Patented in the German Empire on July 29, 1908,

The present invention relates to a method with the aid of which it is possible to obtain liquefied chlorine directly to fluids to be chlorinated or oxidized in better, faster and let it act more completely than is possible with the current methods is.

Many of the previous processes in which the chlorine is in a gaseous state

ίο Liquids, for example based on alkali, alkaline earth and in particular lime liquor to act for the purpose of obtaining hypochlorites, show the drawback that you can use of liquid chlorine, e.g. B. from chlorine bombs, the chlorine container for the purpose of more uniform and had to warm up faster gassing. Such a removal of the chlorine from the containers in the gaseous state is cumbersome for large-scale operations and takes too much time.

The immediate use of liquid chlorine to chlorinate liquids, etc. have faced great difficulties until today, since the chlorine in the liquid Difficult to bring the state out of the containers and into the reaction chamber evenly is, also easily accumulates in individual places and has an oxidizing effect on the hypochlorite already formed.

Even with good cooling and good stirring of the liquids was with the until now known attempts the occurrence of side reactions, for example the formation of chlorate as a result of over-oxidation cannot be avoided. For example, milk of lime shows this

A phenomenon which occurs easily even when treated with gaseous chlorine when treated with liquid chlorine.

According to the present invention, these inconveniences are now eliminated in that the liquid chlorine directly through spray nozzles, which the liquids to be treated do not touch, spread over the more or less vigorously moving liquids.

Here it is generally recommended to use liquid chlorine, in contrast to the previous one Frequently practiced working method to keep quite cool and the pressure, depending on the Type of process necessary and also of the cooling and reaction temperature, etc. of the apparatus and the process is dependent on generating the chlorine itself. Of the Pressure and the expansion cooling of the liquid chlorine then cause the gasification the fine particles of chlorine liquid is made more difficult, at least as long as they are not with have come into contact with the liquids to be treated. The procedure will Executed in a room that does not allow chlorine to escape and is pressurized can be. A few templates for liquids are expediently connected to this space and the venting device to this to reduce and equalize the pressure.

The rapidity of the atomization must be quite significant, from which it follows in turn that the liquids move according to their concentration and according to the course the reaction must be cooled.

Claims (3)

Also the atomization chamber, which has already cooled down considerably as a result of the expansion of the chlorine is to be kept quite cool or at least to be protected from the ingress of heat. It is advisable.. this part of the apparatus with stoneware slabs, which is usually made of iron, Line cement, lead, or other material. In general, the evaporation or dusting space is located above the well-moving liquid, but without the sprinkling nozzles touching the liquid. the Diffuser nozzles can also be arranged in a cylinder or a tower-like container be the appropriate with plates, sieves or similar devices for distributing the Liquids is equipped so that the chlorine against the steadily trickling down to be oxidized or blown liquids to be chlorinated. Any equipment that enables to bring the liquid chlorine into rain or dust form. In the accompanying drawing, for example, there are two for carrying out the method suitable devices shown, namely shows Fig. Ι an apparatus with horizontally lying, 2 shows such a cylinder-like or tower-like atomization and reaction container. A line b leads from several chlorine bombs α from the bottoms of the chlorine bombs into the evaporation, atomization and reaction container d, namely are located ■ at the mouths of the discharge pipes . Nozzles c made of chlorine-resistant material. Within the space d (Fig. 1) an agitator e of any shape is attached, which receives its movement from a pulley f. To maintain the correct reaction temperature, a cooling or heating device g provided in the lower part of the room and provided with an inlet and outlet is used. The upper part of room d is clad with lead, cement or stone slabs h and the like. A vent line i leads from these parts to a template k which is provided with a vent valve I or the like. The fresh and the finished chlorinated liquid are fed in through the pipe p. In the apparatus of FIG. 2, for the most part, the same devices are attached. In addition, an inlet pipe m for the liquid to be treated leads into the apparatus from above, while a discharge pipe η is attached to the bottom. The device g is provided here outside the apparatus; it can of course also be within. Pump 0 is used to achieve a fluid circulation. The process is not only suitable for the rapid production of large quantities of hypochlorite liquors by allowing the chlorine to act on alkali and alkaline earth solutions, in particular on milk of lime, the known ones Method easily occurring clogging of the chlorine supply devices is avoided, but also as a chlorination and oxidation process, for example acts, metal ores, metal or metal brine, z. B. gold ores, silver, iron salts, Manganese compounds, etc., organic bodies, e.g. toluene, acetic acid, alcohol, Camphor derivatives, etc., to be oxidized or chlorinated by chlorine. This process is also important when mixing liquid chlorine with other liquid Wants to bring gases together, z. B. with sulphurous acid for the production of sulphuryl chloride, in the production of acetic anhydride ο. Like. The higher the respective Reaction temperature is, the more carefully the process must be handled and, for example can be adapted to the nature of the reaction in question by using adjustable sprinkling nozzles. The special advantages of the process are the use of the evaporation cooling of the Chlorine, the speed of execution, the good yields, e.g. B. in hypochlorite representation, which are obtained without significant control of the process, the good distribution of the chlorine, the protection of the Chlorine introduction lines, as well as the already mentioned avoidance of the blockage of the To emphasize chlorine pipes by lime etc. Also, as with other procedures, there is no risk of resignation the liquids takes place when the chlorine line is empty. Furthermore, the substitution effect of the chlorine supply lines easily and without major operational disruptions. Since the procedure works directly with allows controllable amounts of liquid chlorine, so also the quantitatively accurate and even introduction of a certain amount of chlorine is greatly facilitated. Finally, the sprinkler nozzles with their large, possibly adjustable resistance are ideally suited, even for small pressure differences between the chlorine bomb and the atomization chamber ensure that the chlorine is supplied precisely to effect. P α τ ε ν τ claims: i .. Process for allowing chlorine to act on to be chlorinated or oxidized Liquids or suspensions different bodies, characterized in that the chlorine is directly in the liquid states due to the sprinkler nozzles or the like that do not touch the liquids the well moving liquids as fine rain is dusted to the chlorine for the purpose of avoiding side reactions and taking advantage of its evaporation cooling to bring into contact with the liquids in the finest division and to make a previous gasification unnecessary. 2. Execution of the method according to claim i, characterized in that the liquefied chlorine while maintaining the pressure generated by its evaporation is finely distributed on the well-moving liquids by sprinkling nozzles. 3. Embodiment of the method according to claim 1 and 2, characterized in that that the liquids in a cylinder or tower-like container, the appropriately equipped with plates, sieves, balls or other devices serving to distribute the liquids is, steadily trickling down, while the liquefied chlorine through nozzles, which are appropriate are arranged laterally, is introduced into the container in a finely divided manner. 1 sheet of drawings.
