Description

Verfahren zum Konservieren von Holz. Es wurde gefunden, daß die löslichen Salze von Oxynitrodiphenylmethanen außer einer überaus starken Wirkung gegen holzzerstörende Pilze auch die Eigenschaft haben, von der Holzfaser ganz orler nahezu unauswaschhar festgehalten zu werden. Sie eignen sich daher in hervorragender Weise zum Imprägnieren von Holz.Process for preserving wood. It has been found that the soluble Salts of Oxynitrodiphenylmethanen besides an extremely strong effect against wood-destroying Mushrooms also have the property of being almost indelible from the wood fiber to be held. They are therefore ideally suited for impregnation of wood.

Beispielsweise tränkt man Kiefernholz mit einer Lösung von 1,5 Teilen 4-4.'-DiOxy-3-3'-dinitrodiphenylmethan in iooo Teilen Wasser und der nötigen Menge Natronlauge. Bringt man das so behandelte und wieder getrocknete Holz in Wasser, so löst sich nur eine geringe Menge an der Oberfläche eingetrockneten Salzes, während bei weiterem anhaltenden Auslaugen keine merklichen Mengen mehr in Lösung gehen und das Holz seine Widerstandsfähigkeit gegen Pilzbefall behält.For example, pine wood is soaked in a solution of 1.5 parts 4-4 .'-DiOxy-3-3'-dinitrodiphenylmethane in 1,000 parts of water and the necessary amount Caustic soda. If you put the treated and dried wood in water, so only a small amount of dried salt dissolves on the surface while if the leaching continues, no noticeable amounts will go into solution and the wood retains its resistance to fungal attack.

An Stelle des Natronsalzes der obengenannten Verbindung kann man auch lösliche Salze des 4-Oxy-3-nitrodipheiiylinethans, des ?-a'-Dioxy-5-5'-dinitrödiphenylmethans oder anderer im Kern methylierter oder halogenierter Oxynitrodiphenylmethane verwenden; gegebenenfalls kann man diesen andere pilz-und insektentötende Mittel zusetzen.Instead of the sodium salt of the abovementioned compound, it is also possible to use soluble salts of 4-oxy-3-nitrodipheiiylinethane, of? -a'-dioxy-5-5'-dinitrodiphenylmethane or use other core-methylated or halogenated oxynitrodiphenylmethanes; if necessary, other fungicides and insecticides can be added to them.
