Description

Verfahren zur Herstellung von in kaltem Wasser leicht löslichen Gerbstoffpräparaten. Durch das Hauptpatent 284119 ist ein Verfahren zur Herstellung von in kaltem Wasser leicht löslichen Gerbstoffpräparaten aus Gerbstoffextrakten, welche unlösliche bzw. schwerlösliche Bestandteile enthalten, geschützt, 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 Oxyverbindungen 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.Process for the production of tanning preparations which are easily soluble in cold water. The main patent 284119 describes a process for the production of cold water Easily soluble tannin preparations made from tannin extracts, which are insoluble or contain poorly soluble components, protected, consisting in the fact that the finished, thickened tannin extracts or their insoluble or sparingly soluble components or the thin broths with them to be thickened for the purpose of making the extracts water-soluble, one or more acidic salt-forming groups in their molecule, except for the compounds containing hydroxyl groups, treated as they are from aromatic Oxy compounds evolving through condensation with formaldehyde or formaldehyde or how these reacting substances are available, or with such water-soluble substances Compounds added, such as those caused by the condensation of phenol sulfonic acids or their Homologues can be obtained for themselves.

In dem Zusatzpatent 299857 ist dieses Verfahren dahin abgeändert, daß man an Stelle der im Hauptpatent verwendeten Produkte andere synthetische, gerbende Eigenschaften besitzende Verbindungen, insbesondere diejenigen, deren Verwendung zum Gerben tierischer Häute durch die Patente 28148.1 und 29o965 geschützt ist benutzen kann.In the additional patent 299857 , this process is modified so that, instead of the products used in the main patent, other synthetic compounds with tanning properties can be used, especially those whose use for tanning animal hides is protected by patents 28148.1 and 29o965.

Nach dem Verfahren des Zusatzpatents 299988 werden dieselben löslichmachenden Verbindungen unmittelbar auf die gerbende Stoffe enthaltenden Hölzer, Rinden usw. zur Einwirkung gebracht.According to the process of the additional patent 299988 , the same solubilizing compounds are brought into action directly on the wood, bark, etc. containing tanning substances.

Es wurde nun gefunden, daß man statt der bisher verwendeten löslichmachenden Stoffe, die sämtlich gerbende Eigenschaften besitzen, auch die Sulfosäuren oder sulfosauren Salze von im Kern durch die Propyl- oder Isopropylgruppe substituiertenaromatischenKohlenwasserstoffen, insbesondere des Naphthalins bzw. anderer mehrkerniger Kohlenwasserstoffe, von denen gerbende Eigenschaften nicht bekannt sind, benutzen kann.It has now been found that instead of the solubilizing agents previously used Substances that all have tanning properties, including sulfonic acids or sulfonic acid salts of aromatic hydrocarbons substituted in the core by the propyl or isopropyl group, in particular of naphthalene or other polynuclear hydrocarbons, of which tanning properties are not known.

Beispiel: 6o Teile fester Quebrachoextrakt werden in der Wärme mit einer konzentrierten wäßrigen Lösung von 1o Teilen isopropylnaphthalinsulfosaurem Natrium versetzt. Das Produkt bleibt beim Erkalten völlig gelöst, läßt sich mit V"asser beliebig verdünnen und eignet sich vorzüglich zum Gerben.Example: 6o parts of solid quebracho extract are added to the heat a concentrated aqueous solution of 10 parts of isopropylnaphthalenesulfonic acid Sodium added. The product remains completely dissolved when it cools, can be used with V "ater can be diluted as required and is ideally suited for tanning.
