Zusatz zum Patente 226975 vom 8. Mai 1908.Addendum to patent 226975 from May 8, 1908.
Patentiert im Deutschen Reiche vom 23. Mai 1908 ab. Längste Dauer: 7.Mai 1923.Patented in the German Empire on May 23, 1908. Longest duration: May 7, 1923.
Die vorliegende Erfindung hat eine weitere Ausbildung des Verfahrens nach Patent 226975 zum Gegenstande.The present invention takes a further development of the method of patent 226975 to the subject.
Die zum Imprägnieren des Holzes hier verwendeten Flüssigkeiten enthalten an Stelle der im Hauptpatent benutzten Metallverbindungen Schwefelarsen, Arsensäure, arsenige Säure,. Antimonsäure, antimonige Säure, Chromsäure oder Gemenge der .genannten Verbindungen in ammoniakalischer Lösung. Diese Zusammensetzung der Imprägnierflüssigkeiten macht sie besonders dort geeignet, wo die damit imprägnierten Hölzer o. dgl. mit Seewasser in Berührung kommen, also besonders zum Imprägnieren von zum Schiffsbau bestimmtem Holz. Eine solche Imprägnierung bietet auch einen besonderen Schutz gegen den Angriff von Tieren aller Art, so z. B. auch gegen Insekten, wie weiße Ameisen u. dgl. ·The liquids used here to impregnate the wood contain instead of the Metal compounds used in the main patent: arsenic sulfur, arsenic acid, arsenous acid. Antimonic acid, antimony acid, chromic acid or mixtures of the compounds mentioned in ammoniacal solution. This is the composition of the impregnation liquids they are particularly suitable where the wood or the like impregnated with seawater come into contact, especially for the impregnation of goods intended for shipbuilding Wood. Such an impregnation also offers special protection against the attack of animals of all kinds, such as B. also against insects such as white ants and the like.
Beim Lagern oder Erwärmen der so imprägnierten Gegenstände entweicht der Überschuß des Ammoniaks sowie auch der größte Teil des gebundenen Ammoniaks, während die Säuren oder die andere an Ammoniak gebundene wirksame Substanz in mehr oder weniger unlöslicher Form in dem imprägnierten Gegenstand zurückbleibt.When the objects so impregnated are stored or heated, the excess escapes of ammonia as well as most of the bound ammonia, while the acids or the other bound to ammonia active substance remains in more or less insoluble form in the impregnated article.
Die Wirkung der Imprägniermittel kann durch Zusatz anderer wasserlöslicher oder mit Wasser emulgierbarer bekannter Imprägniermittel modifiziert oder verstärkt werden.The effect of the impregnation agent can be achieved through the addition of other water-soluble or with Water-emulsifiable known impregnating agents are modified or strengthened.
Außer zur Imprägnierung von Holz können die Flüssigkeiten selbstverständlich auch zur Imprägnierung anderer Gegenstände, beispielsr weise für Papier, Pappe u. dgl., benutzt werden. In addition to impregnating wood, the liquids can of course also be used for Impregnation of other objects, e.g. for paper, cardboard and the like., Can be used.
Es ist zwar bekannt, sowohl Arsensäure als auch arsenige Säure in Form ihrer beständigen wasserlöslichen oder ihrer wasserunlöslichen Salze zur Holzkonservierung zu verwenden. Hierbei kommen aber die genannten Säuren nicht als solche zur Wirkung, sondern bleiben im Holze entweder in Form ihrer wasserlöslichen Alkalisalze bestehen oder werden durch die gleichzeitige oder nachträgliche Behandlung des Holzes mit Metallsalzen im Holz in die unlöslichen arsensauren bzw. arsenigsauren Metallsalze umgewandelt.While it is known to have both arsenic acid and arsenous acid in the form of their persistent to use water-soluble or their water-insoluble salts for wood preservation. Here, however, the acids mentioned do not have an effect as such, but remain in wood either exist in the form of their water-soluble alkali salts or are through the simultaneous or subsequent treatment of the wood with metal salts in the wood in the insoluble arsenic or arsenic metal salts.
Nach vorstehendem Verfahren werden zwar die leicht löslichen Ammonsalze der Arsensäure bzw. arsenigen Säure verwendet, doch werden diese Salze bei Anwendung von Wärme sehr leicht unter Abspaltung von Ammoniak zersetzt, so daß die freien Säuren zurückbleiben, die dann als solche zur Wirkung kommen.According to the above process, the easily soluble ammonium salts of arsenic acid are obtained or arsenic acid is used, but these salts become very much with the application of heat easily decomposed with elimination of ammonia, so that the free acids remain, which then come into effect as such.
Auch die Anwendung von chromsaurem Kali als Imprägnierungsmittel ist an sich bekannt, doch verbleibt auch hier dieses lösliche Salz als solches im Holze, während bei der Anwendung von chromsaurem Ammon gemäß vorliegender Erfindung durch Zersetzung Chromhydroxyd gebildet wird.The use of potassium chromate as an impregnating agent is also known per se, but here, too, this soluble salt remains as such in the wood, while with the Use of chromic acid ammonium according to the present invention by decomposing chromium hydroxide is formed.
