Description

Verfahren zur Herstellung von Trockenprodukten von Alkalistärke. Durch das Patent 389748 ist ein Verfahren geschützt, Trockenprodukte von Alkalistärke durch Beimischung von bei gewöhnlicher Temperatur hydrolytisch spaltbaren Alkaliverbindungen zur Stärke auf einfache und billige Weise herzustellen. Bei der Weiterverfolgung dieses Verfahrens wurde die überraschende Beobachtung gemacht, daß das Bariumhydroxyd besonders geeignet ist, die Alkaliverbindungen zu ersetzen. Bariumhydroxyd besitzt die außerordentlich wertvolle Eigenschaft, die angeschl;ämmte Stärke bei gewöhnlicher Temperatur nur in geringem Maße zur Verquellung zu bringen; erst beim Trocknen des Gemisches findet der Aufschluß, wahrscheinlich unter Bildung von Bäriumamylaten, statt. Dadurch gestaltet sich der Trockenvorgang besonders einfach und billig, und es werden Produkte von außerordentlich wertvollen technischen Eigenschaften: erhalten.Process for the preparation of dry products from alkali starch. By the patent 389748 is a protected process, dry products of alkali starch by adding alkali compounds which can be hydrolytically cleaved at ordinary temperature to produce starch in a simple and cheap way. In the follow-up In this procedure the surprising observation was made that the barium hydroxide is particularly suitable to replace the alkali compounds. Possesses barium hydroxide the extraordinarily valuable property, the connected strength in the ordinary To swell the temperature only to a small extent; only when the The digestion takes place in a mixture, probably with the formation of bearium amylates, instead of. This makes the drying process particularly simple and cheap, and products with extremely valuable technical properties are obtained.

Ausführungsbeispiele. i. ioo kg Kartoffelstärke werden mit 6 kg Bariumhydroxyd trocken gemischt und mit 75 bis ioo kg Wasser angeschlämmt. Die Masse wird in üblicher Weise getrocknet. Statt dessen kann auch so verfahren werden, daß man von einer Naßstärke ausgeht und dieser das Bariumhydroxyd in dem -angegebenen Mengenverhältnis zusetzt.Embodiments. i. 100 kg of potato starch are mixed with 6 kg of barium hydroxide mixed dry and slurried with 75 to 100 kg of water. The crowd becomes more common Way dried. Instead of this, the procedure can also be that one of a Wet starch runs out and this the barium hydroxide in the specified ratio clogs.

a. i oo kg Kartoffelstärke werden mit ioo kg Wasser angeschlämmt und mit 25 kg 5oprozentiger Harzseife und 5 kg Bariumhydroxyd gemischt. Die pastenartige bis leichtflüssige Masse wird getrocknet und das Trockengut erforderlichenfalls noch gemahlen.a. 100 kg of potato starch are slurried with 100 kg of water and mixed with 25 kg of 5% resin soap and 5 kg of barium hydroxide. The paste-like to slightly liquid mass is dried and the material to be dried is ground if necessary.
