Verfahren zur Herstellung von nichtexplosiblen besonders für die Zwecke der Holzkpnservierung geeigneten Präparaten aus Nitrophenole.
Die in neuerer Zeit für die Zwecke der Holzkonservierung in Vorschlag gebrachten, mit anorganischen Basen abgesättigten Mono-, Di- und Polynitroverbindungen, insbesondere die Di-und Trinitrophenol-und-kresolsalze, haben bekanntlich den Nachteil, dass sie beim Eintrocknen stark zur Explosivität neigen.
Diesen Übelstand hat man dadurch zu beseitigen versucht, dass man den genannten Nitroverbindungen indifferente Stoffe, wie Glyzerin, Seife oder Sulfitzelluloseablauge, die als Hauptbestandteil ligninsulfosaure Salze enthält, zusetzte.
Für die Zwecke der Holzkonservierung war damit jedoch ein neuer Nachteil in der.
Richtung verbunden, dass durch den Zusatz dieser in fungicider Hinsicht völlig unwirksamen
EMI1.1
unerheblich geschwächt wurde.
Dieser Nachteil kann nun nach vorliegender Erfindung in der Weise vermieden werden, dass man die genannten Nitroverbindungen mit Stoffen versetzt, die sowohl die Fähigkeit besitzen, die Explosivität der Nitroverbindungen aufzuheben oder herabzumindern, als auch
EMI1.2
Als geeignet hierzu haben sich die für diesen Zweck noch nicht in Vorschlag gebrachten sulfosauren Salze aromatischer Kohlenwasserstoffe und ihrer Derivate (Halogen, Hydroxyl, Nitroverbindungen usw. ) sowie Mischungen der genannten Salze erwiesen.
In Betracht kommen beispielsweise naphthalinsulfosaures Zink, Calcium, Magnesium oder phenolsulfosaures Natrium, Calcium usw. bzw. die bei der Darstellung der Sulfosäuren aus Rohnaphthalin, Rohantrazen, Rohphenathren, Rohkarbazol, Rohphenol, Rohkresol usw. sowie Gemischen, wie sie im Teeröl vorliegen, durch Absättigen mit Zinkoxyd, Magnesia, Natronlauge usw. direkt erhaltenen Lösungen.
Die Mischung erfolgt derart, dass beispielsweise auf i Teil Di-oder Trinitrophenol oder-kresonatrium i bis I0 Teile naphthalinsulfosaures Zink, phenolsulfosaures Natrium oder Gemische aller dieser Stoffe zugesetzt werden. Soll die Explosivität nicht aufgehoben, sondern nur vermindert werden, so wird der Zusatz von sulfosauren Salzen aromatischer Kohlenwasserstoffe und ihrer Derivate entsprechend eingeschränkt.
Gegenüber der Deutschen Reichspatentschrift Nr. 219942, welche die Verwendung hydroxylfreier Nitrokörper, die keine Salze zu bilden vermögen, vorsieht und gegenüber der Deutschen Reichspatentschrift Nr. 219893, welche mit organischen Basen abgesättigte Nitrokörper benutzt, unterscheidet sich vorliegendes Verfahren dadurch, dass dort Nitrokörper verwendet werden, die nach den Angaben der Patentschriften schon an und für sich unexplosiv sind, so dass der Zusatz eines anderen Holzkonservierungsmittels keine weitere explosionshemmende Wirkung ausüben kann, während im vorliegenden Falle mit anorganischen Basen abgesättigte Nitroverbindungen in Frage kommen,
die im Gegensatz zu den vorhin genannten Verbindungen stark explosiv sind und durch den Zusatz der sulfosauren
<Desc/Clms Page number 2>
Salze aromatischer Kohlenwasserstoffe und ihrer Derivate erst explosionssicher gemacht werden sollen.

Process for the production of non-explosive preparations from nitrophenols, particularly suitable for the purposes of wood preservation.
The mono-, di- and polynitro compounds saturated with inorganic bases, in particular the di- and trinitrophenol and cresol salts, which have recently been proposed for the purpose of wood preservation, are known to have the disadvantage that they have a strong tendency to be explosive when they dry out.
Attempts have been made to eliminate this deficiency by adding inert substances such as glycerine, soap or sulphite cellulose liquor, which contains lignosulphonic acid salts as the main component, to the nitro compounds mentioned.
For the purposes of wood preservation, however, this was a new disadvantage in the.
Direction connected that by the addition of this in fungicider terms completely ineffective
EMI1.1
has been weakened insignificantly.
This disadvantage can now be avoided according to the present invention in such a way that the nitro compounds mentioned are mixed with substances which both have the ability to neutralize or reduce the explosiveness of the nitro compounds and also
EMI1.2
The sulfonic acid salts of aromatic hydrocarbons and their derivatives (halogen, hydroxyl, nitro compounds, etc.) and mixtures of the salts mentioned have proven suitable for this purpose, which have not yet been proposed for this purpose.
For example, naphthalenesulfonate zinc, calcium, magnesium or phenolsulfonate sodium, calcium etc. or those in the representation of the sulfonic acids from raw naphthalene, raw anthracene, raw phenathene, raw carbazole, raw phenol, raw cresol etc., as well as mixtures such as are present in tar oil, by saturation solutions obtained directly with zinc oxide, magnesia, caustic soda, etc.
Mixing is carried out in such a way that, for example, 1 to 10 parts of naphthalenesulfonate zinc, phenolsulfonate sodium or mixtures of all of these substances are added to i part of di- or trinitrophenol or cresonodium. If the explosiveness is not to be eliminated, but only to be reduced, the addition of sulfonic acid salts of aromatic hydrocarbons and their derivatives is restricted accordingly.
Compared to the German Reichspatentschrift No. 219942, which provides for the use of hydroxyl-free nitro bodies that are unable to form salts, and compared to the German Reich patent specification No. 219893, which uses nitro bodies saturated with organic bases, the present process differs in that nitro bodies are used there which, according to the information in the patent specifications, are inherently non-explosive, so that the addition of another wood preservative cannot have any further explosion-inhibiting effect, whereas in the present case nitro compounds saturated with inorganic bases are possible,
which, in contrast to the compounds mentioned above, are highly explosive and due to the addition of sulphonic acids
<Desc / Clms Page number 2>
Salts of aromatic hydrocarbons and their derivatives should only be made explosion-proof.
