Description

  

  Verfahren zur Darstellung eines als     Farbstoff    und     Farbstoffzwischenprodul:t          verwendbaren        Nondensationsproduhtes    der     Anthrachinonreihe.       Es wurde gefunden, dass man ein neues,  als Farbstoff und     Farbstoffzwischeriprodukt     verwendbares     Kondensationsprodukt    der An  thrachinonreihe erhält, wenn man     Cy        anur-          chlorid    und 1 -     4-Diamino.iri.thracliinon    mit  einander umsetzt,

       und    zwar unter Anwen  dung von über einem     Molekül    des letzteren  auf je ein Molekül des ersteren.  



       Beispiel.:     47 Teile 1 -     4-Diaminoantlirachinon    wer  den mit 18 Teilen     Cyanurchlorid    in     Nitro-          benzol        'während    24 Stunden auf etwa.<B>110'</B>  gehalten, unter Zugabe von ca. 40 Teilen     ent-          %vässerten        Natriumacetats    nach etwa. 10  Stunden. Nach Abkühlen wird das ausge  schiedene Kondensationsprodukt durch Fil  tration von der     Nitrobenzolmutterlauge    ge  trennt, gewaschen und, wenn nötig, weiter       gereinigt.    Es ist ein dunkelviolettes Pulver.

    das sich in Wasser nicht, in kaltem und hei  ssem Alkohol nur sehr schwer, in kaltem     Ni-          trobenzol    wenig, in siedendem einigermassen  mit blauroter Farbe löst, in kalte konzen  trierte     Schwefelsäure    eingetragen eine gelbe    Lösung,     verkiipt    eine gelbstickig rote Lösung  bildet und aus dieser. Baumwolle rotstickig  violett färbt.



  Process for the preparation of a nondensation product of the anthraquinone series which can be used as a dye and intermediate dye product. It has been found that a new condensation product of the anthrachinone series which can be used as a dye and intermediate dye product is obtained if one reacts cy anurchloride and 1-4-diamino.iri.thracliinone with one another,

       namely with the application of over one molecule of the latter to one molecule of the former.



       Example: 47 parts of 1-4-diaminoantlirachinon are kept at about .110 ”for 24 hours with 18 parts of cyanuric chloride in nitrobenzene, with the addition of approx. 40 parts of dehydrated sodium acetate after about. 10 hours. After cooling, the precipitated condensation product is separated from the nitrobenzene mother liquor by filtration, washed and, if necessary, purified further. It's a dark purple powder.

    which does not dissolve in water, only very difficultly in cold and hot alcohol, little in cold nitrobenzene, and somewhat bluish-red in boiling water, when added to cold concentrated sulfuric acid a yellow solution forms a yellowish-red solution, which turns into a yellowish-red solution . Cotton dyes red embroidered purple
