Verfahren zur Herstellung von Amyloid.
Es ist bereits bekannt, Baumwollabfälle mit Schwefelsäure und Wasser zu behandeln, zu dem Zwecke, amyloidartige Körper zu erhalten. Das Verfahren hat sich in die Technik indes nicht einführen lassen, weil Baumwollabfälle einerseits zu teuer und schwer zu bekommen sind,

Das vorliegende Verfahren hat nun den Zweck, aus Holzabfällen. Sägespänen und anderen zellulosehältigen Stoffen Amyloid zu gewinnen. Dies geschieht in der Weise, dass man auf die

Vorteilhaft ist es, das Amyloid mit verdünnter kochender Schwefelsäure zu losen und wieder zu fäden bzw. so lange zu kochen, bis die Stärke verkleistert. Ein besonderes Augenmerk ist der Trocknung zuzuwenden, damit die Temperatur nicht zu hoch steigt.
Gegenüber der gewöhnlichen Behandlung von Holz mit Schwefelsäure erzielt man bei dem vorliegenden Verfahren eine Mehrausbeute von 20% und darüber. abgesehen von den geringen Apparaturanlagen, welche dabei in Verwendung kommen.
PATENT-ANSPRÜCHE :

Process for making amyloid.
It is already known to treat cotton waste with sulfuric acid and water for the purpose of obtaining amyloid-like bodies. However, the process could not be introduced into the technology because cotton waste is too expensive and difficult to get hold of,

The purpose of the present process is now to extract wood waste. Sawdust and other cellulosic materials to gain amyloid. This is done in such a way that one on the

EMI1.6
It is advantageous to loosen the amyloid with diluted boiling sulfuric acid and to thread it again or to boil it until the starch gelatinizes. Particular attention should be paid to drying so that the temperature does not rise too high.
Compared to the usual treatment of wood with sulfuric acid, the present process achieves an additional yield of 20% and more. apart from the small amount of equipment that is used.
PATENT CLAIMS:
1. Process for the production of amvloid from cellulosic materials, in particular wood flour. characterized in that the starting material is dissolved in a mixture of sulfuric acid and sodium sulfate or other sulfates, whereupon the amyloid in known
