Description
<Desc/Clms Page number 1>
Verfahren zur Herstellung von Amyloid.
Aus der Stamm-Patentschrift Nr. 33969 geht hervor, dass die Behandlung der Cellulose mit Schwefelsäure bezw. mit Sulfatlösungen namentlich Natriumsulfat zum Zwecke der
EMI1.1
handlung der Cellulose mit Bisulfaten und namentlich Natriumbisulfat aitein der Prozess in gleicher Weise vor sich geht und dass die Regelung der Reaktion noch leicht. er möglich ist als wie nach dem in der Stamm-Patentschrift beschriebenen Verfahren. Vorteilhaft ist bs, dem Natriumbisnlfat, welches gleichfalls gr@sse Mengen von Schwefelsäure durch Schmelzen von Natriumbisulfat in konzentrierter Schwefelsäure aufzunehmen imstande ist, letztere zu inkorporieren.
Das so erhaltene Natriumbisulfat ist vollkommen wasserbell durch sichtig und geht durch Wasseraufnahme in ein opakes Produkt über unter stetiger Ab- gabe von Schwefelsäure. Die Verwendung von Natriumbisulfat kann in derselben Weise mit Schwefelsäure geschehen, wie in der Stamm-Patentschrift Nr. 33969 die Verwendung von Natriumsulfaton mit Schwefelsäure beschrieben ist.

Process for making amyloid.
The parent patent No. 33969 shows that the treatment of cellulose with sulfuric acid BEZW. with sulfate solutions, namely sodium sulfate for the purpose of
EMI1.1
Treatment of cellulose with bisulphates and especially sodium bisulphate aitein the process proceeds in the same way and that the regulation of the reaction is still easy. it is possible as according to the method described in the parent patent. It is advantageous to incorporate the sodium bisulfate, which is also able to absorb large amounts of sulfuric acid by melting sodium bisulfate in concentrated sulfuric acid.
The sodium bisulphate obtained in this way is completely transparent to water and turns into an opaque product when water is absorbed, with the constant release of sulfuric acid. The use of sodium bisulfate can be done with sulfuric acid in the same manner as the use of sodium sulfate with sulfuric acid is described in parent patent specification No. 33969.
