Description
Verfahren zur Herstellung eines Imprägnierungsmittels für Holz und ähnliche Faserstoffe Die Erfindung bezieht sich auf ein Herstellungsverfahren für ein Imprägnierungsmittel zum Konservieren von Holz und andern Stoffen, die gegen Fäulnis geschützt werden sollen.Process for the preparation of an impregnating agent for wood and Similar fibrous materials The invention relates to a manufacturing method for an impregnation agent for the preservation of wood and other substances that act against Rot should be protected.
Es sind bereits Konservierungsmittel zum Imprägnieren von Holz bekannt, die durch eine ammoniakalische Lösung gebildet werden, die giftige Metallsalze, wie Kupfer-, Zink-, Quecksilber-, Arsensalze, mit Zusatz von Phenol, Kresol oder deren Homologen. enthält.Preservatives for impregnating wood are already known, which are formed by an ammoniacal solution, the poisonous metal salts, such as copper, zinc, mercury, arsenic salts, with the addition of phenol, cresol or their homologues. contains.
Ein bei der Herstellung dieser Produkte sich ergebender wichtiger Nachteil besteht in Satz- oder Schlammbildungen. Dieser Nachteil zeigt sich nicht nur bei der Herstellung der Lösung selbst, sondern auch nachher, wenn die Lösung sich selbst überlassen wird.An important one resulting in the manufacture of these products The disadvantage is the formation of sediments or sludge. This disadvantage does not show up only during the preparation of the solution itself, but also afterwards when the solution is left to itself.
Vermutlich «.erden diese Schlammablagerungen durch eine Oxydation der Phenole verursacht, die entweder durch Wirkung des Sauerstoffs der Luft bei der Fabrikation hervorgerufen wird oder nachher durch eine Selbstoxydation der Phenole, durch die Chirionverbindungen entstehen, die mit den in der Lösung enthaltenen Metallsalzen reagieren und so zu den Schlammniederschlägen führen.Presumably «these sludge deposits are grounded by oxidation the phenols caused either by the action of the oxygen in the air caused during manufacture or afterwards by self-oxidation of the phenols, through the chirion compounds arise with the metal salts contained in the solution react and thus lead to the sludge precipitation.
Das den Gegenstand der Erfindung bildende Verfahren, das diesem Nachteil abhelfen soll, besteht nun darin, daß der durch eines der bekannten Verfahren erhaltenen Imprägnierungslösung ein Stoff zugesetzt wird, der die Chinone reduziert und durch seine antioxygenen Eigenschaften die Selbstoxydation der Phenole verhindert, ohne zusätzliche Reaktionen mit den in der Lösung enthaltenen Stoffen herbeizuführen.The object of the invention, this disadvantage to remedy, is that the obtained by one of the known methods Impregnation solution is added a substance that reduces the quinones and through its antioxidant properties prevent the self-oxidation of phenols without bring about additional reactions with the substances contained in the solution.
Es ist festgestellt worden, daß man unter die Stoffe, die sich hierfür besonders gut eignen, die Sulfite, Disulfite, Hyposulfite, Hydrosulfite, Metadisulfite und andere Stoffe, die gleichartige Eigenschaften besitzen, und zwar besonders das Natriumhydrosulfit rechnen kann.It has been found that one of the substances that can be used for this is Particularly suitable are the sulfites, disulfites, hyposulfites, hydrosulfites, metadisulfites and other substances that have similar properties, especially that Sodium hydrosulfite can count.
Der Zusatz eines dieser Stoffe zu der Lösung, sei es vor oder nach dem Zusetzen der Phenole, oder zu den Phenolen selbst vor dem Mischen gibt die Möglichkeit, die Schlammbildungen vollständig zu vermeiden und macht die Lösung sicher haltbar, wenn man sie unter Luftabschluß aufbewahrt.The addition of any of these substances to the solution, be it before or after adding the phenols, or to the phenols themselves before mixing, gives the possibility of completely avoiding the formation of sludge and making the solution safe and durable, if you keep them in the absence of air.
Im Falle einer Lösung auf der Basis von frisch zubereitetem Zinkformiat (3 bis 40/0), die Kupfer (5 bis 70/0), Ammoniak (65%) -und Phenol (8 bis i o o/ o ) enthält, kann man das gewünschte Ergebnis bereits durch Zusatz von Natriumhydrosulfit im Verhältnis von etwa o, i bis 10/6 erzielen. Geht man von einer ammoniakalisch gemachten Auflösung von Messing in Säuren (4 bis 12 %) aus, der man Kresol (4 bis 8%) und Wasser zugesetzt hat, so genügt gleichfalls ein Zusatz von o, i bis i % Natriumhydrosulfit.In the case of a solution based on freshly prepared zinc formate (3 to 40/0), the copper (5 to 70/0), ammonia (65%) and phenol (8 to i o o / o), you can achieve the desired result by adding sodium hydrosulfite achieve in a ratio of about 0.1 to 10/6. If you think of one ammoniacal made dissolution of brass in acids (4 to 12%), which one If cresol (4 to 8%) and water have been added, an addition of is also sufficient o, i to i% sodium hydrosulfite.
Statt das Natriumhydrosulfit der fertigen Lösung zuzusrtzen, kann man es auch beispielsweise in einer Menge von 2% der ammoniakalisch gemachten Auflösung von Messing in Säuren zusetzen und hierauf Kresol und Wasser hinzufügen.Instead of adding the sodium hydrosulfite to the finished solution, you can it can also be used, for example, in an amount of 2% of the solution made ammoniacal add brass in acids and then add cresol and water.
Schließlich kann das Hydrosulfit unmittelbar dem Kresol, z. B. in einer Menge von io%, und die so erhaltene Lösung der gewöhnlichen ammoniakalischen Metallsalzlösung zugesetzt werden.Finally, the hydrosulfite can be added directly to the cresol, e.g. Am an amount of 10%, and the solution thus obtained is the usual ammoniacal Metal salt solution can be added.
Es versteht sich von selbst, daß die oben angegebenen Verhältnisse nur beispielsweise gedacht sind und sich in weiten Grenzen verändern können, je nach der Auswahl des zugesetzten reduzierenden Stoffes und der Art der Impräbnierungslösung, von der ausgegangen wird.It goes without saying that the ratios given above are only intended for example and can change within wide limits, ever according to the selection of the added reducing substance and the type of impregnation solution, which is assumed.
