Beschreibungdescription
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von pulverformigen Wasserstoffperoxid-Komplexen auf Basis unlös¬ licher Polymerisate aus heterocyclischen N-Vmylmonomeren.The present invention relates to a process for the production of powdery hydrogen peroxide complexes based unlös ¬ Licher polymers of heterocyclic N-Vmylmonomeren.
Es ist allgemein bekannt, daß sich Wasserstoffperoxid bei län¬ gerer Lagerung zersetzt. Daher wurde eine-Vielzahl von Stabili satoren wie beispielsweise Polyvinylpyrrolidon eingesetzt, welche den Zersetzungsprozeß verhindern oder verlangsamen sollen.It is generally known that hydrogen peroxide decomposes on prolonged storage. Therefore, a variety of stabilizers such as polyvinylpyrrolidone were used to prevent or slow down the decomposition process.
Nach der US-A 5 008 093 lassen sich wasserfreie pulverformigeAccording to US Pat. No. 5,008,093, water-free powder can be used
Wasserstoffperoxid-Polyvinylpyrrolidon-Komplexe herstellen, indem Wasserstoffperoxid zu einer Suspension des PVP in einem wasser freien organischen Lösungsmittel gegeben und der sich bildende Komplex abfiltriert wird.Prepare hydrogen peroxide-polyvinylpyrrolidone complexes by adding hydrogen peroxide to a suspension of the PVP in a water-free organic solvent and filtering off the complex that forms.
Die Herstellung von Wasserstoffperoxid-PVP-Komplexen in wasser freiem organischen Lösungsmittel wird auch m der US-A 5 008 106 beschrieben.The preparation of hydrogen peroxide-PVP complexes in anhydrous organic solvents is also described in US Pat. No. 5,008,106.
Nachteilig an diesen Verfahren ist jedoch, daß zum einen wasser freie Losungsmittel benotigt werden, zum anderen mit hoch¬ konzentrierten Wasserstoffperoxid-Losungen gearbeitet werden muß. Außerdem kann nicht ausgeschlossen werden, daß die verwendeten organischen Lösungsmittel im Produkt verbleiben.A disadvantage of these processes, however, is that, on the one hand, water-free solvents are required and, on the other hand, highly concentrated hydrogen peroxide solutions have to be used. In addition, it cannot be excluded that the organic solvents used remain in the product.
In der US-A 5 190 749 wird die Herstellung von pulverformigen Komplexen aus Wasserstoffperoxid und PVP aus wäßrigen Losungen in einem Wirbelbettprozeß mit nachgeschalteter Trocknung beschrie¬ ben. Fur den Wirbelbettprozeß müssen Pulver bestimmter Korn- großenverteilungen eingesetzt werden. Die Wasserstoffperoxid zugäbe muß genau dosiert werden, da sonst gummiartige, klebrige Produkte entstehen.US Pat. No. 5,190,749 describes the production of powdery complexes of hydrogen peroxide and PVP from aqueous solutions in a fluidized bed process with subsequent drying. Powders of certain particle size distributions must be used for the fluidized bed process. The hydrogen peroxide addition must be dosed precisely, otherwise rubbery, sticky products are formed.
In der US A 3 376 110 ist die Herstellung von mit wasserun löslichen Polymerisaten auf Basis heterocyclischer N-Vmyllactame beschrieben, wobei eine wäßrige Aufsehlammung von Polymerisat und Wasserstoffperoxid durch Abdampfen des Wassers beispielsweise m einem Trockenofen m den festen Zustand überfuhrt wird. Nach teilig ist πedoch, daß bei vollständiger Trocknung gummiartige amorphe Zusammensetzungen entstehen. Aufgabe der vorliegenden Erfindung war es, em vereinfachtes Verfahren zur Herstellung von pulverformigen Wasserstoffperoxid Polymer-Komplexen zu finden, welches freifließende Produkte liefert.US Pat. No. 3,376,110 describes the preparation of polymers with water-insoluble polymers based on heterocyclic N-methyllactams, an aqueous suspension of polymer and hydrogen peroxide being evaporated from the water, for example in a drying oven, to the solid state. Partially, however, is that rubber-like amorphous compositions are formed when completely dried. The object of the present invention was to find a simplified process for the production of powdered hydrogen peroxide polymer complexes which provides free-flowing products.
Demgemäß wurde ein Verfahren zur Herstellung von pulverformigen Wasserstoffperoxid-Komplexen auf Basis unlöslicher Polymerisate von heterocyclischen N Vinylmonomeren gefunden, welches dadurch gekennzeichnet ist, daß man eine wäßrige Wasserstoffperoxidlosung mit der Polymerkomponente vermischt und den gebildeten Komplex abfiltriert.Accordingly, a process for the preparation of powdery hydrogen peroxide complexes based on insoluble polymers of heterocyclic N vinyl monomers has been found, which is characterized in that an aqueous hydrogen peroxide solution is mixed with the polymer component and the complex formed is filtered off.
Als Polymerkomponente kommen erfindungsgemaß unlösliche Poly meπsate von heterocyclischen N-Vinylmonomeren in Betracht, vor allem Homo- oder Copolymerisate von N-Vmylpyrrolidon, N-Vinyl- caprolactam oder N Vmylimidazol. Die Polymerisate können bis zu 80 Gew. -% an weiterer Comonomeren enthalten, beispielsweise Vinylester wie Vinylacetat, Vinylpropionat oder Vmylbutyrat oder Acrylsaure, Methacrylsaure oder die Ci-Ci Alkylester dieser Sauren. Die Polymerisate können physikalisch oder chemisch ver netzt sein. Als Vernetzer kommen beispielsweise cyclische Amide, die neben einer N Vmylgruppe eine weitere Vmylgruppe tragen, in Betracht, beispielsweise N,N' -Divmyl-ethylenharnstoff, N,N' Divmylpropylenharnstoff , N,N' -Divmylimidazolidon (2) , N Vmyl-2-ethyliden-pyrrolidon- (2) oder N Vmyl-3 -ethyliden-pipe ndmon- (2) in Betracht. Unlöslich bedeutet in diesem Zusammen hang, daß die Polymerisate weder in Wasser noch in üblichen orga nischen Lösungsmitteln loslich sind, bei einem Anteil an lösli¬ chen Anteilen von < 2 Gew.-%. Bevorzugte Polymerkomponente ist erfindungsgemaß unlösliches Polyvinylpyrrolidon (PVP) .According to the invention, polymer components which are insoluble are heterocyclic N-vinyl monomers, in particular homopolymers or copolymers of N-vinylmyrrolidone, N-vinylcaprolactam or Nvmylimidazole. The polymers can contain up to 80% by weight of further comonomers, for example vinyl esters such as vinyl acetate, vinyl propionate or vinyl butyrate or acrylic acid, methacrylic acid or the Ci-Ci alkyl esters of these acids. The polymers can be crosslinked physically or chemically. Suitable crosslinkers are, for example, cyclic amides which, in addition to an N Vmyl group, carry a further Vmyl group, for example N, N '-divmylethylene urea, N, N' divmylpropyleneurea, N, N '-divmylimidazolidone (2), N Vmyl-2 -ethylidene-pyrrolidone- (2) or N Vmyl-3-ethylidene-pipe ndmon- (2). Insoluble in this context means that the polymers are not soluble in water or in conventional organic solvents, with a proportion of soluble proportions of <2% by weight.

