Description
Patentiert im Deutschen Reiche vom 12. Dezember 1926 ab. Es hat sich gezeigt, daß die Molekülverbindungen, die man aus zahlreichen Nitroderivaten der aromatischen Reihe mit aromatischen Aminen erhalten kann, eine außerordentlich starke Giftwirkung gegenüber holzzerstörenden Pilzen aufweisen, welche die Summenwirkung ihrer Einzelbestandteile bei weitem übertrifft. Besonders zeichnen sich in dieser Beziehung die in der Literatur noch nicht beschriebenen Molekülverbindungen aus i-2-4-Dinitroclilorbenzol mit aromatischen Aminen aus. Wenn man die: genannten Verbindungen hölzernen Gegenständen einverleibt, werden diese gegen Fäulniserreger geschützt; infolge der hohen Toxität der Verbindungen genügen schon geringe Zufuhren, um diese Wirkung zu erreichen, und andererseits ist im Zusammenhang mit der geringen Wasserlöslichkeit und der Schwerflüchtigkeit der neuen konservierenden Stoffe der Schutz des Holzes ein sehr lang anhaltender.Patented in the German Empire on December 12, 1926. It has showed that the molecular compounds obtained from numerous nitro derivatives of the aromatic series can be obtained with aromatic amines, an extraordinarily strong one Have poisonous effects on wood-destroying fungi, which have the cumulative effect of its individual components by far. Particularly stand out in this Relationship from the molecular compounds not yet described in the literature i-2-4-Dinitroclilorbenzol with aromatic amines from. If you have the: mentioned connections incorporated into wooden objects, these are protected against putrefactive agents; As a result of the high toxicity of the compounds, even small intakes are sufficient for them To achieve effect, and on the other hand is in connection with the low water solubility and the low volatility of the new preservatives, the protection of the wood a very long lasting one.
In den meisten Fällen ist es notwendig, die Konservierungsmittel in einem geeigneten Lösungsmittels in das Holz einzuführen; als solches verwendet man mit Vorteil ein schwerflüchtiges 01, das entweder an sich keine fungiziden Eigenschaften hat, wie paraffinhaltiges Erdöl, oder selbst ebenfalls hoch konservierend wirkt, wie Steinkohlenteeröl und andere phenolhaltige Öle. Im letzteren Fall wird die Wirkung des Öles durch den Zusatz der neuen Konservierungsmittel gesteigert, und man ist in der Lage, mit einer geringeren Menge (11 als bisher üblich einen gleich guten Schutz des Holzes zu bewirken.In most cases it is necessary to introduce the preservatives into the wood in a suitable solvent; as such is advantageously used a low volatility 01 that either no fungicidal properties per se, like paraffinic oil, or even also high acts as a preservative, such as coal tar and other phenol-containing oils. In the latter case, the effect of the oil is increased by the addition of the new preservative, and it is possible to protect the wood with a smaller amount (11 than has been the case up to now).
Als Beispiele seien folgende Doppelverbindungen angeführt, zugleich mit den Konzentrationen, in denen diese auf einem künstlichen -Nährboden das Wachstum des Hausschwammes Merulius lacrvtnans verhindern: i-2-d.-Ditiitrochlor benzol-a-N aphthvlamin o,oo75 Prozent, i-2-d.-Ditiitrochlor benzol-ß-Naphthvlamin o,ood Prozent, i-2-4-Dinitrochlorbenzol-Benzidin o,oo8 Prozent.The following double compounds are given as examples, at the same time with the concentrations in which these grow on an artificial nutrient medium of the dry rot Merulius lacrvtnans: i-2-d.-ditiitrochlor benzene-a-N aphthvlamin o, oo75 percent, i-2-d.-ditiitrochlor benzene-ß-naphthvlamin o, ood percent, i-2-4-Dinitrochlorobenzene-Benzidine 0.08 percent.
