Es ist bekannt, daß Carbonsäuregruppen tragende Kunstharzgele als Kationenaustauscher Verwendung finden.It is known that synthetic resin gels carrying carboxylic acid groups are used as cation exchangers Find.

Es wurde nun gefunden, daß man überraschenderweise derartige Produkte in besonders einfacher und vorteilhafter Weise herstellen kann, wenn man Phenolaldehydharze vorzugsweise in Form von Gallerten bei erhöhter Temperatur mit Kohlensäure und bzw. oder Kohlensäure abgebenden Stoffen, z. B. Bicarbonaten, behandelt. Je nach Art des Ausgangsmaterials, der Temperatur, des Drucks und der Behandlungszeit treten dabei wechselnde Mengen von Carbonsäuregruppen in das Harzmolekül ein, so daß man auf diese Weise Austauschermaterialien mit ausreichender Kapazität leicht gewinnen kann. Die Harzgrundkörper können auf der Grundlage von ein- oder mehrwertigen Phenolen hergestellt sein, d. h. sie können an sich kationenaktiver oder inaktiver Natur sein. Auch geeignete Substitutionsprodukte der phenolischen Ausgangsmaterialien können bei der Herstellung des Grundkörpers verwendet werden. Die zu behandelnden Harzgrundkörper werden den gewählten Reaktionsbedingungen entsprechend angewendet, d. h. es ist gegebenenfalls zweckmäßig, sie mit Alkali zu beladen. It has now been found that, surprisingly, such products can be obtained in a particularly simple manner and can advantageously be prepared if phenol aldehyde resins are preferably used in the form of Jellied at elevated temperature with carbonic acid and / or substances emitting carbonic acid, z. B. bicarbonates treated. Depending on the type of starting material, the temperature, the pressure and During the treatment time, varying amounts of carboxylic acid groups enter the resin molecule so that exchange materials with sufficient capacity can easily be obtained in this way can. The resin base can be based on monohydric or polyhydric phenols be manufactured, d. H. they can be cation-active or inactive in nature. Also suitable Substitution products of the phenolic starting materials can be used in the manufacture of the base body be used. The resin base bodies to be treated are used in accordance with the selected reaction conditions, d. H. it is it may be useful to load them with alkali.

Beispielexample

Eine Lösung aus 440 Teilen Resorcin und 10 Teilen Ätznatron in 400 Teilen Wasser wird bei 200 CA solution of 440 parts of resorcinol and 10 parts of caustic soda in 400 parts of water at 20 0 C

unter Kühlung mit 520 Teilen 3ö°/oigem Formalin in der Weise versetzt, daß man eine Reaktionstemperatur von ioo° C erreicht. Nach 2stündigem Stehen der so erhaltenen Harzgallerte wird das Produkt auf eine Korngröße von etwa 0,5 bis 2 cm 0 zerkleinert und mit 2000 Teilen Wasser, 440 Teilen Natriumbicarbonat und 500 Teilen Kohlensäure im Autoklav während 5 Stunden erhitzt. Hält man bei dieser Arbeitsweise die Temperatur auf no0 C, so erhält man ein kationenaustauschendes Harz, welches als Wasserstoffionenaustauscher eine Volumenleistung von 0,24'1Vo Ca O aufweist. Steigert man die Temperatur auf 1300 C, so weist das erhaltene Produkt eine Kapazität von o,30fl/oCaO auf, während man bei 1500C ein Material mit einer Volumenkapazität von r,o8°/o CaO erhält.520 parts of 30% formalin are added while cooling in such a way that a reaction temperature of 100 ° C. is reached. After the resin jelly thus obtained has stood for 2 hours, the product is comminuted to a particle size of about 0.5 to 2 cm and heated with 2000 parts of water, 440 parts of sodium bicarbonate and 500 parts of carbonic acid in an autoclave for 5 hours. If the temperature is kept at 0 ° C. in this procedure, a cation-exchanging resin is obtained which, as a hydrogen ion exchanger, has a volume performance of 0.24% 1 % by volume of CaO. The temperature is increased to 130 0 C, so the obtained product has a capacity of o, 30 fl / oCaO, while a material is obtained with a volume capacity of r, o8 ° / o CaO at 150 0 C.
