Description

  

  Verfahren zur Herstellung eines neuen blauen Farbstoffes der     Anthrachinonreihe.       Im schweizerischen Patent Nr. 232608 ist  ein Verfahren     zur'    Herstellung von blauen  Farbstoffen der     Anthrachinonreihe    beschrie  ben, welches darin besteht, dass man in     6-          bezw.        7-Stellung        halogenierte        Chinizarine    mit       Aminoalkoholen    der allgemeinen Formel         R-CH-(NH,)-R10H,       worin R     Alkyl    und     R,        Alkylen        bedeuten,

       kondensiert und durch Behandlung     mit,Sul-          fierungsmitteln    in die     entsprechenden        Schwe-          felsäureester    überführt.  



  Es wurde nun gefunden, dass man zu glei  chen Farbstoffen gelangt, wenn man     Schwe-          felsäureester    der     Aminoalkohole    der obenge  nannten Formel als Ausgangsprodukte be  nutzt.  



  Das vorliegende Patent betrifft ein     Ver     fahren zur Herstellung des     Dischwefelsäure-          esters    des     1.4-Di-(butanol-1'-amino-2'-)-6-          chloranthrachinons,    welches dadurch gekenn  zeichnet ist, dass man 1     Mol        Leuko-6-chlor-          chinizarin    mit 2     Mol    des     Schwefelsäureesters       des     2-Aminobutanol-1    kondensiert und die       Leukoverbindung    oxydiert.  



  Der so erhaltene Farbstoff löst sich in  Wasser mit blauer Farbe und färbt     Wolle     und andere Textilien in lebhaften blauen Tö  nen an.  



  <I>Beispiel:</I>  12 Teile     Leuko-6-chlorchinizarin,    18 Teile  des     Natriumsalzes    des     2-Aminobutanol-l-          schwefelsäureesters,    80 Teile Alkohol und  12 Teile Wasser werden bei 50-80  gerührt,  bis die Kondensation beendet ist. Nach Oxy  dation mit Luft, eventuell bei Gegenwart von       Piperidin,        Pyridin    oder     Dimethylanilin    und  etwas Kupferacetat, wird der Farbstoff durch  Filtration und Waschen mit Alkohol isoliert  und gegebenenfalls durch Kristallisation ge  reinigt. Er färbt Wolle und andere Textilien  in lebhaften blauen Tönen an.



  Process for the production of a new blue dye of the anthraquinone series. In Swiss patent no. 232608 a process for the 'production of blue dyes of the anthraquinone series is described ben, which consists in that one in 6- respectively. 7-position halogenated quinizarines with amino alcohols of the general formula R-CH- (NH,) - R10H, where R is alkyl and R, is alkylene,

       condensed and converted into the corresponding sulfuric acid esters by treatment with sulphurizing agents.



  It has now been found that the same dyes are obtained if sulfuric acid esters of the amino alcohols of the above formula are used as starting materials.



  The present patent relates to a process for the preparation of the disulfuric acid ester of 1,4-di- (butanol-1'-amino-2 '-) - 6-chloroanthraquinone, which is characterized in that 1 mole of leuco-6-chlorine is used - Quinizarin condensed with 2 moles of the sulfuric acid ester of 2-aminobutanol-1 and oxidized the leuco compound.



  The dye thus obtained dissolves in water with a blue color and stains wool and other textiles in vivid blue tones.



  <I> Example: </I> 12 parts of leuco-6-chloroquinizarin, 18 parts of the sodium salt of 2-aminobutanol-1-sulfuric acid ester, 80 parts of alcohol and 12 parts of water are stirred at 50-80 until the condensation has ended. After oxidation with air, possibly in the presence of piperidine, pyridine or dimethylaniline and a little copper acetate, the dye is isolated by filtration and washing with alcohol and optionally purified by crystallization. He dyes wool and other textiles in vivid blue tones.
