STOLLE & KOPKE in RUMBURG, Böhmen. Verfahren zur Herstellung löslicher Stärke.STOLLE & KOPKE in RUMBURG, Bohemia. Process for making soluble starch.
Zusatz zum Patente 199753 vom 8. Juli 1906.Addendum to patent 199753 of July 8, 1906.
Patentiert im Deutschen Reiche vom 6. Januar 1907 ab. Längste Dauer: 7.JuIi 1921.Patented in the German Empire on January 6, 1907. Longest duration: July 7, 1921.
Durch das Patent 199753 ist ein Verfahren unter Schutz gestellt, bei dem Stärke durch Einwirkung von Perboraten in die lösliche Form übergeführt wird, und zwar entweder dadurch, daß die Stärke trocken mit Perborat gemischt wird und beim Auflösen zum Gebrauch in die lösliche Modifikation übergeht, oder die Stärke mit einer Perboratlösung bzw. mit dem Perborat bei Gegenwart von Wasser erwärmt und eventuell wieder von der wäßrigen Flüssigkeit getrennt wird.A process is protected by the patent 199753, in which starch by The action of perborates is converted into the soluble form, either in that the starch is dry mixed with perborate and when dissolved for use changes into the soluble modification, or the starch with a perborate solution or heated with the perborate in the presence of water and possibly again from the aqueous Liquid is separated.
Die vorliegende Erfindung besteht nun in der Erkenntnis, daß die Reaktion auch dann vor sich geht, wenn lediglich das hygroskopische Wasser bei der Wechselwirkung zwischen Perborat und Stärke zugegen ist, una daß es des Zusatzes weiterer Wassermengen nicht bedarf.The present invention now consists in the recognition that the reaction even going on when only the hygroscopic water is present in the interaction between perborate and starch, una that it does not require the addition of further quantities of water.
Das Verfahren wird derart ausgeführt, daß die Handelsstärke mit Perboratgemischen beispielsweise auf 100° erhitzt wird. Die Stärke ist dann in die lösliche Modifikation übergegangen. The method is carried out so that the commercial starch with perborate mixtures, for example is heated to 100 °. The starch has then passed into the soluble modification.
