Es wurde die überraschende Beobachtung gemacht, daß man in einfacher Weise zu alkoholischen Lösungen von Acetylcellulosen dadurch gelangen kann, daß man letztere bei Gegenwart von Chlorzink oder Rhodansalzen, wie Rhodanammonium, Rhodankalium, in Alkoholen auflöst.The surprising observation was made that one can easily alcoholic solutions of acetyl celluloses can be obtained by using the latter at Presence of zinc chloride or rhodan salts, such as rhodanammonium, rhodanic potassium, in alcohols dissolves.
Derartige Lösungen, die auch bei Zimmertemperatur flüssig bleiben, besitzen vor denSuch solutions, which also remain liquid at room temperature, have before the
ίο bisher bekannten technische Vorteile. Sie lassen mannigfache Verwendung zu; denn einerseits können sie infolge der relativ (wenigstens im Vergleich zu Aceton, 'Essigäther, Chloroform) geringen Flüchtigkeit des Lösungsmittels mit dem Pinsel verstrichen werden, * so wie gewöhnliche Lacke, sodann erteilen sie der daraus erhältlichen Schicht keinerlei anhaftenden Geruch. Die Rhodansalze und das Chlorzink, welche in der Schicht hygroskopisch wirken, lassen sich mit Wasser leicht auswaschen; die Lösung eignet sich vorzüglich zum Verspinnen, und kann hierbei Wasser als Fällbad benutzt werden, aus welchem nachträglich der Alkohol und die Salze leicht wieder gewonnen werden können.ίο previously known technical advantages. she allow multiple uses; because on the one hand, as a result of the relative (at least low volatility of the solvent compared to acetone, vinegar ether, chloroform) are spread with a brush, * like ordinary lacquers, then they give the layer obtainable therefrom does not have any adhering odor. The rhodan salts and that Chlorine zinc, which has a hygroscopic effect in the layer, can be easily washed out with water; the solution is particularly suitable for spinning, and water can be used as a precipitation bath, from which subsequently the alcohol and salts can be easily recovered.
Je nach der beabsichtigten Verwendung können den Lösungen auch Zusätze, wie Kampfer oder dessen Ersatzprodukte, sowie Farben, Pigmente, Bronzen, Füllmassen usw.Depending on the intended use, the solutions can also contain additives such as Camphor or its substitute products, as well as paints, pigments, bronzes, fillers, etc.
oder auch Flüssigkeiten, die an und für sich die Acetylcellulosen nicht lösen, beigemischt werden.or liquids which in and of themselves do not dissolve the acetyl celluloses, mixed in will.
Das Chlorzink und die Rhodansalze üben auch bei Verwendung solcher Acetylcellulosen, die in Alkoholen allein bereits löslich sind, eine günstige Wirkung aus, insofern als sie verhindern, daß die in der Wärme hergestellten Lösungen beim Erkalten gelatinieren.The zinc chloride and the rhodan salts also exercise when using such acetylcelluloses, which are already soluble in alcohols alone have a beneficial effect insofar as they prevent the solutions produced in the heat from gelatinizing on cooling.

ioo Teile acetonlösliche Acetylcellulose werden zusammen mit 300 Teilen wasserfreiem Chlorzink und 600 Teilen Äthylalkohol zur Lösung gebracht.100 parts of acetone-soluble acetyl cellulose are combined with 300 parts of anhydrous Zinc chloride and 600 parts of ethyl alcohol brought to solution.
Man erhält so eine vollkommen klare Lösung.A completely clear solution is obtained in this way.
100 Teile acetonlösliche Acetylcellulose werden zusammen mit 300 Teilen wasserfreiem Chlorzink, 600 Teilen Äthylalkohol zur Lösung gebracht und 500 Teile Benzol, 25 Teile Kampfer und dann 50 Teile Goldbronze zugesetzt. 100 parts of acetone-soluble acetyl cellulose are combined with 300 parts of anhydrous Zinc chloride, 600 parts of ethyl alcohol and 500 parts of benzene, 25 parts Camphor and then 50 parts of gold bronze were added.
Man erhält so eine Lösung, die sich zum Bronzieren von Gegenständen der verschiedensten Art sehr gut eignet.One thus obtains a solution which can be used for bronzing objects of the most varied Kind of very suitable.
100 Teile acetonlösliche Acetylcellulose werden in einer Lösung von 300 Teilen Chlorzink in 600 Teilen Methylalkohol gelöst, dann 200 Teile Tetrachlorkohlenstoff zugegeben und gut verrührt.100 parts of acetone-soluble acetyl cellulose are in a solution of 300 parts of zinc chloride Dissolved in 600 parts of methyl alcohol, then 200 parts of carbon tetrachloride were added and well mixed.
50 Teile chloroformlösliche Acetylcellulose werden zusammen mit 600 Teilen Chlorzink in 600 Teilen Methylalkohol gelöst.50 parts of chloroform-soluble acetyl cellulose are used together with 600 parts of zinc chloride dissolved in 600 parts of methyl alcohol.
