Es ist natürlich wünschenswert, möglichst wenig zwecklose oder schädlich wirkende Ionen in das Holz zu bringen, weshalb man sie durch doppelte Umsetzung und Fällung aus konzentrierter Lösung vorher ausfällen kann. So löst man z. B. 7'5 GewichtsteileAluminiumsulfat und 10 Gewichtsteile Kalziumbichromat in Wasser und entfernt den herausfallenden unlöslichen schwefelsauren Kalk. Oder man löst 45 Gewichtsteile Kupfersulfat und 55 Gewichtsteile Kaliumbichromat in wenig Wasser und scheidet das ausfallende Kaliumsulfat ab. Freilich werden in beiden Fällen die schädlichen Salze nicht vollständig entfernt.
Versuche haben gezeigt, dass man bei Verwendung von Zerbichromat, Kupferbichromat, einem Gemenge dieser Salze und von Chromsäure allein die besten Resultate erzielt.
PATENT-ANSPRÜCHE :
1. Verfahren zum Imprägnieren oder Anstreichen von Holz, Pappe, Geweben und dgl.
Materialien gegen Fäulnis unter Anwendung von Lösungen einerseits der Bichromate und Chromate der Alkalien, des Ammoniaks und der alkalischen Erden, andererseits der Salze von Kupfer, Zer, Zink, Aluminium, Chrom (oxyd), Mangan und Eisen (oxyd), dadurch gekennzeichnet, dass ein oder mehrere Körper der ersten Gruppe mit einem oder mehreren Körpern der zweiten Gruppe zusammen in einer Lösung angewendet werden, welche sauer bis höchstens neutral reagiert (also ohne Zusatz von überschüssigem Alkali), wodurch das Ausfallen basischer Niederschläge vermieden und die Bildung schwer löstieher Niederschlage von basischen Chromaten erst im Holz und dgl. bewirkt wird (z. B. 1% Kupfervitriol mit 1% Kaiiumbichromat oder 0'44% Kalium-

It is of course desirable to introduce as few useless or harmful ions as possible into the wood, which is why they can be precipitated beforehand by double conversion and precipitation from concentrated solution. How to solve z. B. 7'5 parts by weight of aluminum sulfate and 10 parts by weight of calcium dichromate in water and removes the insoluble sulphate of lime that falls out. Or 45 parts by weight of copper sulphate and 55 parts by weight of potassium dichromate are dissolved in a little water and the potassium sulphate which precipitates is separated off. Of course, in both cases the harmful salts are not completely removed.
Tests have shown that the best results are obtained when using bischromate, copper dichromate, a mixture of these salts and chromic acid alone.
PATENT CLAIMS:
1. Method for impregnating or painting wood, cardboard, fabrics and the like.
Materials against putrefaction using solutions on the one hand of the bichromates and chromates of alkalis, ammonia and alkaline earths, on the other hand of the salts of copper, cerium, zinc, aluminum, chromium (oxide), manganese and iron (oxide), characterized in that one or more bodies of the first group can be used together with one or more bodies of the second group in a solution which reacts acidic to at most neutral (i.e. without the addition of excess alkali), which avoids the formation of basic precipitates and the formation of difficult-to-dissolve precipitates basic chromate is only effected in wood and the like (e.g. 1% vitriol with 1% potassium dichromate or 0'44% potassium
