Description

  

  Verfahren zur Herstellung eines neuen     Zellulosederivates.       Es     wurde    gefunden, dass man ein neues       Zellulosederivat    erhält, wenn man auf Al  kalizellulose in Gegenwart von säurebinden  den Mitteln eine Verbindung der Formel  
EMI0001.0004     
    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 Lösungsmit  teln für Zellulose löslich und lässt sich dar  aus in beliebiger Form wiedergewinnen. Das  neue Produkt kann als Rohstoff zur Herstel  lung von Textilfasern verwendet werden. In  dessen wird der Schutz für das angegebene  Verfahren nur soweit beansprucht, als es sich  nicht um eine für die Textilindustrie in Be  tracht kommende Behandlung von Textil  fasern zum Zwecke deren Veredlung handelt.

      <I>Beispiel:</I>  Man imprägniert 15 Teile Zellstoff mit  25%iger Natronlauge, presst nach     5-stündi-          gem    Liegen ab und übergiesst mit einer Lö  sung von 15 Teilen     Chloräthylpiperidin    in  Aceton. Man rührt während 5 Stunden bei  40 bis 60   und wäscht nachher mit Wasser.  Es werden 17 Teile des neuen     Zellulosederi-          vates    erhalten.



  Process for the production of a new cellulose derivative. It has been found that a new cellulose derivative is obtained if a compound of the formula is used on alkali cellulose in the presence of acid-binding agents
EMI0001.0004
    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 new product can be used as a raw material for the manufacture of textile fibers. In this, the protection for the specified process is only claimed insofar as it is not a treatment of textile fibers for the purpose of their finishing that is suitable for the textile industry.

      <I> Example: </I> 15 parts of cellulose are impregnated with 25% sodium hydroxide solution, pressed after lying for 5 hours and a solution of 15 parts of chloroethylpiperidine in acetone is poured over them. The mixture is stirred for 5 hours at 40 to 60 and then washed with water. 17 parts of the new cellulose derivative are obtained.

PATENT CLAIM: Process for the production of a new cellulose derivative, characterized in that a compound of the formula is applied to alkali cellulose in the presence of acid binding agents EMI0001.0013 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 new product can be used as a raw material for the manufacture of textile fibers. Indessen wird der Schutz für das angegebene Verfahren nur soweit beansprucht, als es sich nicht um eine für die Textilindustrie in Be tracht kommende Behandlung von Textil fasern behandelt. However, protection for the specified process is only claimed insofar as it does not deal with a treatment of textile fibers that is suitable for the textile industry.
