Bekanntlich werden Nitroverbindungen, ζ. Β. Dinitro- und Polynitrophenolsalze, wie beispielsweise Dinitrokresolnatrium, Dinitrophenolnatrium usw., unter anderem auch als mycocide Substanzen benutzt. Die Verwendung bzw. das In-Handel-Bringen dieser Produkte, insbesondere für den überseeischen Transport, erscheint insofern nicht unbedenklich, als beim Eintrocknen dieser Pasten Körper hinterbleiben, welche außerordentlich stark explosiv wirken. So sind bekanntlich Dinitrophenolsalze, z. B. ι · 2 · 4-Dinitrophenolnatrium, ferner Dinitrokresolnatrium, sowie auch die Trinitroverbindungen sehr explosiv, so ' 15 daß ein Lagern und Transportieren der hochkonzentrierten Pasten dieser Salze in nicht feuersicheren Räumen gefährlich ist, da beim Ausbrechen eines Brandes die Pasten rasch eintrocknen und dann zur Explosion gelangen würden.It is well known that nitro compounds, ζ. Β. Dinitro and polynitrophenol salts such as Dinitrocresol sodium, dinitrophenol sodium, etc., also as mycocidal substances used. The use or the placing on the market of these products, especially for overseas transport, does not appear to be harmless in this respect, than when these pastes dry out, bodies are left behind, which are extraordinarily strong act explosively. So are known dinitrophenol salts, z. B. ι · 2 · 4-dinitrophenol sodium, furthermore, sodium dinitrocresol, as well as the trinitro compounds are very explosive, see above 15 that a storage and transport of the highly concentrated pastes of these salts in not fire-proof rooms is dangerous, because when a fire breaks out, the pastes quickly dry up and then explode.
Es wurde nun gefunden, daß man die Explosivität solcher Körper in äußerst einfacher und billiger Weise dadurch beheben kann, daß man diese Körper mit ligninsauren bzw. ligninsulfosauren Salzen, das ist Sumtzelluloseablauge, mischt. Man kann auf diesem' Wege, nämlich durch Eindampfen dieser Pasten, auch nicht explosive feste Produkte erzeugen. S° erhält man "beispielsweise eine versandfähige, selbst beim künstlichen völligen Eintrocknen nicht mehr explosive Paste, wenn man Dinitrophenolnatrium oder auch das kochsalzhaltige Dinitrophenolnatrium, wie man es durch Umsetzung von Dinitrochlorbenzol mit Natronlauge erhält, mit etwa der gleichen Menge oder der I1Z2 fachen Menge oder weniger etwa 8oprozentiger Sulfitzelluloseablauge ohne oder mit. Zusatz von Soda, Natronlauge usw. vermischt. Durch Eintrocknenlassen bei nicht zu hoher Temperatur, z. B. im Vakuum, werden feste Produkte erhalten, welche sogar beim brüsken Erhitzen nicht explodieren, sondern nur verglimmen. Soll die Explosibilität von Nitrokörpern nicht völlig aufgehoben, sondern nur herabgestimmt werden, so . setzt man wesentlich weniger an ligninsulfosaurem Salz hinzu.It has now been found that the explosiveness of such bodies can be remedied in an extremely simple and inexpensive manner by mixing these bodies with lignic acid or lignin sulfonic acid salts, that is, sum cellulose waste liquor. In this way, namely by evaporating these pastes, one can also produce non-explosive solid products. For example, one obtains a paste that can be shipped and is no longer explosive even when it is artificially completely dried out, if dinitrophenol sodium or the saline dinitrophenol sodium, as obtained by reacting dinitrochlorobenzene with sodium hydroxide, is used with approximately the same amount or the I 1 Z 2 times the amount or less of about 8% sulphite cellulose waste liquor mixed with or without the addition of soda, caustic soda, etc. By drying at a temperature that is not too high, e.g. in a vacuum, solid products are obtained which, even when heated abruptly, do not explode, but only If the explosibility of nitro bodies is not to be completely abolished, but only to be tuned down, then considerably less lignosulfonic acid salt is added.
Die Sulfitzelluloseablauge hat vielleicht infolge ihrer zusammenbackenden klebrigen Beschaffenheit die Eigenschaft, die Beweglichkeit der Einzelteilchen des betreffenden explosiblen Körpers und damit die Ubertragbarkeit der Zündung eines solchen Einzelteilchens auf ein anderes herabzusetzen.The sulphite cellulose liquor may have a sticky nature due to its caking the property, the mobility of the individual particles of the explosive in question Body and thus the transferability of the ignition of such a single particle to a to belittle other things.
Mit dem gekennzeichneten Verfahren ist auch gleichzeitig eine wertvolle Verwendung für die sonst als lästiges Abfallprodukt angesehene Sulfitzelluloseablauge geschaffen. Die auf diese Weise z. B. aus den Dinitrophenolsalzen erhaltenen Pasten zeichnen sich auch durch eine sehr gute Löslichkeit aus; sie trocknen ferner nur sehr schwer ein, ein für den Verkauf in billigen. Packungen ebenfalls nicht unwesentliches Moment. Auch erweisen sich die Pasten als völlig haltbar, indem die ligninsulfosauren Salze bei gewöhnlicher bzw. nur schwach erhöhter Temperatur sich als indifferent gegen Nitrokörper gezeigt haben.The marked process is also a valuable use at the same time created for the sulphite cellulose liquor, which is otherwise regarded as an annoying waste product. The in this way z. B. pastes obtained from the dinitrophenol salts stand out also characterized by a very good solubility; they are also very difficult to dry up for sale in cheap. Packs are also a not insignificant moment. Also turn out The pastes prove to be completely durable by adding the lignosulfonic acid salts to the ordinary or only slightly increased temperature is shown to be indifferent to nitro bodies to have.
Das vorgenannte Verfahren kann für samt-The aforementioned method can be used for all
