Description

Celluloseestermassen Die Erfindung betrifft die Herstellung von Celluloseestermassen und besonders Massen, die Celluloseacetat enthalten.Cellulose ester masses The invention relates to the production of cellulose ester masses and especially compositions containing cellulose acetate.

Man hat bereits vorgeschlagen, als Plastifizierungsmittel in solchen Massen gemischte Arylester der Phosphorsäure zu verwenden.It has already been proposed as a plasticizer in such Use bulk mixed aryl esters of phosphoric acid.

Gemäß der Erfindung wird ein Gemisch von Diphenylmonokresylphosphat und Monophenyldikresylphosphat, und zwar in einem Mischungsverhältnis von io bis ii Gewichtsteilen Diphenylmonokresylphosphat und 6 bis 7 Gewichtsteilen Monophenyldikresylphosphat verwendet. Zweckmäßig werden gemäß der Erfindung die angegebenenStoffe inGemeinschaft mit denhöher gechlorten Derivaten von Äthan und anderen Kohlenwasserstoffen der Paraffinreihe verwendet.According to the invention, a mixture of diphenyl monocresyl phosphate and monophenyl dicresyl phosphate, in a mixing ratio of 10 to ii parts by weight of diphenyl monocresyl phosphate and 6 to 7 parts by weight of monophenyl dicresyl phosphate used. According to the invention, the specified substances are expedient in community with the higher chlorinated derivatives of ethane and other hydrocarbons of the Paraffin series used.

Die so erzeugten Massen können bei der Herstellung von dünnen Folien, kinematographischen Filmen, künstlichen Fasern und für andere Zwecke benutzt werden, für die man plastifizierte Celluloseestermassen anwendet.The masses produced in this way can be used in the production of thin foils, cinematographic films, man-made fibers and other purposes, for which plasticized cellulose ester masses are used.

Die folgenden Einzelheiten werden als Ausführungsbeispiele angegeben, um geeignete Methoden zur Ausführung der Erfindung zu erläutern.

Die aus der Erfindung hergeleiteten Vorteile sind kurz wie folgt: Durch die Benutzung von gemischten Phosphorsäureestern wird eine Verminderung der Entflammbarkeit des Produktes erzielt, ohne daß die Massen den Nachteil des Auskristallisierens zeigen, wie dies der Triphenylester von Phosphorsäure aufweist. Gleichzeitig entspricht die Dehnbarkeit, die den Produkten erteilt wird, einer solchen, die man durch den Gebrauch von Trikresylphosphat-erhält, aber ohne den Nachteil, der dem Trikresylester infolge der Fettigkeit oder Schmierigkeit des Films anhaftet. Weiterhin geben gemischte Phosphorsäureester gemäß der Erfindung Produkte, die ein besseres Aussehen haben als ähnliche Produkte, die man mit Hilfe von Triphenyl- oder Trikresylphosphat herstellt, da diese gemischten Phosphorsäureester einen außergewöhnlichen hohen Siedepunkt und niedrigen Dampfdruck haben und daher nicht die Neigung besitzen, aus dem Film zu sublimieren, wie Triphenylphosphat das tut. Wenn die gemischten Phosphorsäureester in Gemeinschaft mit Heptachlorpropan benutzt werden, so wird die Festigkeit des erzeugten Fabrikats erheblich gesteigert.The following details are given as exemplary embodiments to illustrate suitable methods for carrying out the invention. Example i Thin film: Cellulose acetate. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100 parts by weight Diphenyl monocresyl phosphate ......... - ......... 22 » Monophenyl dicresyl phosphate ................... 1g » Chlorine derivatives of paraffinic hydrocarbons .... i-3 » Usual solvents ..................... in a suitable amount Cinematographic Films: Cellulose acetate. ... . . . . . . . . . . . . . . . . . . . . . . . . ... . 100 parts by weight Diphenyl monocresyl phosphate ...: .............. 20 » Monophenyl dicresyl phosphate ................... 12 » Chlorine derivatives of paraffinic hydrocarbons .... 3-i0 » suitable solvents ..... ...... .... ...... in suitable quantities Artificial silk: Cellulose acetate. . . . . . . . . . . . . . . . . . . . . . . . . . . . 100 parts by weight Diphenyl monocresyl phosphate .. .. .. ..... .. ...... 23 » Monophenyl dicresyl phosphate ................... 1q. » Chlorine derivatives of paraffinic hydrocarbons. . 5-i2 » suitable solvents .. .... .... . ... .. .. ... in a suitable amount Example 2 Nitrocellulose. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100 parts by weight Diphenyl monocresyl phosphate ........... ........ 27 » Monophenyl dicresyl phosphate ......... ....... 18 » Chlorinated hydrocarbons ................... 6 » The production of foils, films or fibers according to the invention corresponds to the usual methods which are used in the production of similar objects from known cellulose ester masses. The advantages derived from the invention are briefly as follows: By using mixed phosphoric acid esters, a reduction in the flammability of the product is achieved without the compositions showing the disadvantage of crystallization, as the triphenyl ester of phosphoric acid has. At the same time, the extensibility imparted to the products corresponds to that obtained through the use of tricresyl phosphate, but without the disadvantage attached to the tricresyl ester due to the greasiness or greasiness of the film. Furthermore, mixed phosphoric acid esters according to the invention give products that have a better appearance than similar products that are produced with the aid of triphenyl or tricresyl phosphate, since these mixed phosphoric acid esters have an exceptionally high boiling point and low vapor pressure and therefore do not have the tendency from which Sublime film like triphenyl phosphate does. If the mixed phosphoric acid esters are used in conjunction with heptachloropropane, the strength of the manufactured product is considerably increased.
