Description

  

  Verfahren zur Herstellung eines neuen     Cellulosederivates.       Es wurde gefunden, dass man ein neues       Cellulosederivat    erhält, wenn man auf     Cellu-          lose        Triphenylmethoxyphosphordichlorid    in  Gegenwart von tertiären Basen einwirken  lässt.  



  Das neue     Cellulosederivat    bildet ein helles  Produkt und ist gegenüber     Direktfarbstoffen     unempfänglich, lässt sich dagegen mit ba  sischen     Farbstoffen    färben. Es kann als       Rohstoff    zur Herstellung von Textilfasern  verwendet werden. Indessen wird der Schutz  für das angegebene Verfahren nur so weit  beansprucht, als es sich nicht um eine für  die Textilindustrie in Betracht kommende  Behandlung für Textilfasern zum Zwecke  deren Veredlung handelt.  



  <I>Beispiel:</I>  10 Teile     Cellulose    in Form von     Linters,     loser Baumwolle,     Sulfitcellulose        etc.    werden  in einer Lösung von 5-10 Teilen Triphenyl-         methoxyphosphordichlorid    in 200-300 Teilen  trockenem     Pyridin    während 8-20 Stunden  auf dem siedenden Wasserbade behandelt  und nachher gründlich gespült.



  Process for the production of a new cellulose derivative. It has been found that a new cellulose derivative is obtained if triphenylmethoxyphosphorus dichloride is allowed to act on cellulose in the presence of tertiary bases.



  The new cellulose derivative forms a light-colored product and is insensitive to direct dyes, but can be dyed with basic dyes. It can be used as a raw material for making textile fibers. However, protection for the specified process is only claimed insofar as it does not involve a treatment for textile fibers for the purpose of their finishing that is suitable for the textile industry.



  <I> Example: </I> 10 parts of cellulose in the form of linters, loose cotton, sulfite cellulose etc. are boiled in a solution of 5-10 parts of triphenyl methoxyphosphorus dichloride in 200-300 parts of dry pyridine for 8-20 hours Treated with water bath and rinsed thoroughly afterwards.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Cellulosederivates, dadurch gekennzeichnet, dass Cellulose in Gegenwart von tertiären Basen mit Triphenylmethoxyphosphordichlorid behandelt wird. Das neue Cellulosederivat bildet ein helles Produkt und ist gegenüber Direktfarbstoffen unempfänglich, lässt sich dagegen mit ba sischen Farbstoffen färben. Es kann als Rohstoff zur Herstellung von Textilfasern behandelt werden. PATENT CLAIM: Process for the production of a new cellulose derivative, characterized in that cellulose is treated with triphenylmethoxyphosphorus dichloride in the presence of tertiary bases. The new cellulose derivative forms a light-colored product and is insensitive to direct dyes, but can be colored with basic dyes. It can be treated as a raw material for making textile fibers.
