Description
Verfahren zur Herstellung einer resorbierbaren Pudergrundlage Bei der Erfindung handelt es sich um ein Verfahren zur Herstellung einer resorbierbaren Pudergrundlage. Process for the production of an absorbable powder base Bei The invention relates to a method for producing an absorbable Powder base.
Das Verfahren besteht darin, daß Stärke mit wasserhaltigen, technischen Methylolverbindungen des Melamins, insbesondere Trimethylolmelamin, bei wenig erhöhter Temperatur gemischt und nach Trocknung einige Zeit auf höhere Temperatur erhitzt wird. Dabei wird vorzugsweise beim Mischen Wasser bis zur pastösen Konsistenz zugegeben.The process consists in that starch with hydrous, technical Methylol compounds of melamine, in particular trimethylol melamine, with little increased Mixed temperature and, after drying, heated to a higher temperature for some time will. When mixing, water is preferably added until it has a pasty consistency.
Durch das erfindungsgemäße Verfahren wird die Stärke in eine nicht quellende, wasserunlösliche Form übergeführt. Hierdurch wird die Möglichkeit geschaffen, die Stärke als Grundlage für pharmazeutische und kosmetische Puder zu verwenden. The inventive method, the starch in a not swelling, water-insoluble form. This creates the possibility to use the starch as a basis for pharmaceutical and cosmetic powders.
Es sind schon früher Verfahren zur Herstellung nicht quelifäbiger Stärke beschrieben worden. Diese Verfahren beruhten auf Behandlung der Stärke mit Formaldehyd. Dadurch wird aber ein Produkt erzielt, das durch Einwirkung von Feuchtigkeit nach einiger Zeit Formaldehyd abspaltet und seine Quellfähigkeit zurückerlangt. Später wurden Umsetzungen mit Epichlorhydrin beschrieben, die ebenfalls die Quellfähigkeit nur zum Teil verhinderten und außerdem unwirtschaftlich waren. Processes for the production are not more readily available even earlier Strength has been described. These procedures were based on treating the starch with Formaldehyde. In this way, however, a product is obtained that is exposed to moisture after some time formaldehyde is split off and its swellability is regained. Reactions with epichlorohydrin were later described, which also had the ability to swell were only partially prevented and also uneconomical.
Ein neueres Verfahren setzt hochmolekulare Naturstoffe (Kasein und Stärke) mit Methylolverbindung in wäßriger Suspension in Gegenwart sauer reagierender Mittel um. Dieses Verfahren ist umständlich, insofern das Wasser abgesaugt bzw. abgepreßt werden muß. A more recent process uses high-molecular natural substances (casein and Starch) with methylol compound in aqueous suspension in the presence of acidic reacting Funds around. This procedure is cumbersome if the water is sucked off or must be pressed.
Der apparative Aufwand ist wesentlich größer. Außerdem nehmen die zusätzlichen Arbeitsgänge eine verhältnismäßig lange Zeit in Anspruch, so daß das Verfahren im ganzen kostspielig ist.The outlay on equipment is much greater. They also take additional operations take a relatively long time, so that the Procedure on the whole is costly.
Die Erfindung beinhaltet eine Umsetzung von Stärke mit wasserhaltigen Methylolverbindungen des Melamins, wie sie als Zwischenprodukte in der Kunststoffindustrie anfallen, insbesondere Trimethylolmelamin, ohne daß die Stoffe in wäßrige Suspension gebracht werden und ohne daß sauer reagierende Mittel zugegen sein müssen. Nach dem Verfahren wird die Stärke mit der feuchten Methylolverbindung gut durchmischt. The invention includes a reaction of starch with hydrous Methylol compounds of melamine, such as those used as intermediates in the plastics industry accrue, in particular trimethylolmelamine, without the substances in aqueous suspension be brought and without acidic agents must be present. To In the process, the starch is mixed well with the moist methylol compound.
