Description

  

  Verfahren zur Herstellung eines     Küpenfarbstoffes.       Es wurde gefunden,     dass    ein wertvoller       Küpenfarbstoff    hergestellt werden kann, wenn  man     1-Amino-4-(p-sullodimethylamido-ben-          voylamino)-7-,chlor-anthrachinon    mit einem  funktionellen Derivat der     Chinolin-6-earbon-          säure    umsetzt.  



  Der neue Farbstoff löst sich in     konz.     Schwefelsäure mit roter Farbe und färbt  Baumwolle aus blaugrüner     Küpe    in echten       Rosatönen.     



  Als funktionelles Derivat der genannten       Carbonsäure    kann mit Vorteil ein     Säurehalo-          genid,    beispielsweise das     Säureehlorid,    ver  wendet werden. Die Umsetzung kann bei  spielsweise in einem indifferenten Lösungs  mittel, vorzugsweise von relativ hohem Siede  punkt, wie Mono,     Di-    oder     Triehlorbenzol,     vorgenommen werden, wobei vorteilhaft bei  erhöhter Temperatur gearbeitet wird.

      <I>Beispiel:</I>  <B>18</B> Teile     ChinOlin-6-earbonsäiire    werden in  <B>600</B> Teilen trockenem Nitrobenzol verteilt und  nach Zufügen von<B>17</B> Teilen     Thionylehlorid     und einer geringen Menge     Pyridin    andert  halb Stunden bei<B>110</B> bis     12011    verrührt. Hier  auf wird mit 48 Teilen     1-Amino-4-(p-sulfo-          d#imethylamido#-benzoylamino)    -'7-chlw-anthra,-         ehinon    versetzt und zwei Stunden bei 120 bis  <B>1300</B> weitergerührt. Der beim Erkalten als  kristallines, rotes Pulver ausfallende Farb  stoff wird gut mit kochendem Alkohol ge  waschen und getrocknet.



  Process for the production of a vat dye. It has been found that a valuable vat dye can be produced if 1-amino-4- (p-sullodimethylamido-ben- voylamino) -7-, chloro-anthraquinone is reacted with a functional derivative of quinoline-6-earbonic acid.



  The new dye dissolves in conc. Sulfuric acid with red color and dyes cotton from a blue-green vat in real pink tones.



  An acid halide, for example the acid chloride, can advantageously be used as the functional derivative of the carboxylic acid mentioned. The reaction can be carried out, for example, in an inert solvent, preferably of a relatively high boiling point, such as mono-, di- or tri-chlorobenzene, advantageously at elevated temperature.

      <I> Example: </I> <B> 18 </B> parts of ChinOlin-6-earbonsäiire are distributed in <B> 600 </B> parts of dry nitrobenzene and after adding <B> 17 </B> parts Thionyl chloride and a small amount of pyridine are stirred for one and a half hours at <B> 110 </B> to 12011. 48 parts of 1-amino-4- (p-sulfod # imethylamido # -benzoylamino) -'7-chlw-anthra-ehinon are added and the mixture is stirred for a further two hours at 120 to 1300 . The dye, which precipitates out as a crystalline, red powder when it cools, is washed well with boiling alcohol and dried.
