KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
In dem Hauptpatent 28411g ist ein Verfahren zur Herstellung von in kaltem Wasser leicht löslichen Gerbstoffpräparaten aus Gerbstoffextrakten, welche unlösliche bzw. schwerlösliche Bestandteile enthalten, beschrieben, darin bestehend, daß man die fertigen, eingedickten Gerbstoffextrakte bzw. deren unlösliche oder schwerlösliche Bestandteile, oder die zwecks Herstellung der Extrakte einzudickenden dünnen Brühen mit solchen wasserlöslichen, in ihrem Molekül eine oder mehrere saure salzbildende Gruppen außer den Hydroxylgruppen enthaltenden Verbindungen behandelt, wie sie aus aromatischen Oxyverbindüngen durch Kondensation mit Formaldehyd oder Formaldehyd entwickelnden oder wie dieser reagierenden Stoffen erhältlich sind, oder mit solchen wasserlöslichen Verbindungen versetzt, wie sie durch Kondensation von Phenolsulfosäuren oder deren Homologen für sich erhalten werden können.There is one method in main patent 28411g for the production of tanning preparations from tannin extracts, which are easily soluble in cold water, which contain insoluble or sparingly soluble constituents, consisting in the fact that the finished, thickened Tanning extracts or their insoluble or sparingly soluble components, or the thin broths to be thickened for the production of the extracts with such water-soluble, in their molecule one or more acidic salt-forming groups apart from the hydroxyl groups containing compounds treated as they are from aromatic Oxyverbindüngen can be obtained by condensation with formaldehyde or substances that evolve or react with formaldehyde, or mixed with such water-soluble compounds as they are by condensation of Phenolsulfonic acids or their homologues can be obtained for themselves.
Es wurde nun gefunden, daß man diese im Hauptpatent 284119 genannten Produkte ganz generell durch andere synthetische, gerbende Eigenschaften besitzende Verbindungen, insbesondere durch diejenigen Stoffe/ deren Verwendung als Gerbstoffe in den Patenten 281484 und 290965 beansprucht ist, ersetzen kann, wobei die im Patent 292531 beschriebenen Produkte ausgenommen sein sollen.It has now been found that these products mentioned in the main patent 284119 can be used generally through other synthetic, tanning properties possessing compounds, in particular through those substances / their use as tanning agents in the patents 281484 and 290965 is claimed, can replace that in patent 292531 products described should be excluded.
Die Ausführungsmöglichkeiten des Verfahrens sind hier die gleichen wie bei dem Verfahren des Hauptpatentes.The execution options of the method are the same here as in the case of the method of the main patent.
2000 Teile Quebrachoextrakt fest werden mit 2000 Teilen Wasser erwärmt und hierzu allmählich 2000 Teile der nach Beispiel 2 des Patentes 290965 erhältlichen Paste des anneutralisierten Einwirkungsproduktes von Formaldehyd auf Naphtalinsulfosäure unter Erwärmen zugefügt. Man erhält eine klare Lösung, die sich beliebig mit Wasser verdünnen läßt, ohne trüb zu werden. Diese Lösung ist nach der Verdünnung direkt zum Gerben verwendbar. 2000 parts of quebracho extract solid are heated with 2000 parts of water and for this purpose gradually 2000 parts of the paste obtained according to Example 2 of Patent 290965 of the neutralized Product of action of formaldehyde on naphthalene sulfonic acid added with heating. A clear solution is obtained, which can be diluted with water as desired without becoming cloudy. This solution is after the dilution can be used directly for tanning.
100 Teile fester Quebrachoextrakt werden gepulvert und in etwa 100 Teile einer warmen, konzentrierten Lösung des nach Beispiel II des Patentes 281484 erhältlichen anneutralisierten Einwirkungsproduktes von Chlorschwefel auf Rohkresolsulfosäure unter Rühren eingetragen; man erhält eine klare Lösung, die sich mit kaltem Wasser verdünnen läßt, ohne sich zu trüben.100 parts of solid quebracho extract can be used powdered and in about 100 parts of a warm, concentrated solution of the example II of patent 281484 available anneutralized Product of the action of chlorosulphur on raw cresol sulphonic acid entered with stirring; you get a clear one Solution that can be diluted with cold water without becoming cloudy.
Analog verfährt man bei Verwendung anderer schwer löslicher Extrakte, wie z. B. Mangrove, Kastanie, sowie anderer lösender Mittel der eingangs gekennzeichneten Art.The same procedure is followed when using other sparingly soluble extracts, such as. B. Mangrove, chestnut, as well as other solvents of the kind identified at the beginning.
