Description

  

  Verfahren zur Herstellung von mit sauren     Farbstoffen        färbbarer        Cellulose.       Es wurde gefunden, dass man eine mit  sauren Farbstoffen     färbbare        Cellulose    erhält,  wenn man     Cellulose    mit einer Lösung des  Additionsproduktes von     Trimethylamin    an       Chloracetami        nomethyl    -     trimethyl    -     ammonium-          chlorid    behandelt und     das    behandelte Mate  rial darauf erhitzt.  



  Es ist zweckmässig, der Lösung des     Tri-          methylaminadditionsproduktes    ein     Alkalisalz     einer schwachen Säure, z. B.     Natriumacetat     zuzufügen, und die Lösung schwach anzu  säuern, z. B. mit Ameisensäure.  



  Die so behandelte     Cellulose,    ein festes,  farbloses Material, hat basische Eigenschaften    und lässt sich mit sauren Farbstoffen, wie  sauren     Wollfarbstoffen,    in tiefen, echten  Tönen färben.  



  Für das angegebene Verfahren wird der  Schutz 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>       Cellulose        wird        in        einer        wässerigen        10%-          igen    Lösung des Additionsproduktes von       Trimethylamin    an     Chloracetamino-metbyl-          trimethyl-ammoniumchlorid    der Formel  
EMI0001.0030     
    unter Zusatz von     Natriumacetat    und soviel  Ameisensäure,

   dass die Lösung blaues Lack  muspapier rötet, bei 30-400 während 15-30  Minuten umgezogen, abgequetscht, zuerst    bei 50-60 0 getrocknet und dann während  vier Stunden auf     110-115'    erhitzt.  



  Die so erhaltene und leicht gespülte     Cel-          lulose,    ein festes, farbloses Material, hat      basische Eigenschaften und lässt sich mit  sauren     Farbstoffen,    wie sauren     Wollfarb-          stoffen,    in tiefen, echter) Tönen färben.  



  Das angewandte     quaternäre    Ammonium  salz kann wie folgt erhalten werden  12,3 Gewichtsteile     Methylolchloracetarnid     werden in 50     Volumteilen    Alkohol gelöst,  zu 30     Volumteilen    einer     benzolischen    Lösung  von     Trimethylamin    von 22     Vol.-Prozent     gegeben und über Nacht bei     gewöhnliel)er     Temperatur stehen gelassen.

   Hierauf gibt  man 9,5 Gewichtsteile     Trimethylaminchlor-          hydrat    hinzu und kocht während einer Stunde  unter     Rückflusskühlung.    Nach dem     Abdestil-          lieren    des Alkohols und Benzols     hinterbleibt     die neue     quaternäre        Ammoniumverbindung     als farblose,     zerfliessliche    Masse, die sich in  Wasser sehr leicht löst.



  Process for the production of cellulose which can be dyed with acidic dyes. It has been found that cellulose which can be dyed with acidic dyes is obtained if cellulose is treated with a solution of the addition product of trimethylamine to chloroacetamethyl-trimethyl-ammonium chloride and the treated material is heated on it.



  It is advisable to add an alkali salt of a weak acid, eg. B. add sodium acetate, and weakly acidify the solution, z. B. with formic acid.



  The cellulose treated in this way, a solid, colorless material, has basic properties and can be dyed in deep, genuine tones with acidic dyes, such as acidic wool dyes.



  For the specified process, protection is only claimed insofar as it is not a question of a treatment of textile fibers for the purpose of their finishing that is suitable for the textile industry. <I> Example: </I> Cellulose is in an aqueous 10% solution of the addition product of trimethylamine with chloroacetamino-methyl-trimethyl-ammonium chloride of the formula
EMI0001.0030
    with the addition of sodium acetate and so much formic acid,

   that the solution reddened blue lacquer paper, removed at 30-400 for 15-30 minutes, squeezed, first dried at 50-60 0 and then heated to 110-115 'for four hours.



  The easily rinsed cellulose obtained in this way, a solid, colorless material, has basic properties and can be dyed in deep, genuine shades with acidic dyes, such as acidic wool dyes.



  The quaternary ammonium salt used can be obtained as follows: 12.3 parts by weight of methylol chloroacetarnide are dissolved in 50 parts by volume of alcohol, added to 30 parts by volume of a benzene solution of trimethylamine of 22 percent by volume and left to stand overnight at the usual temperature.

   9.5 parts by weight of trimethylamine chlorohydrate are then added and the mixture is refluxed for one hour. After the alcohol and benzene have been distilled off, the new quaternary ammonium compound remains as a colorless, deliquescent mass that dissolves very easily in water.
