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.
