Description

Verfahren zur Herstellung von wasserunlösliden, sticlçstoffhaltigen Kunstharzen Es wurde gefunden, daß wasserunlösliche Kunstharze, die sich hervorragend als Elektronenaustauscher eignen, hergestellt werden können, indem man ringgeschlossene Chinonfarbstoffe mit Aldehyden in Gegenwart von ein- oder mehrwertigen Phenolen umsetzt.Process for the production of water-insoluble, nitrogen-containing Synthetic Resins It has been found that water-insoluble synthetic resins are excellent Suitable as electron exchangers, can be produced by making ring-closed Quinone dyes with aldehydes in the presence of mono- or polyhydric phenols implements.

Ringgeschlossene Chinonfarbstoffe, die für die Herstellung der genannten Kunstharze verwendet werden können, sind beschrieben in Paul Karrer »Lehrbuch der organischen Chemie« (I95G) S. 671 bis 683. Es sind dies Phenazinfarbstoffe, wie z.B. Tolusafranin, Oxazinfarbstoffe (Capriblau und Gallaminblauj und insbesondere Thiazinfarbstoffe, so ie z. B. Methylenblau. Geeignete Aldehvde sind insbesondere Formaldehyd und Verbindungen, die wie Formaldehyd reagieren, wie z. B. Paraformaldehyd, ferner Furfurol und andere zur Herstellung von Kunstharzen verwendbare Aldehyde. Die Umsetzung der vorgenannten Komponenten wird vorz gsweise in wäßrigem Medium in Anwesenheit von Säuren oder Alkali als Katalysatoren, wie z. B. von Ätzalkalien oder Mineralsäuren, bei erhöhten Temperaturen vorgenommen. Ring-closed quinone dyes used for the manufacture of the aforesaid Synthetic resins that can be used are described in Paul Karrer's textbook organic chemistry "(195G) pp. 671 to 683. These are phenazine dyes, such as e.g. tolusafranine, oxazine dyes (capri blue and gallamine blue and especially Thiazine dyes, so ie z. B. Methylene Blue. Suitable aldehydes are in particular Formaldehyde and compounds that react like formaldehyde, e.g. B. paraformaldehyde, also furfural and other aldehydes which can be used for the production of synthetic resins. The aforementioned components are preferably reacted in an aqueous medium in the presence of acids or alkali as catalysts, such as. B. of caustic alkalis or mineral acids, made at elevated temperatures.

Es werden auf diese Weise wasserunlösliche Kunstharze erhalten, die sich hervorragend zur Durchführung von Oxydations- und Reduktionsprozessen eignen. Sie können z. B. zur Entfernung des Sauerstoffes aus Industriewässern eingesetzt werden und zeichnen sich hierbei durch eine besonders hohe Wirksamkeit aus. Ferner besitzen sie den Vorteil, daß sie in oxydierter Form tiefgefärbt sind, während sie in reduzierter Form farblos bzw. schwach gefärbt sind, so daß sich an diesen Harzen ohne weitere Hilfsmaßnahmen aus ihrer Farbe erkennen läßt, ob sie in oxydierter oder reduzierter Form vorliegen. Durch Behandlung mit geeigneten Reduktionsmitteln, wie z. B. mit Natriumhydrosulfit, lassen sich die oxydierten Harze in die reduzierte Form überführen, so daß diese erneut, gegebenenfalls nach vorhergegangenem Waschen, zur Durchführung von Reduktionsprozessen eingesetzt werden können. In this way, water-insoluble synthetic resins are obtained which are ideal for carrying out oxidation and reduction processes. You can e.g. B. used to remove oxygen from industrial waters are and are characterized by a particularly high level of effectiveness. Further Do you own the advantage that it is deeply colored in oxidized form are, while they are colorless or weakly colored in a reduced form, so that can be recognized by their color on these resins without further auxiliary measures, whether they are in oxidized or reduced form. By treating with suitable Reducing agents, such as. B. with sodium hydrosulfite, the oxidized Convert resins into the reduced form so that they can be used again, if necessary after previous washing, can be used to carry out reduction processes can.

Die Harze können ferner auch auf Trägermaterialien kondensiert werden. So ist es z. B. möglich, als Trägermaterial Papier zu verwenden. The resins can also be condensed onto carrier materials. So it is B. possible to use paper as a carrier material.

Werden diese Papiere anschließend reduziert, so lassen sie sich infolge ihrer Empfindlichkeit gegenüber oxydierenden Mitteln als Reagenzpapier zum Nachweis von Sauerstoff in gasförmigen oder flüssigen Medien verwenden.If these papers are subsequently reduced, they can be reduced as a result their sensitivity to oxidizing agents as reagent paper for detection use of oxygen in gaseous or liquid media.

Beispiel 220 g Resorcin und 2I,4g Methylenblau werden in 230 ccm Formaldehydlösung (30°/oig) gelöst und nach Zugabe von 4 ccm 1'/obiger NaOH-Lösung zum Sieden erhitzt. Die Flüssigkeit erstarrt nach kurzer Zeit zu einem Gel, welches zerkleinert - und gewaschen wird. Example 220 g of resorcinol and 2I, 4 g of methylene blue are in 230 ccm Formaldehyde solution (30%) dissolved and after addition of 4 ccm 1 '/ above NaOH solution heated to boiling. The liquid solidifies after a short time to form a gel, which shredded - and washed.

Ausbeute: 260 g. Yield: 260 g.

Zur Überführung in die reduzierte Form wird das Harz mit ammoniakalischer 5°/iger Hydrosulfitlösung behandelt, bis die Farbe des Harzes von tiefblauschwarz nach fast farblos umgeschlagen ist. To convert the resin into the reduced form, it is mixed with ammoniacal 5% hydrosulphite solution treated until the color of the resin is deep blue-black after it has turned almost colorless.

Das oben beschriebene Harz kann auch auf Papierstreifen kondensiert werden, indem die Kondensation der beschriebenen Komponenten zunächst nur so weit geführt wird, daß das Kondensationsprodukt in Alkohol noch löslich ist, worauf das Papier mit dieser alkoholischen Lösung getränkt und anschließend auf Temperaturen von I30 bis I700 erhitzt wird.The resin described above can also be condensed on strips of paper be by the condensation of the components described initially only so far is performed that the condensation product is still soluble in alcohol, whereupon that Paper soaked with this alcoholic solution and then heated to temperatures is heated from I30 to I700.
