Description

  

  Verfahren zur Herstellung einer     Diazoaminoverbindung.       Es wurde gefunden,     -dass    man durch Kupp  lung von     Cyanamidcarbonsäure        bezw.    ihren  Salzen mit     -substituierten    aromatischen     Di-          a.zoniumverbindun,gen,    zweckmässig in alka  lischem     Medium,    Produkte erhält, die wert  volle Komponenten für die Herstellung von  Farbstoffen darstellen.

   Als     substituiert--        aro-          matisohe        Diazoverbindun,gen    kommen ins  besondere in Betracht: durch Halogen-,       Nitro-,        Alkyl-    und     Alkogygruppen        substi-          tuierte        Körper,        insbesondere    der     Benzolreihe,          Aminoazoverbindungen,    Amine der     Ciarba-          zole    oder     Anthraehin        one    usw.,

   das heisst also       insbesondere    Basen, wie sie zur     Herstellung     von     Körpern    .der     Eisfarbenreihe    üblich     sind.     



       Gegenstand    vorliegender     Erfindung    ist  ein verfahren zur     Herstellung        einer        neuen          Diazoaminoverbindung"dadureh        gekennzeich-          net,        da.ss    man     diazotiertes        1-Trifluor-methyl-          4-ch.lor-3-aminolbenzol    mit dem     Natriumsalz     der     Cyana.midearbonsäure    kondensiert.  



  Das so erhältliche Umsetzungsprodukt  stellt schwach     .gefärbte,    in     Wasser    leicht lös  liche Kristalle dar und ist ein wertvolles  Produkt zur     Herstellung    von     Azofarbstoffen.       <I>Beispiel:

  </I>    21     Gewichtsteile        1-Trifluormethyl-4-chlor-          3-aminobenzol    werden in der üblichen Weise       diazotiert.    Die     Diazolösung        wird    in     eine          Lösung    von 18     Gev,ichtsteilen        Cyanamid-          carbonsäurenatrium    in<B>150</B>     Gewichtsteilen     10 %     iger        Natriumkarbünatlösung    eingegeben.

    Die so gebildete     Dia.zoaminoverbindung    wird       ausgesalzen    und isoliert. Nach dem Trocknen  erhält man     sie    als     schwachgefärbte    Kristalle.



  Process for producing a diazoamino compound. It has been found -that you or by coupling of cyanamidecarboxylic acid. their salts with -substituted aromatic di- a.zoniumverbindungen, gene, expediently in an alkaline medium, receives products that are valuable components for the production of dyes.

   Substituted aromatic diazo compounds are particularly suitable: bodies substituted by halogen, nitro, alkyl and alkogy groups, in particular of the benzene series, aminoazo compounds, amines of the ciarabazole or anthraquinones, etc.,

   That means, in particular, bases such as are customary for the production of bodies of the ice color series.



       The present invention relates to a process for the preparation of a new diazoamino compound "dadureh marked, that diazotized 1-trifluoro-methyl-4-chloro-3-aminolbenzene is condensed with the sodium salt of cyana.midearboxylic acid.



  The reaction product obtainable in this way is weakly colored, easily water-soluble crystals and is a valuable product for the production of azo dyes. <I> example:

  </I> 21 parts by weight of 1-trifluoromethyl-4-chloro-3-aminobenzene are diazotized in the usual way. The diazo solution is added to a solution of 18 parts by weight of cyanamide-carboxylic acid sodium in 150 parts by weight of 10% sodium carbonate solution.

    The diazoamino compound thus formed is salted out and isolated. After drying, they are obtained as pale colored crystals.
