Description

Verfahren zum Plastischmachen von Cellulosederivaten. Es wurde :gefunden, daß idiie durch Konden- sation von Acetaldehyd: bzw. Paraldehyd mit Phenolen erhältlichen Äthylidendiphenole (i.i) in hervorragendem Maße igeeignet sind, an Stelle von K ampher verwandt zu werdien. Besonders als Mittel zum Elastisch- bzw. Plastischmachen von Cellulosederivaten er- setzen diese Körper Aden Kampher in vorzüg- licher Weise .und liefern vollkommen .klage und elastische Gelluloidmassen. Dliie Äthy- lidendiphenole sind leicht löslich: in Alkohol, Aceton und Äther. B,eispiel. 25 Teile Äthyli@dendiplienol (i.i) (Annalen, 363. Bd.. S1 255) werden mit ioo Teilen Nitro- cellulose vermlischt und in einem ider üblichen Lösuivgsmittel, z. B, einer Mischung von, Al- kohol mit Aceton, zur Aufquedlunig ,gebracht. Man erhält nach Aufarbeitung einen klaren, elasbschlen Film. Vor idiem, in: der britischen Patentschrift 188--9--, vom Jahre ig i2 ,genannten Dioxydi- phenyldimethylmet'han zieichnet sich das Dioxydiphenyl'äthan durch ganz besonders gesteigerte Lösungsfähigkeit sowohl für Nitrocellu.losie als auch: für Ac-etylzellulos-e .au's. Process for plasticizing cellulose derivatives. It has been found that by condensation sation of acetaldehyde: or paraldehyde with Ethylidenediphenols available from phenols (ii) are eminently suitable, to be related in place of K ampher. Especially as a means of elastic or Plasticizing cellulose derivatives put these bodies aden camphor in preferential lure way .and deliver completely .might and elastic geluloid masses. Dliie Ethy- lidendiphenols are easily soluble: in alcohol, Acetone and ether. Example. 25 parts of Äthyli @ dendiplienol (ii) (annals, 363. Vol. S1 255) are with 100 parts nitro- cellulose mixed and in an ider usual Solvents, e.g. B, a mixture of, Al- alcohol with acetone, brought to quenching. After working up, a clear, elasible film. Before idiem, in: the British patent specification 188--9--, from year i2, called dioxydi- phenyldimethylmet'han that draws itself Dioxydiphenyl'äthan by very special increased solvency for both Nitrocellu.losie as well as: for Ac-etylzellulos-e .the end.
