Description

  

  Verfahren zur     Darstellung    einer     Diazoamiuoverbindung.       Durch das. Hauptpatent ist die Darstel  lung einer     Diazoaminoverbindung    geschützt,  die dadurch gekennzeichnet ist, dass man die       Diazoverbindung    aus     3-Ghloranilitr    auf 2  Amirro-4-sulfobenzoesärrre einwirken lässt.  



  Gegenstand vorliegender Erfindung ist  nun ein Verfahren zur Darstellung einer       Diazoaminoverbindung,    dadurch gekennzeich  net, dass man die     Diazoverbindung        aus    2 . 5  Dichlor-l-aminobenzol auf     1-Methyl-4-amino-          .berrzol-2-sulfanilid    einwirken lässt.    <I>Beispiel:</I>  Die     Diazoverbindung    aus 163 Gewichts  teilen 2 .     5-Dichlor-l-aminoberrzol    lässt man  in eine salzsaure Lösung von 26<B>2</B> Gewichts  teilen     1-Methyl-4-aminobenzol-2-sulfanilid    ein  laufen und stumpft allmählich mit Natrium  acetat oder Natriumkarbonat ab, bis die Lö  sung gegen Kongo nicht mehr sauer reagiert.

    Nach einigen Stunden ist die     Diazoverbin-          dung    verschwunden und die     Diazoaminover-          bindung    von der Formel  
EMI0001.0018     
    abgeschieden. Man löst letztere nun in Na  tronlauge und salzt mit     Natriumchlorid    aus,  wobei das     Natriumsalz    zunächst als harzige  Masse sich abscheidet. Nach dem     Abfiltrieren       und dem Trocknen bildet es ein gelblich  braunes, in Wasser leicht lösliches Pulver,  dessen Lösung durch Säuren wieder in die  Ausgangskomponenten gespalten wird.      Es soll in der Färberei- und. Druckerei  praxis, sowie als Schädlingsbekämpfungsmittel  Verwendung finden.



  Method for preparing a diazoamino compound. The representation of a diazoamino compound is protected by the main patent, which is characterized in that the diazo compound of 3-chloroanilitrile is allowed to act on 2 amirro-4-sulfobenzoesärrre.



  The present invention now relates to a process for the preparation of a diazoamino compound, characterized in that the diazo compound from FIG. 5 dichloro-l-aminobenzene to act on 1-methyl-4-amino- .berrzol-2-sulfanilide. <I> Example: </I> The diazo compound made up of 163 parts by weight 2. 5-dichloro-l-aminoberrzol is allowed to run into a hydrochloric acid solution of 26 parts by weight of 1-methyl-4-aminobenzene-2-sulfanilide and gradually blunted with sodium acetate or sodium carbonate until the Solution against Congo no longer reacts sour.

    After a few hours the diazo compound has disappeared and the diazoamino compound from the formula
EMI0001.0018
    deposited. The latter is now dissolved in sodium hydroxide solution and salted out with sodium chloride, the sodium salt initially separating out as a resinous mass. After filtering off and drying, it forms a yellowish brown powder which is easily soluble in water, the solution of which is broken down again into the starting components by acids. It is said to be used in dyeing and. Printing practice and as a pesticide use.
