  Verfahren zur Herstellung einer festen     Diazoazoverbindung.     
EMI0001.0002     
  
    Vorliegendes <SEP> Patent <SEP> bezieht <SEP> sich <SEP> auf <SEP> ein
<tb>  Verfahren <SEP> zur <SEP> Herstellung <SEP> einer <SEP> festen <SEP> Di   <  < zoa.zoverbindung, <SEP> das <SEP> dadurch <SEP> g;eken.nzeich  net <SEP> ist, <SEP> dass <SEP> man <SEP> aus <SEP> einer <SEP> Lösung <SEP> der
<tb>  Di.azove <SEP> rbindung <SEP> des <SEP> l@.minoa,zokörpers <SEP> Para  nitrob.enzol <SEP> - <SEP> azo <SEP> - <SEP> ? <SEP> - <SEP> amino <SEP> -1. <SEP> 4 <SEP> - <SEP> dimethoxy  benzol <SEP> durch <SEP> Zusatz <SEP> von <SEP> Hochsalz <SEP> ein <SEP> festes
<tb>  Diazoniumchlorid <SEP> der <SEP> Formel:

       
EMI0001.0003     
         abscheidet.     Die so erhaltene feste     Diazoazoverbindung          it    ein     braunes    Pulver, das sich in     NVasser     mit bräunlicher Farbe löst. Sie besitzt 'bei       guter    Löslichkeit eine gute Haltbarkeit.  



  <I>Beispiel:</I>  Eine     aus        30?    Teilen des     p-Aminoa.zo-          körpers:        Pa.ra.nitrobenzo:l    -     azo    - 2 -     amino-          i    .     -1    -     dimethoxybenzol    hergestellte     Di-          a.zoniumchloridlösung    wird     aasgesalzen    und  das in kristalliner Farm     augfallende    Di-         a-zoniumchlorid    filtriert und bei etwa 40 bis  50   getrocknet.



  Process for producing a solid diazoazo compound.
EMI0001.0002
  
    The present <SEP> patent <SEP>, <SEP> refers to <SEP>
<tb> Method <SEP> for <SEP> production <SEP> of a <SEP> fixed <SEP> Di <<zoa.zo connection, <SEP> the <SEP> thereby <SEP> g; eken.mark net <SEP> is, <SEP> that <SEP> man <SEP> from <SEP> a <SEP> solution <SEP> the
<tb> Di.azove <SEP> rbinding <SEP> of <SEP> l @ .minoa, zokörpers <SEP> Para nitrob.enzol <SEP> - <SEP> azo <SEP> - <SEP>? <SEP> - <SEP> amino <SEP> -1. <SEP> 4 <SEP> - <SEP> dimethoxy benzene <SEP> with <SEP> addition <SEP> of <SEP> high salt <SEP> a <SEP> solid
<tb> Diazonium chloride <SEP> of the <SEP> formula:

       
EMI0001.0003
         separates. The solid diazoazo compound thus obtained is a brown powder which dissolves in water with a brownish color. It has a good shelf life with good solubility.



  <I> Example: </I> One out of 30? Parts of the p-Aminoa.zo- body: Pa.ra.nitrobenzo: l - azo - 2 - amino- i. -1-dimethoxybenzene produced di-a.zonium chloride solution is carrion salted and the precipitating di-a-zonium chloride in crystalline form filtered and dried at about 40 to 50.
