Description

Verfahren zur Herstellung geschmeidiger hassen aus Zelluloseestern. Es wurde gefunden, daß die Ester der durch Einwirkung von Sulfosäurechloriden in alkalischer Lösung auf i-Nitroso-2-naphthol nach Patent 411955 erhältlichen o-Zyanzimtsäure vom Schmelzpunkt i37-' sich vorzüglich zur Weichhaltung von Massen und Gebilden aus Zelluloseestern eignen. Die Ester sind aus der Säure bequem nach den üblichen Methoden darstellbar. Ihre Verarbeitung geschieht in der auch sonst bei der Herstellung von Filmen und Kunstleder üblichen Weise.Process for making pliable hate from cellulose esters. It has been found that the esters of the by the action of sulfonic acid chlorides in alkaline solution based on i-nitroso-2-naphthol according to patent 411955 o-cyancinnamic acid available from the melting point of 37- 'is excellent for keeping masses and structures soft made of cellulose esters are suitable. The esters are conveniently made from the acid according to the usual Methods representable. Your processing takes place in the otherwise in the production of films and leatherette usual way.

Die Verwendung von Estern der Zimtsäure zum gleichen Zweck ist bekannt, die Ester der o-Zyanzimtsäure haben gegenüber diesen außer ihrer technisch bequemeren und billigeren Herstellungsweise den Vorteil stärleerer Wirkung. Um z. B. einer Masse aus Nitrozellulose einen Weichheitsgrad zu verleihen, für den ioo Teile Zimtsäureamylester erforderlich wären, genügen etwa 66 Teile des o-Zyanzimtsäureesters. Auch ist die Kältebeständigkeit der so zusammengesetzten Massen eine bessere.The use of esters of cinnamic acid for the same purpose is known the esters of o-cyancinnamic acid have, in addition to theirs, technically more convenient compared to these and cheaper production methods have the advantage of a stronger effect. To z. B. one To give the mass of nitrocellulose a degree of softness, for the ioo parts of amyl cinnamate would be required, about 66 parts of the o-cyancinnamate are sufficient. Also is that The cold resistance of the masses composed in this way is better.
