APPARATUS FOR MANUFACTURING MERCURY BICHLORID.

Patented Dee. 3i), 1913.`

Original application led August 27, 1912, Serial No. 717,246. Divided and this application filed March 19, 1913. Serial No. 755,377.

T0 all 'whom t may concern Be it known that we, FELIX KAUELER, a subject of the Emperor of Austria-Hungary, and resident of Brckl, Carinthia, Austria-Hungary, and AUGUST KLAGES, a subject of the German Emperor, King of Prussia, and resident of Salbke, in the Province of Saxony, Kingdom of Prussia, German Empire, have invented new and useful Improvements in Apparatus for Manufacturing Mercury Bichlorid, of which the' following is a full, clear, and exact specification.

The invention relates to apparatus for preparin mercury bichlorid by the direct action o chlorin gas or mercury; and the present application `is a division of a prior vapplication filed by us on the 27th -day of August, 19.12, Serial No. 717,246, in which the' invention is shown and described but not specifically claimed. It has for its object to provide apparatu suitable for continuously burnin mercury in a current of chlorin gas and wich apparatus may be closed and of small size, whereby the same may be readily surveyed and escape of the mercury bichlorid vapors prevented. Danger to the workmen ,is thereby obviated, the bichlorid being obtained as a finished commercial product, requiringr no crystallization, sublimation or drying of the poisonous substance.

The invention has for its object, furthermore, to obtain mercury bichlorid in an extremely nely divided state and thereby avoid the troublesome pulverization of the solid mass, the product thus obtained, moreover, being chemically pure, of brilliant white color and much more voluminous than that heretofore obtained.

In the accompanying drawings, the apparatus employed for the production of mercury bichlorid is represented in side elevation, partly in section.

a designates the retort preferably consistin of quartz glass and provided with a ch orin admission tube b ending above the level of the mercury@ contained in the retort, and a mercury admission tube d terminating below the level of said mercury.

Both .tubes b and d, are also preferably made of quartz. As shown in the drawing, the mercur admission tube d can be disposed within the chlorin admission tube t), the mercury flowing through the tube d being thus preliminarily heated `by the chlorin at the open end of the tube Z1, before sai mercury enters the mats of mercury c. Both tubes may be provided with suitable valves e and f' for regulating the admission of the chlorin and mercury, respectively.

rlhe retort is heated by suitable means. In the drawing a gas burner g is shown, which may be of any' desired construction. Other heating devices, for instance electric heating appliances, may be used. l

The mercury lbichlorid formed in the retort may be discharged through the outlet tube h into a large tower z', which may be ot any suitable-material not attacked by the mercury bichlorid v apors. have found it preferable to luse glazed7 acidproof bricks. Into this tower air is admitted by means of a tube 7c provided with flame burning .a suitable regulating valve l, the air being preferably mixedV with a small percentage of chlorin, not exceeding say 10%. Thetube c preferably terminates near the end of the outlet tube L. Thus the air becomes mixed bichlorid it is preferable, though not absolutely necessary, to provide a second tower n connected to the tower i by means of a tube 0..V rlhe tower n may also be provided with a man-hole and cover p. In this tower,

-. which may be made of clay, the last traces of mercury bichlorid are deposited. The

apparatus is, furthermore, provided with a tube g connected with a suitable suction device (not shown). Generally it will be sufcient to connect the tube g with a chimney; or instead of suction devices, the gases may be introduced under pressure.

The process is rendered continuous by passing the current of chlorin gas continually through the apparatus, and in constantly admitting fresh quantities of mercury tothe chlorin flame, burning above the boiling mercury level, by allowing the mercury, which has preferably been preliminarily heated by the said chlorin flame, to enter below the level of the boiling mercury. The reaction is assisted by gentle heating In practice wev andthe Whole reaction vessel is iilled with la brilliant green flame. The bichlorid thus tals are much more voluminous than the `product obtained heretofore vby the usual processes, one liter of the mercury bichlorid thus obtained weighing only 1400 grams, whereas the usual powdered mercury bichlorid weighs 2800 grams per liter.

We do not limit ourselves to the l details of the apparatus shown, which may be varied in practice. without departing'from the scope of the invention.

We claim 1. In an apparatus for burning a liquid in a gas the combination of a retort, a as admission tube, a liquid admission tu e, terminating below the normal liquid level in the retort and located inside the gas admission tube, an outlet tube for the productof combustion, and means for-heatmg thegre-V tort.

2. In anapparatus ,for` manufacvzturing mercury bichlorid the' combination of," a quartz retort, a quartz admission tubefor chlorin and a quartz admission tube 'for mercury, the latter terminating below the normal mercury level in the retort and loheating the retort, and means for condenscated inside .the chlorin admission tube, an

outlet tube for the mercu bichlorid formed in the retort, and means or heating the retort.

3. In apparatus for l manufacturing mercury4 bichlorid the combination ofa retort, a chlorin admission tube,a mercury admission tube, an outlet tube for the mercury blchlorid vformed in the retort, means for ing the mercury bichlorid vapors,

4. In an apparatus for manufacturing mercury bichlorid the combination of a retort, a chlorinA admission tube, a mercury admission tube, an outlet` tube for the merfcury bichlorid formed in the retort, means for heating the retort, a tower into which the `outlet tube opens, and means for introducing a current of air into said tower to chill the vapors from said retort.l

5. In an apparatus for manufacturing mercury bichlorid the combination of a rei tort, a chlorin admission tube, a mercury admission tube, an outlet tube for the mercury bichlorid formed in the retort, means for heating the retort, a tower into which the outlet tube opens, and means for introducing air into said tower in a jet discharging across the retort discharge tube.

6. In an apparatus for manufacturing mercury bichlorid the combination of a retort, a chlorin admission tube, a mercury admission tube an outlet tube for the mercury bichlorid v`formed in the retort, means for heating the retort, and a tower into which the outlet tube opens, and an air admission tube opening into the tower and terminating near the end of the outlet tube Ito chill the vapors from said retort.

7. In an apparatus for manufacturing mercury bichlorid the combination of a quartz retort, a quartz admission tube for chlorin and a quartz admission tube for l mercury, the latter terminating belowy the normal mercury level and located inside the chlorin admission tube, an outlet `tube for themercury bichlorid formed in the retort, means for regulating the admission of chlorin and mercury, means for heating the retort, 'a condensing tower of glazed acidproof bricks, andan air admission tube opening into the tower and terminating near the end of the outlet tube to chill the vapors from said retort.

In testimony that we claim the foregoing as our invention, we have si ed our names in the presence of two subscribin witnesses.
