Description
Holzimprägnierungsmittel. Die Verwendung eines Gemisches von fettsaurem Alkali (Seife) und freien Dini- trophenolen für Holzkonservierungszwecke ist bekannt. Während die freien- Dinitrophenole in Wasser ganz unzureichend löslich sind, lösen sie sich in Wasser, welches fettsaures Alkali enthält, zureichend. Es ist weiter bekannt, die fettsauren Alkalien vorteilhaft durch die billigern Alkalifluoride zu ersetzen.
Versuche zeigten, dass es höchst vorteil haft ist, dem für Holzimprägnierungszwecke an sich bekannten Gemenge eines freien Dinitrophenols mit Fluoralkalien ein Anti- monsalz, zum Beispiel Brechweinstein oder Antimonfluorid-Doppelsalze zuzusetzen. Dieser Zusatz ist auch dann von Vorteil, wenn man statt einem freien Dinitrophenol ein Salz eines Dinitrophenols mit einem Fluoralkali gemengt verwendet.
Auch eine geringe Menge an An- timonsalz ist bereits von Vorteil. So kann man zum Beispiel folgende Mischung ver wenden: Dinitrophenol 18'/o, Fluornatrium. 80"/o, Doppelsalz bestehend aus Antimonfluorid und Chlornatrium 2<B>0/0.</B>
Die Vorteile des Zusatzes- eines Antimon- salzes sind ein besserer Schutz der Metallbe standteile.<B>Es</B> entsteht eine fest haftende Schutzschicht, vielleicht infolge Abscheidung metallischen Antimons. Ferner beizen Anti- monsalze das Holz. Dadurch wird die Haft barkeit der beiden andern Bestandteile er höht.
Wood impregnation agents. The use of a mixture of fatty acid alkali (soap) and free dinitrophenols for wood preservation purposes is known. While the free dinitrophenols are quite insufficiently soluble in water, they dissolve sufficiently in water which contains fatty acid alkali. It is also known to advantageously replace the fatty acid alkalis by the cheaper alkali fluorides.
Tests have shown that it is extremely advantageous to add an antimony salt, for example emetic tartar or antimony fluoride double salts, to the mixture of free dinitrophenol with fluoroalkali, which is known per se for wood impregnation purposes. This addition is also advantageous if, instead of a free dinitrophenol, a salt of a dinitrophenol is used mixed with a fluoroalkali.
A small amount of antimony salt is also an advantage. For example, the following mixture can be used: dinitrophenol 18%, fluorosodium. 80 "/ o, double salt consisting of antimony fluoride and sodium chloride 2 <B> 0/0. </B>
The advantages of adding an antimony salt are better protection of the metal components. <B> It </B> creates a firmly adhering protective layer, perhaps as a result of the deposition of metallic antimony. Furthermore, antimony salts stain the wood. This increases the adhesion of the other two components.
