  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 196173.    Verfahren zur Herstellung eines neuen     Farbstoffpräpärates:       Es     wurde        gefunden,        dass    man ein neues,  lösliches     Farbstoffpräparaterhält,        wenn    man       auf        1,5-p-Dianissoyldamivo-4.8-,

  dioxyanthra-          chivon    in     Gegenwart    von     Pyridin    2     Mol          Benzoesäure    -     3-.    5     -@dnsülfochlari.@d        einwirken     lässt.  



       Dass        neue        Farbstoffpräparat        stellt        ein     braunes     Pulver    dar,     Idas    sich in Wasser mit       braungelber    Farbe     unter        Bildung    einer       Lösung,        aus        welcher        :

  dusch.        Alkalien    der       Ausgangsfarbstaff    regeneriert     wÜd,        löst.     Das neue     Farbstoffpräparat        kann,    zum Fär  ben oder     Drucken    von     Textilien        verwendet     werden.  



  <I>= Beispiel:</I>       ,53j8        Teile        1,5-p-Dianisoyldiamino-4.8-          dioxyanthrachinon        werden        mit    500     Teilen          Pyrdin        verrührt.    Dazu gibt man 916     Teile          Benzoesäure-3.        ,5-disulfochlorid,        steigert        die     Temperatur auf etwa<B>90'</B> und hält bei 90       bis   <B>95',

  </B>     bis        sich        eine    Probe     in        Wasser    klar  auflöst. Nach dem Abtreiben des     Pyridins       im Vakuum wird     das        Reaktionsprodukt          ,

  durch        Lössen    in     wenig        Wasser        und        Fällen          m        it        i        gesättigter        Kochsalzlösung        in        fester     Form gewonnen.



  <B> Additional patent </B> to the main patent No. 196173. Process for the production of a new dye preparation: It has been found that a new, soluble dye preparation is obtained when one clicks on 1,5-p-Dianissoyldamivo-4.8-,

  dioxyanthrachivon in the presence of pyridine 2 moles of benzoic acid - 3-. 5 - @ dnsülfochlari. @ D can act.



       The new dye preparation is a brown powder, which is dissolved in water with a brownish yellow color to form a solution from which:

  shower. Alkalis of the starting dye are regenerated, dissolves. The new dye preparation can be used for dyeing or printing textiles.



  <I> = Example: </I>, 53j8 parts of 1,5-p-dianisoyldiamino-4,8-dioxyanthraquinone are stirred with 500 parts of pyrdine. 916 parts of benzoic acid-3 are added. , 5-disulfochloride, increases the temperature to about <B> 90 '</B> and holds at 90 to <B> 95',

  </B> until a sample dissolves clearly in water. After the pyridine has been driven off in vacuo, the reaction product,

  obtained in solid form by dissolving in a little water and precipitating with saturated sodium chloride solution.
