Description

  

      Verfahren    zur Herstellung einer festen     Diazoazoverbindung.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung einer festen     Diazo-          azoverbindung,    das dadurch gekennzeichnet  ist, dass man aus einer Lösung der     Diazo-          verbindung    des     Aminoazoköi@pers        Parachlor-          benzol-azo-2-amino-1.4-dimethoxybenzol    durch  Zusatz von     Cblorzink    ein festes     Chlorzink-          doppelsalz    der Formel  
EMI0001.0013     
    abscheidet.

    Die so erhaltene feste     Diazoazoverbindung     ist ein rotbraunes Pulver, das sich in Wasser  mit bräunlicher Farbe löst.  



       Beispiel:     Eine aus 292 Teilen des     p-AminoazokZir-          pers        Pai-achlorbenzol-azo-2-amino-1.4-dimeth-          oxybenzol    hergestellte     Diazoniumchloridlösung     wird mit Hilfe von 100 Teilen Chlorzink und  einer genügenden Menge Kochsalz gefällt.  Das abgeschiedene     Ohlorzinkdoppelsalz    wird    getrocknet und gleichmässig mit geeigneten  Verdünnungsmitteln gemischt.



      Process for producing a solid diazoazo compound. The present patent relates to a process for the preparation of a solid diazo-azo compound, which is characterized in that parachlorobenzene-azo-2-amino-1,4-dimethoxybenzene is converted from a solution of the diazo compound of Aminoazoköi @ pers parachlorobenzene-2-amino-1,4-dimethoxybenzene by adding chlorozinc a solid zinc chloride double salt of the formula
EMI0001.0013
    separates.

    The solid diazoazo compound thus obtained is a red-brown powder which dissolves in water with a brownish color.



       Example: A diazonium chloride solution prepared from 292 parts of the p-aminoazokZirper Pai-achlorbenzene-azo-2-amino-1,4-dimethoxybenzene is precipitated with the help of 100 parts of zinc chloride and a sufficient amount of common salt. The separated carbon zinc double salt is dried and mixed evenly with suitable diluents.

PATENTANSPRUCH: Verfahren zur Herstellung einer festen Diazoazoverbindung, dadurch gekennzeichnet, dass man aus einer Lösung der Diazoverbin- dung des Aminoazokörpers Parachlorbenzol- azo-2-amino-1.4-dimethoxybenzol durch Zu satz von Chlorzink ein festes Chlorzitikdoppel- salz der Formel EMI0001.0030 abscheidet. Die so erhaltene feste Diazoazoverbindung ist beständig. Sie ist ein rotbraunes Pulver,- das sich in Wasser mit bräunlicher Farbe löst. Claim: A process for the production of a solid diazoazo compound, characterized in that a solid chlorocite double salt of the formula is obtained from a solution of the diazo compound of the aminoazo body parachlorobenzene-azo-2-amino-1,4-dimethoxybenzene by adding zinc chloride EMI0001.0030 separates. The solid diazoazo compound thus obtained is stable. It is a red-brown powder - which dissolves in water with a brownish color.