Die Art der Vermischung von Wasserstoffperoxid und Polymer- komponente ist nicht kritisch. Man kann die Polymerkomponente m fester Form oder als wäßrige Aufschlammung mit der Wasserstoff- peroxidlosung vermischen.The way in which hydrogen peroxide and polymer components are mixed is not critical. The polymer component can be mixed in solid form or as an aqueous slurry with the hydrogen peroxide solution.
Die Vermischung kann vorteilhafterweise unter Ruhren erfolgen. Die Bildung des Komplexes kann bei Temperaturen im Bereich von 0 bis 50°C, vorzugsweise 5 bis 25°C durchgeführt werden.

The formation of the complex can be carried out at temperatures in the range from 0 to 50 ° C., preferably 5 to 25 ° C. The duration of the reaction usually depends on the size of the batch and the desired hydrogen peroxide concentration in the Complex and can be easily determined by a person skilled in the art by means of a few simple experiments.
Die Mengenverhältnisse werden vorzugsweise so gewählt, daß die Umsetzung in Gegenwart von 1 bis 40, vorzugsweise 10 bisThe proportions are preferably chosen so that the reaction in the presence of 1 to 40, preferably 10 to

Die oberflächenaktiven Substanzen verbleiben nach der Isolierung in dem pulverformigen Komplex und erhohen die Wirkung des Wasser Stoffperoxids .After isolation, the surface-active substances remain in the powdery complex and increase the effect of the water peroxide.
Der gebildete Komplex wird anschließend durch Filtration von Wasser befreit, wobei die Filtration mit Hilfe von üblichen Filtern, beispielsweise Emschichtenprozeßflltern oder Kammerfil- terpressen erfolgen kann. Der Filterkuchen kann mit Luft trocken- gesaugt werden.The complex formed is then freed from water by filtration, it being possible for the filtration to be carried out with the aid of conventional filters, for example multi-layer process filters or chamber filter presses. The filter cake can be sucked dry with air.
