Description

  

  Verfahren zur Herstellung eines neuen     Zellnlosederivates.       Es wurde gefunden, dass man ein neues       Zellulosederivat    erhält, wenn man auf Al  kalizellulose eine Verbindung der Formel-  
EMI0001.0003     
    einwirken lässt.  



  Das neue     Zellulosederivat    ist durch seine  basischen Eigenschaften ausgezeichnet und  hat Affinität zu den meisten sauren Farb  stoffen. Es ist in den üblichen Lösungs  mitteln für Zellulose löslich und lässt sich  daraus in beliebiger Form wiedergewinnen.  Das Produkt kann als Rohstoff zur Her  stellung von Textilfasern verwendet werden.  Indessen wird der Schutz für das angege  bene Verfahren nur soweit beansprucht, als  es sich nicht um eine für die Textilindu  strie in Betracht kommende Behandlung von  Textilfasern zum Zwecke von deren Ver  edlung handelt.  



       Beispiel   <I>1:</I>  16 Teile Zellulose (Zellstoff, Baumwolle,       Linters,    regenerierte Zellulose     etc.)    werden    in 160 Teile 18%ige Natronlauge eingelegt.  Nach 3     Stunden    zentrifugiert man die über  schüssige Lauge ab und ,geht mit der Zel  lulose in eine Lösung von 7 Teilen     Chlor-          äthyldiäthylamin    in Aceton. Man lässt unter  häufigem Durchrühren 3     Stunden    in der Lö  sung und wäscht hernach     mit    Wasser und  schliesslich mit verdünnter Essigsäure, wo  rauf man die Zellulose trocknet.

   Man erhält  eine hellgefärbte Masse, die mit sauren Farb  stoffen     färbbar    ist.  



  Das Verfahren lässt sich auch auf gelöste       Alkalizellulose    anwenden.     Dran    kann auch  das neue Erzeugnis in weitere Zellulose  derivate umwandeln -     zum    Beispiel durch       Xanthogenieren,        Acetylieren    usw. - und  hierauf weiter verarbeiten.  



  <I>Beispiel 2</I>  Man führt 15 Teile lose Baumwolle in  N     atronzellulose    über und fügt nach dem Ab  pressen 18 Teile     Chloräthyldiäthylaminchlor-          hydrat    zu. Durch das überschüssige Alkali  wird die organische Base in Freiheit gesetzt.      Man knetet 8 Stunden lang durch, worauf  man auswäscht. Das erhaltene neue     Zellu-          losederivat    kann als solches verwendet wer  den, oder zur Herstellung weiterer Zellulose  derivate.



  Process for the production of a new cellless derivative. It has been found that a new cellulose derivative is obtained if a compound of the formula
EMI0001.0003
    can act.



  The new cellulose derivative is characterized by its basic properties and has an affinity for most acidic dyes. It is soluble in the usual solvents for cellulose and can be recovered from it in any form. The product can be used as a raw material for the manufacture of textile fibers. In the meantime, protection for the specified process is only claimed insofar as it does not involve a treatment of textile fibers for the purpose of refining them that is suitable for the textile industry.



       Example <I> 1 </I> 16 parts of cellulose (cellulose, cotton, linters, regenerated cellulose, etc.) are placed in 160 parts of 18% sodium hydroxide solution. After 3 hours, the excess liquor is centrifuged off and the cellulose is dissolved in a solution of 7 parts of chloroethyl diethylamine in acetone. It is left in the solution for 3 hours with frequent stirring and then washed with water and finally with dilute acetic acid, whereupon the cellulose is dried.

   A light-colored mass is obtained which can be colored with acidic dyes.



  The process can also be applied to dissolved alkali cellulose. On it, the new product can also be converted into further cellulose derivatives - for example by xanthating, acetylating, etc. - and then processed further.



  <I> Example 2 </I> 15 parts of loose cotton are transferred into nitrocellulose and, after pressing, 18 parts of chloroethyl diethylamine chlorohydrate are added. The organic base is set free by the excess alkali. You knead for 8 hours, after which you wash out. The new cellulose derivative obtained can be used as such or for the production of further cellulose derivatives.
