Österreichische PATENTSCHRIFT Nu 19604. DR. LEONHARD LEDERER IN SULZBACH (OBERPFALZ).
Verfahren zur Herstellung hornartiger Produkte.
Bei der weiteren Bearbeitung des dem Patente Nr. 16377 zugrunde liegenden Verfahrens wurde gefunden, dass mit Hilfe von ein-oder mehrwertigen Phenolen oder im Kern substituierten Derivaten derselben und geeigneten Lösungsmitteln Lösungen von
EMI1.1
mittels hornartige Produkte ergeben, die sich in dünnen Schichten besonders gut für die Verwendung als Films eignen. Als vorzügliches Lösungsmittel erwies sich Azeton, das wegen seiner leichten Verdunstbarkoit und wegen seiner Eigenschaft, mit anderen Flüssigkeiten sich zu mischen, besondere Vorteile bietet. Um durchscheinende, undurchsichtige oder gefärbte hornartige Körper herzustellen, werden den Lösungen unlösliche Verbindungen, wie Metalloxyde. Metallsultnh'u. dgl. zugesetzt. Wendet man zu diesem Zwecke z. B.
Bleioxyd an, so erhält man ein Produkt von elfenbeinähnlichem Aussehen.
EMI1.2
schriebenen Verfahren insofern Vorteile, als dadurch auch solche Phenole, welche erst oberhalb der Zersetzungstemperatur der Azetylzellulose schmelzen, für das Verfahren nutzbar gemacht werden können.
Das Verfahren mag an folgendem Beispiel Erläuterung finden, ohne auf dasselbe beschränkt zu sein : 1 Teil Azetylzellulose wird in 4 Teilen Phenol gelöst und alsdann mit 25 Teilen Azeton sorgfältig gemischt. Wird diese Mischung auf eine Glasplatte gegossen und verdunsten gelassen, so hinterbleibt ein glasklarer Film.

Austrian PATENT LETTER No. 19604. DR. LEONHARD LEDERER IN SULZBACH (OBERPFALZ).
Process for the production of horn-like products.
In the further processing of the process on which patent no. 16377 is based, it was found that with the aid of monohydric or polyhydric phenols or derivatives thereof substituted in the nucleus and suitable solvents, solutions of
EMI1.1
by means of horn-like products, which are particularly suitable in thin layers for use as films. Acetone proved to be an excellent solvent, which offers particular advantages because of its easy evaporability and its ability to mix with other liquids. In order to produce translucent, opaque or colored horn-like bodies, insoluble compounds, such as metal oxides, are added to the solutions. Metal sultnh'u. Like. Added. If you apply for this purpose z. B.
Lead oxide, a product with an ivory-like appearance is obtained.
EMI1.2
The described processes have advantages in that they can also make use of phenols which only melt above the decomposition temperature of acetyl cellulose for the process.
The process may be illustrated by the following example, without being restricted to the same: 1 part acetyl cellulose is dissolved in 4 parts phenol and then carefully mixed with 25 parts acetone. If this mixture is poured onto a glass plate and allowed to evaporate, a crystal-clear film remains.
