners of any kind. When the contacts are perfectly established the platinum wire, the pinchers or fasteners and all the other points of contact are carefully covered or coated with a mastic varnish not affected by the chlorine. It is also essentially necessary to insure the perfect insulation of" the platinum wire from the cross L L of the pivot-sleeve.
e e are tubes of vulcanized india-rubber, eight centimeters interior diameter, fixed to and passing through the cover. The bottoms of these tubes are made very thick, and they are pierced with a number of small holes up to about ten centimeters from their bottom. The upper part of these tubes is slightly widened or funnel-shaped. They are kept constantly filled with chloride of sodium, and are called alimentary tubes, their object being to always maintain the solution under decomposition at the same degree of concentration.
Having thus completely established the apparatus, the cover is well bolted on, and a concentrated solution of chloride of sodium in a cold state is allowed to flow into the apparatus by means of an india-rubber tube arranged in any suitable manner. When it has reached a height of forty-five centimeters the inletcock is closed and a dynamo-electric machine (which should be placed as close as possible to the apparatus) is put in motion. A slow and regular motion is imparted to the axle G, when the decomposition of the chloride of sodium instantly commences. The liberated sodium is attracted to the negative electrodet' e., the mercury-with whichit forms an amalgam, which preserves it from any decomposing action on the water, while the chlorine in a gaseous state, finding no body at the positive electrode with which it can combine, disengages itself abundantly, flowing through the escape-tube S in the cover. The sodium or the am al gam of sodium is collected by simply openin g the cock on the small emptying-tube P at the bottom of the apparatus. This amalgam is very fluid when care is taken not to allow it to become charged with too much sodium, and it flows of itself. toward this tube by slightly tilting the whole apparatus. When the mercury charged with sodium has been extracted and the apparatus placed upright the inlettube R is opened, allowing a fresh charge of I pure mercury to flow to the bottom of the apparatus. The general arrangement of the apparatus is such that the two operations effected by one attendant are completed without the necessity of stopping the dynamo-electric machine. The sodium contained in the amalgam is then utilized as required.
By distilling a part only of the mercuryaconcentrated amalgam of sodium may be formed, the use of which is so important in the treatment of gold or silver ores by amalgamation.
By distilling the whole of the mercury, pure sodium is obtained for the treatment of certain metallic ores. Finally, caustic soda, chemically pure, may be manufactured and a large quantity of hydrogen obtained by simply placin g the sodium amalgam in warm water, which is rapidly decomposed.
As regards the gaseous chlorine, it is conducted by the escape-tube S to the place where it is required to be used-either to the limechambers for forming hypochlorite of lime, or into a solution of soda forforminghypochlorite of soda, or into a series of Woulff'appara-. tus to mix with water and form chlorated water to the maximum of chlorination, or directly into paper-pulp or tissue bleaching troughs, or into special receivers containing auriferous arsenical pyrites previously well roasted and slightly moistened with water for the phrpose of effecting the complete chlorination of the gold contained in the pyrites. Finally, the chlorine gas may be utilized by: meansof special apparatus to rapidly chlorate the silver contained in a large number of oxidized metallic ores.
By the above-described apparatus and process l practically utilize for industrial purposes the strong aifinity of sodium when in a nascent state for mercury, and thereby insure the stability of the amalgamated sodium so long. as it remains hnder electric'influence. Further, I utilize the absolute want-of affinity of chlorine in a nascent state for gas-retort carbon, forming thepositive electrode,thereb y in the presence of mercury audin a close vessel, as. described. i v
