Description

  

      verfahren    zur     Darstellung    eines     Farbstoffes    der     Plienonaplitosafraninreihe.     
EMI0001.0005     
  
    Es <SEP> wurde <SEP> gefunden, <SEP> dass <SEP> ein <SEP> wertvoller
<tb>  neuer <SEP> Farbstoff <SEP> entsteht, <SEP> wenn <SEP> man <SEP> 1-.Amino  4-methylainiiio <SEP> - <SEP> 5 <SEP> - <SEP> inetliylbenzol <SEP> -2- <SEP> sulfosänre
<tb>  mit <SEP> 3-Diäthylisorosind(ilin <SEP> - <SEP> 6,13 <SEP> - <SEP> disulfosäure
<tb>  der <SEP> Formel     
EMI0001.0006     
    kondensiert.

   Die entstandene     Phenonaphto-          safranindisulfosäure    enthält eine     Stilfogruppe     in     Orthostellung        zum        Safraninstickstoff        (16-          Stellung),    wodurch die vorzügliche Alkali  echtheit der Färbungen erreicht wird.  



  Der neue Farbstoff ist ein dunkles Pulver,  das in Wasser mit     grünstichig-blatier    Farbe,    in     konaentrierter    Schwefelsäure grasgrün  löslich ist.  



       Beispiel:     30 Teile     p-Sulfophenyl-2-naphtylainin     100     o/oig    werden mit 250 Teilen Alkohol und  26.6 Teilen     Nitrosodiäthylanilin    100     0%ig          während    12 Stunden am     Rückflusskühier    ge  kocht.     I4fan    lässt erkalten, saugt bei 25' ab  und wäscht mit etwas Alkohol nach. Die       3-Diätliylisorosicidulin-13-monosulfosäure    wird  mit 100 Teilen technischen     Bisulfits    nach  dem Verfahren der deutschen Patentschrift  102458 in die     Disulfosäure    übergeführt.

   In  die ca. 800 Volumenteile betragende Lösung  gibt man und siedend heiss 22.2 Teile       1-Amino-4-monomethylamino-5-methylbenzol-          2-sulfosäore   <B>100</B>     o/oig    in 150 Teilen Wasser  und 5. 5 Teilen Soda zu, kocht mehrere  Stunden unter     Rückfluss,    bis eine Probe, in       konzentrierter    Schwefelsäure gelöst,     reiti-grütie     Farbe zeigt.  



  Der mit Kochsalz ausgeschiedene und  getrocknete Farbstoff färbt Wolle im sauren           Bade    in     grünstichig-blauen,    ruhigen Tönen  von vorzüglicher Licht- und     Alkaliechtheit.       Der Farbstoff entspricht der Konstitution

      process for the preparation of a dye of the plienonaplitosafranin series.
EMI0001.0005
  
    <SEP> was found <SEP>, <SEP> that <SEP> a <SEP> more valuable
<tb> new <SEP> dye <SEP> is created, <SEP> when <SEP> man <SEP> 1-.amino 4-methylainiiio <SEP> - <SEP> 5 <SEP> - <SEP> inetliylbenzol <SEP> -2- <SEP> sulfosene
<tb> with <SEP> 3-diethylisorosind (ilin <SEP> - <SEP> 6,13 <SEP> - <SEP> disulfonic acid
<tb> of the <SEP> formula
EMI0001.0006
    condensed.

   The resulting phenonaphthosafranine disulfonic acid contains a stilfo group in the ortho position to the safranine nitrogen (16 position), whereby the excellent alkali fastness of the dye is achieved.



  The new dye is a dark powder that is soluble in water with a greenish-pale color, and grass-green in concentrated sulfuric acid.



       Example: 30 parts of p-sulfophenyl-2-naphtylainin 100% are boiled with 250 parts of alcohol and 26.6 parts of nitrosodiethylaniline 100% for 12 hours on a reflux refrigerator. I4fan lets it cool down, sucks off at 25 'and washes with a little alcohol. The 3-dietliylisorosicidulin-13-monosulfonic acid is converted into disulfonic acid with 100 parts of technical bisulfite by the process of German patent 102458.

   22.2 parts of 1-amino-4-monomethylamino-5-methylbenzene-2-sulfosäore <B> 100 </B>% in 150 parts of water and 5.5 parts are added to the solution, which is approximately 800 parts by volume Add soda, reflux for several hours, until a sample, dissolved in concentrated sulfuric acid, shows red-green color.



  The dye, which is separated out with table salt and dried, dyes wool in an acid bath in calm, greenish-blue tones of excellent light and alkali fastness. The dye corresponds to the constitution