Der Mischungsvorgang findet mit Vorteil bei etwa 400 C statt. Anschließend wird bei nur wenig erhöhter Temperatur getrocknet und schließlich die trockene, feinpulverisierte Masse einige Zeit einer Temperatur von 125 bis 1350 C ausgesetzt. Das entstandene, nicht quellende Stärkeprodukt kann noch mit warmen Wasser ausgewaschen werden. Es ist besonders als indifferente, resorbierbare Pudergrundlage geeignet und kann überall dort eingesetzt werden, wo Talkum wegen seiner Granulombildungsgefahr und Stärke wegen ihrer Quellbarkeit keine Anwendung finden können. Insbesondere ist es als Grundlage für Wundstreupulver und zur Herstellung von Tamponaden ge- eignet, da es nicht nur resorbierbar, nicht quellend und gut wasseraufsaugend, sondern außerdem autosteril ist.The mixing process advantageously takes place at around 400 ° C. Afterward is dried at only a little higher temperature and finally the dry, finely powdered mass exposed to a temperature of 125 to 1350 C for some time. The resulting, non-swelling starch product can still be washed out with warm water will. It is particularly suitable as an indifferent, absorbable powder base and can be used wherever talc because of its risk of granuloma formation and starch cannot be used because of their swellability. In particular it is used as the basis for wound litter powder and for the production of tamponades. suitable, because it is not only absorbable, does not swell and absorbs water well, but also is auto sterile.
Beispiel 1 100. g Kartoffelstärke werden mit 40 g feuchtem Trimethylolmelamin (etwa 50 °/o Wassergehalt) gut verrieben. Bei Verreiben erhitzt man die Masse auf 40 bis 450 C Wenn eine gleichmäßige Verreibung erreicht ist, wird das Ganze bei etwa 450 C getrocknet. Example 1 100 g of potato starch are mixed with 40 g of moist trimethylol melamine (about 50% water content) rubbed well. When rubbing in, the mass is heated up 40 to 450 C When an even grinding is achieved, the whole thing will be at dried about 450 C.
Die vollkommen ausgetrocknete Masse wird fein pulverisiert und, in dünnen Schichten ausgebreitet, 1 Stunde lang auf 1350 C im Trockenschrank erhitzt.The completely dried out mass is finely pulverized and, in Spread out in thin layers, heated for 1 hour at 1350 C in a drying cabinet.
Nach dem Abkühlen wäscht man das Produkt mehrmals mit warmen Wasser, um Rückstände von Trimethylolmelamin zu entfernen, und pulverisiert nach Trocknung bei etwa 700 C nochmals fein. Das so erhaltene Produkt bildet eine autosterile, gleitfähige und gut absorbierende Pudergrundlage aus nicht quellender und unlöslicher Stärke.After cooling, the product is washed several times with warm water, to remove residues of trimethylol melamine, and pulverized after drying again fine at about 700 C. The product obtained in this way forms an autosterile, Slippery and well absorbing powder base made of non-swelling and insoluble Strength.
Beispiel 2 Wie im Beispiel 1 werden 40 g feuchtes Trimethylolmelamin mit 100 g Stärke verrieben und so viel Wasser zugesetzt, daß eine pastöse Masse entsteht. Example 2 As in Example 1, 40 g of moist trimethylolmelamine are obtained Triturated with 100 g of starch and added enough water to make a pasty mass arises.
Diese pastöse Masse wird kurze Zeit bei 40 bis 450 C durchgeknetet und dann wie im Beispiel 1 weiterverarbeitet. Die Gleitfähigkeit des Endproduktes ist etwas besser als bei dem des Verfahrens 1. In den übrigen Eigenschaften gleichen sich beide Produkte vollkommen.This pasty mass is kneaded for a short time at 40 to 450 C. and then further processed as in example 1. The lubricity of the end product is slightly better than that of method 1. In the other properties both products are completely identical.
