Verfahren zum Lösen und Gelatinieren von Zelluloseestem.
Die Zahl der brauchbaren Lösungs-und Gelatinierungsmittel für Zelluloseester ist gering, zumal wenn man ein derartiges Universalmittel für alle Zelluloseester sucht. Es ist besonders ein geeignetes Lösungsmittel, welches jede Art acetylierter Zellulose löst bzw.
EMI1.1
Es wurde nun die überraschende Beobachtung gemacht, dass das jetzt als Abfallprodukt in grossen Mengen gewonnene und verwendungslose Furfurol bzw. seine Homologen alle Arten von Zelluloseestern, wie z. B. Nitrozellulose und Acetylzellulose jedweder Acetylierungsart und-stufe sowie gemischte Zelluloseester, wie z. B.
Nitro-Acetylzellulose, löst und gelatiniert,
Das Furfurol bzw. seine Homologen werden in der bekannten Art zu Lösungen, Lacken und plastischen Massen verarbeitet. Überraschenderweise wurde hierbei ferner festgestellt, dass bereits ein verhältnismässig geringer Prozentsatz Furfurol genügt, um eine
Gelatinierung der Zelluloseester herbeizuführen, ähnlich der, welche Kampfer in der Nitrozellulose bei der Zelluloidfabrikation ausübt. Zur Ausführung des Verfahrens kann sowohl reines, wie technisches Furfurol oder seine Homologen allein oder im Gemisch mit anderen, die Zelluloseester lösenden bzw. nicht lösenden Gemischen verwendet werden.
Es ist selbstverständlich, dass den Stoffen auch weich machende Zusätze sowie solche, die irgendeine besondere Wirkung an dem Produkt ausüben sollen, zugefügt werden können. Das Verfahren sei kurz an einigen Beispielen erläutert.
Bei s pie I 1. 10 Teile acetonlösliche Acetylzellulose werden mit i Teil Furfurol und Z0 Teilen Alkohol im Knetapparat geknetet und auf plastische Massen verarbeitet.
Beispiele 11. 10 Teile tetrachloraethanlösliche Acetylzellulose werden in 50 Teilen Furfurol gelöst. Der Lösung können Benzol oder Alkohol und auch Wasser als Streckungsmittel zugefügt werden.
Beispiel ni. 10 Teile Nitrozellulose werden mit i Teil Furfurol und 10 Teilen Alkohol geknetet und auf plastische Massen verarbeitet. Es ist selbstverständlich, dass an Stelle des Furfurols auch seine Homologen, z. B. Methylfurfurol (z. B. in der gleichen Menge wie in den obigen Beispielen angegeben), genommen und dass an Stelle von Alkohol auch andere Flüssigkeiten gewählt werden können. Es ist weiter selbstverständlich, dass jeder dieser Zelluloseester sowohl zu Lacken und Lösungen, wie auch zu plastischen Massen mit Furfurol bzw. seinen Homologen verarbeitet werden kann. Die Beispiele sollen nur die Vielseitigkeit des Verfahrens beweisen.

Process for dissolving and gelatinizing cellulose esters.
The number of usable solvents and gelatinizing agents for cellulose esters is small, especially if one is looking for such a universal agent for all cellulose esters. It is a particularly suitable solvent that dissolves or dissolves any type of acetylated cellulose.
EMI1.1
The surprising observation has now been made that the useless furfural or its homologues now obtained as a waste product in large quantities and all types of cellulose esters, such as. B. nitrocellulose and acetyl cellulose of any acetylation type and stage and mixed cellulose esters, such as. B.
Nitro acetyl cellulose, dissolves and gelatinizes,
The furfural or its homologues are processed in the known way to solutions, lacquers and plastic materials. Surprisingly, it was also found here that a relatively low percentage of furfural is sufficient to produce a
To bring about gelatinization of the cellulose esters, similar to that which camphor exerts in the nitrocellulose in the celluloid production. To carry out the process, both pure and technical furfural or its homologues can be used alone or in a mixture with other mixtures which dissolve or do not dissolve the cellulose esters.
It goes without saying that softening additives as well as those that are intended to exert any special effect on the product can also be added to the fabrics. The process will be explained briefly using a few examples.
At pie I 1. 10 parts of acetone-soluble acetyl cellulose are kneaded with 1 part of furfural and 10 parts of alcohol in a kneader and processed into plastic masses.
Examples 11. 10 parts of tetrachloroethane-soluble acetyl cellulose are dissolved in 50 parts of furfural. Benzene or alcohol and also water can be added to the solution as an extender.
Example ni. 10 parts of nitrocellulose are kneaded with 1 part of furfural and 10 parts of alcohol and processed into plastic masses. It goes without saying that instead of furfural, its homologues, e.g. B. methylfurfurol (z. B. in the same amount as specified in the above examples), and that other liquids can be selected instead of alcohol. It is also a matter of course that each of these cellulose esters can be processed into lacquers and solutions as well as into plastic compositions with furfural or its homologues. The examples are only intended to demonstrate the versatility of the process.
