Description
Verfahren zur Herstellung eines neuen Zellulosederivates. Es wurde gefunden, dass man ein neues Zellulosederivat erhält, wenn man auf Cyanurchlorid Alkalizellulose und Anilin einwirken lässt.
Das so erhaltene Produkt ist gegenüber direktziehenden güpen- und Säurefarbstof fen immun, es lässt sich dagegen mit basi schen Farbstoffen färben. Durch Kochen mit Wasser werden die färberischen Eigenschaf ten des neuen Produktes nicht geändert. Das selbe kann als Rohstoff zur Herstellung von Textilfasern und andern Erzeugnissen ver wendet werden. Indessen wird der Schutz für das angegebene Verfahren nur soweit be ansprucht, als es sich nicht um eine für die Textilindustrie in Betracht kommende Be handlung von Textilfasern zum Zwecke deren Veredlung handelt.
<I>Beispiel 1:</I> 10 Teile Cyanurchlorid werden in Aceton gelöst und hierauf in ein Gemisch von Eis, Wasser und 10 Teilen Anilin gegeben. Nach kurzem Rühren wird das pulverförmige Re aktionsprodukt abgenutscht, mit Wasser ge waschen und getrocknet.
Man löst es hierauf in 200 bis 300 Teilen Xylol und gibt zu die ser Lösung Alkalizellulose, welche ihrerseits aus 10 Teilen Zellulose entweder durch Be handeln mit 10 % iger alkoholischer Kalilauge oder mit 18%iger wässeriger Kalilauge oder mit einem Gemisch von 1 Teil 33 % iger Natronlauge, 1 Teil Alkohol und 1/2 Teil Wasser hergestellt worden ist. Man erhitzt 2 Stunden auf 60 bis 80 , spült und trocknet.
<I>Beispiel 2:</I> 10 Teile Linters werden in 18%iger Na tronlauge imprägniert, abgepresst und iii einer Lösung von 5 bis 10 Teilen Cyanur- chlorid in 200 Teilen Tetrachlorkohlenstoff bei 25 bis<B>30'</B> eingetragen; die Temperatur steigt ziemlich rasch auf 60 bis 65 . Nach 2 Stunden werden 20 Teile Anilin zugegeben; man überlässt diese Lösung sich selbst wäh rend 24 Stunden. Hierauf wird filtriert und das verbleibende Produkt nacheinander mit Alkohol und Wasser gewaschen und dann getrocknet.
Process for the production of a new cellulose derivative. It has been found that a new cellulose derivative is obtained if alkali cellulose and aniline are allowed to act on cyanuric chloride.
The product obtained in this way is immune to substantive high-quality and acidic dyes, but it can be colored with basic dyes. Boiling with water does not change the coloring properties of the new product. The same can be used as a raw material for the manufacture of textile fibers and other products. However, protection for the specified process is only claimed to the extent that it does not involve a treatment of textile fibers for the purpose of refining them which is suitable for the textile industry.
Example 1: 10 parts of cyanuric chloride are dissolved in acetone and then added to a mixture of ice, water and 10 parts of aniline. After brief stirring, the powdery reaction product is suction filtered, washed ge with water and dried.
It is then dissolved in 200 to 300 parts of xylene and alkali cellulose is added to this solution, which in turn consists of 10 parts of cellulose either by being treated with 10% alcoholic potassium hydroxide solution or with 18% aqueous potassium hydroxide solution or with a mixture of 1 part 33% iger caustic soda, 1 part alcohol and 1/2 part water has been made. The mixture is heated to 60 to 80 for 2 hours, rinsed and dried.
<I> Example 2: </I> 10 parts of linters are impregnated in 18% sodium hydroxide solution, pressed off and a solution of 5 to 10 parts of cyanuric chloride in 200 parts of carbon tetrachloride at 25 to 30% > registered; the temperature rises fairly quickly to 60 to 65. After 2 hours, 20 parts of aniline are added; you leave this solution to itself for 24 hours. It is then filtered and the product that remains is washed successively with alcohol and water and then dried.
