Das vorliegende Verfahren betrifft die Herstellung elastischer Massen aus Nitrocellulose oder Acetylcellulose und den Kondensationsprodukten aus Formaldehyd und harz- oder fettsauren primären aromatischen Basen und einer Lösung von Leim, Kasein oder Albumin.. Beispielsweise kann man das harzsaure oder fettsaure Salz des aromatischen Amins mit der Nitro- oder Acetylcellulose verarbeitenThe present process relates to the production of elastic compositions from nitrocellulose or acetyl cellulose and the condensation products of formaldehyde and resinous or fatty acid primary aromatic bases and a solution of glue, casein or albumin .. For example, you can use the resin acid or Process the fatty acid salt of the aromatic amine with the nitro or acetyl cellulose
ίο und dann Formaldehyd einwirken lassen, oder aber man kann Nitro- oder Acetylcellulose in den harz- oder fettsauren Salzen der aromatischen Basen zuerst lösen, diese Lösung mit einer solchen aus Leim, Kasein oder Albumin oder Gemengen dieser Stoffe in Wasser, Glycerin, Phenol usw. emulgieren und auf diese Emulsion Formaldehyd einwirken lassen. In letzterem Falle wirkt das Formaldehyd zunächst auf die Salzlösung des Amins so ein, daß eine Anhydroformaldehydverbindung entsteht und weiterhin unlöslicher Formaldehydleim und Albumin oder Kasein gebildet wird. Es scheint aber hierbei eine tiefergreifende Veränderung in der Richtung stattzufinden, daß durch die Vereinigung der Anhydroformaldehydamin-Celluloseesterlösung mit der Formaldyd-Leim-. usw. Verbindung ein einheitlicher Körper vielleicht nach Art eines Celluloids entstanden ist.ίο and then let formaldehyde take effect, or but one can use nitro or acetyl cellulose in the resinous or fatty acid salts of the aromatic ones First dissolve bases, this solution with one made of glue, casein or albumin or mixtures of these substances in water, glycerine, phenol etc. and emulsify on them Let the formaldehyde emulsion take effect. In the latter case, the formaldehyde acts first on the salt solution of the amine in such a way that an anhydroformaldehyde compound is formed and insoluble formaldehyde glue and albumin or casein continue to be formed. But here there seems to be a more profound change in the direction that by combining the anhydroformaldehyde amine cellulose ester solution with the formaldehyde glue. etc. Connection of a unitary body, perhaps in the manner of a celluloid originated.
i. 125 g gepulverter Leim und 25 g frischgefälltes Kasein werden in der Wärme in 150 g Glycerin von 310 Be. gelöst. 80 g Nitro- oder Acetylcellulose werden unter Zusatz von Ätheralkohol und Essigäthei» in 30 g Colophonium und 15 g Anilin gelöst, dann mit 5 g etwa iooprozentigem Formaldehyd auf dem Wasserbad so lange erwärmt, bis jede Reaktion vorüber ist und die flüchtigen Substanzen entfernt sind. Man kann auch an Stelle des Colophoniums Ölsäure oder Stearinsäure in gleicher Menge verwenden, doch hat sich Harz am zweckmäßigsten erwiesen. Beide Lösungen werden emulgiert. Die erhaltene Emulsion wird bei etwa 60 bis 700 mit 10 g 40 prozentiger Formaldehydlösung zwecks Überführung des verwendeten Leims bzw. Kaseins in Formaldehyd-Leim oder -Kasein längere Zeit innig verrührt.i. 125 g of powdered glue and 25 g of freshly precipitated casein are heated in 150 g of glycerine of 31 0 Be. solved. 80 g of nitro or acetyl cellulose are dissolved in 30 g of rosin and 15 g of aniline with the addition of ether alcohol and acetic acid, then heated with 5 g of about 10% formaldehyde on a water bath until every reaction is over and the volatile substances have been removed. It is also possible to use oleic acid or stearic acid in the same amount instead of rosin, but resin has proven to be the most expedient. Both solutions are emulsified. The resulting emulsion is vigorously stirred at about 60 percent to 70 0 with 10 g of formaldehyde solution 40 in order to transfer the glue or casein used in formaldehyde glue or casein longer time.
2. 150 g Leimpulver, in 100 g Glycerin von 310Be. und 50 g entrahmter Milch gelöst, werden mit 50 g der nach Beispiel 1 erhaltenen Mischung aus Anhydroformaldehydbase und den Celluloseestern in Aceton gelöst, emulgiert und die erhaltene Emulsion bei etwa 60 bis 700 mit 10 g einer 40 prozentigen Formaldehydlösung zwecks Überführung des verwendeten Leims bzw. Kaseins der Milch in Formaldehyd-Leim oder -Kasein innig verrührt. 2. 150 g glue powder, in 100 g glycerine of 31 0 Be. and 50 g of skimmed milk dissolved, are dissolved with 50 g of the mixture of anhydroformaldehyde base and the cellulose esters obtained in Example 1 in acetone, emulsified and the emulsion obtained at about 60 to 70 0 with 10 g of a 40 percent formaldehyde solution for the purpose of transferring the glue used or Casein of milk intimately mixed in formaldehyde glue or casein.
In der britischen Patentschrift 22525/1905 . ist die Herstellung plastischer Massen aus , Kasein und Formaldehyd unter Verwendung von Anilin u. dgl. beschrieben worden. Die verwendeten Basen sollen den Zweck haben, ein Aufquellen des Kaseins zu bewirken. Hierbei können ebenfalls Anhydro formaldehydverbindungen der verwendeten Basen entstehen. Anydroformaldehydverbindungen der primären aromatischen Amine liefern nur bildsame Massen, während die Anhydroform-In British Patent Specification 22525/1905. is the production of plastic masses from, Casein and formaldehyde using aniline and the like have been described. the The bases used should have the purpose of causing the casein to swell. Here Anhydro formaldehyde compounds of the bases used can also be formed. Anydroformaldehyde compounds of the primary aromatic amines only yield plastic ones Masses, while the anhydroform

aldehydverbindungen der öl-, fett- oder harzsauren primären aromatischen Amine elastische Massen liefern. Bei Verwendung der primären aromatischen Amine tritt auch in Mischung mit Kolloiden die Bildung kristallinischer Stoffe auf, wodurch eine Entmischung der Massen veranlaßt wird. Bei den Anhydroformaldehydverbindungen der harz-, öl- oder fettsauren primären aromatischen Amine wird ίο dagegen dieser Übelstand vermieden.aldehyde compounds of oleic, fatty or resin acids primary aromatic amines provide elastic masses. When using the primary Aromatic amines also occur when mixed with colloids to form crystalline forms Substances, whereby a segregation of the masses is caused. With the anhydroformaldehyde compounds The resin, oleic or fatty acid primary aromatic amines, on the other hand, avoid this problem.
