Abstract
Description
Von dem getrockneten Granulat wird durch Sieben der Grobkorn- und der Feinkornanteil abgetrennt. Der Grobkornanteil wird durch Vermahlen zerkleinert und ebenso wie der Feinkornanteil einem erneuten Granulierungsprozess zugeführt.
Der Gewichtsanteil an Ammoniumnitril bezogen auf das fertige, trockene Co-Granulat liegt bei 1 Gew-% bis 50 Gew-%, bevorzugt 10 Gew-% bis 40 Gew-%, besonders bevorzugt 15 Gew-% bis35 Gew-%.
Des weiteren eignen sich pulverförmige anionische Komponenten, insbesondere Alkansulfonate, Alkylarylsulfonate, Arylsulfonate, insbesondere Cumol-, Xylol-, Toluolsulfonat, Alkylethersulfate , Alkylsulfate, α-Olefinsulfonate und Seifen.
Die Menge an Bindemittel, bezogen auf das fertige Granulat, kann 1 bis 45 Gew.-%, vorzugsweise 5 bis 15 Gew.-% betragen.
Besonders geeignete Polymere sind Polyacrylsäure, Polymaleinsäure oder Copolymere aus Acrylsäure und Maleinsäure.
Dieser Schritt kann in üblichen, chargenweise oder kontinuierlich arbeitenden Mischvorrichtungen, die in der Regel mit rotierenden Mischorganen ausgerüstet sind, erfolgen, beispielsweise in einem Pflugscharmischer. Je nach Wirksamkeit der Mischvorrichtung liegen die Mischzeiten für ein homogenes Gemisch im allgemeinen zwischen 30 Sekunden und 5 Minuten.
Die Herstellung kann auch in der Weise erfolgen, daß alle Komponenten trocken vermischt und anschließend das Gemisch unter Wasserzugabe granuliert wird. In einer weiteren Variante kann ein Gemisch aus trockenen Komponenten mit einem oder mehreren wasserfeuchten Feststoff(en) vermengt und granuliert werden.
Ebenfalls geeignete Zusätze sind Komplexbildner und Übergangsmetallkomplexe, z.B. Eisen-, Cobalt- bzw. Mangan-haltige Metallkomplexe wie in EP-A-0 458 397 und EP-A-0 458 398 beschrieben.
Als Aminoxide kommen besonders C10-C18-Alkyldimethylaminoxide und C8-C12-Alkoxyethyl-Dihydroxyethylaminoxide in Frage.
Als anionische Tenside kommen in Betracht vor allem geradkettige und verzweigte Alkylsulfate, -sulfonate, -carboxylate, -phosphate, Alkylestersulfonate, Arylalkylsulfonate, Alkylethersulfate und Mischungen aus den genannten Verbindungen. Im folgenden sollen einige der in Frage kommenden Typen von anionischen Tensiden näher beschrieben werden.
Brauchbare organische Gerüstsubstanzen sind beispielsweise die bevorzugt in Form ihrer Natriumsalze eingesetzten Carbonsäuren, wie Citronensäure, Nitriloacetat (NTA) sowie Ethylendiamintetraessigsäure, sofern ein derartiger Einsatz aus ökologischen Gründen nicht zu beanstanden ist und Phosphon- und Polyphosphonsäuren . Analog hierzu können auch polymere Carboxylate und deren Salze eingesetzt werden. Hierzu gehören beispielsweise die Salze homopolymerer oder copolymerer Polyacrylate, Polymethacrylate und insbesondere Copolymere der Acrylsäure mit Maleinsäure, vorzugsweise solche aus 50 % bis 10 % Maleinsäure, sowie Polyasparaginsäure und auch Polyvinylpyrrolidon und Urethane. Die relative Molekülmasse der Homopolymeren liegt im allgemeinen zwischen 1000 und 100 000, die der Copolymeren zwischen 2000 und 200 000, vorzugsweise 50 000 bis 120 000, bezogen auf die freie Säure, insbesondere sind auch wasserlösliche Polyacrylate geeignet, die beispielsweise mit etwa 1 % eines Polyallylethers der Sucrose quervernetzt sind und die eine relative Molekülmasse oberhalb einer Million besitzen. Beispiele hierfür sind die unter dem Namen Carbopol 940 und 941 erhältlichen Polymere.
Die Enzyme können an Trägersubstanzen adsorbiert werden und/oder in Hüllsubstanzen eingebettet sein.
