Description
Verfahren zur Herstellung einer Diazoaminoverbindung. Es wurde .gefunden, dass man durch Kupp lung von Cyanamidearbonsäure bezw. ihren Salzen mit substituierten aromatischen Di- azoniumverbindungen, zweckmässig in alka lischem Medium, Produkte erhält, die wert volle Komponenten für @die Herstellung von Farbstoffen :darstellen.
Als substituierte aro matische Diazoverbindungen kommen ins- besondere in Betrassht: :durch Halogen-, Nitro-, Alkyl- und Alkogygruppen substi tuierte Körper, insbesondere ,der Benzolreihe, Aminoazoverbindungen, Amine der Carba- zole oder Anthrachinone usw., d. h.
also ins besondere Basen, wie sie zur Herstellung von Körpern der Eisfarbenreihe üblich sind.
Gegenstanddesvorliegenden Patentes istein '\'erfahren zur Herstellung einer neuen Dia.zo- aminoverbindung,dadurchgekennzeichnet,dass man diazotiertes 1-T.ri±luormethyl-3-amino- phenyl-4-äthylsulfon mit dem Natriumsalz ,der Cyanamidearbonsäure kondensiert.
Das so erhältliche Umsetzungsprodukt ist schwach gefärbt und in Wasser leicht löslich. Es ist ein wertvolles Produkt zur Herstellung von Azofarbstoffen. <I>Beispiel:
</I> 25,3 Gewichtsteile 1-Trifluormethyl-3- aminophenyl-4-äthylsulfon werden in der üblichen Weise diazotiert. Die Diazolösung wird in eine Lösung von 18 Gewichtsteilen Cyanamidearbonsäurenatrium in 150 Ge- wichtsteilen 10 % iger Natriumkarbonatlösung eingegeben. Die so gebildete Diazoamino- verbindung wird ausgoesalzen und isoliert.
Nach dem Trocknen erhält man sie als schwach gefärbte Kristalle.
Process for producing a diazoamino compound. It was found that by coupling cyanamidearboxylic acid respectively. Their salts with substituted aromatic diazonium compounds, expediently in an alkaline medium, receive products that are valuable components for the production of dyes.
Substituted aromatic diazo compounds are in particular:: Bodies substituted by halogen, nitro, alkyl and alkogy groups, in particular from the benzene series, aminoazo compounds, amines of the carbazoles or anthraquinones, etc., d. H.
So in particular bases, as they are usual for the production of bodies of the ice color series.
The subject of the present patent is an '\' experienced in the production of a new dia.zo-amino compound, characterized in that diazotized 1-tri ± luoromethyl-3-aminophenyl-4-ethylsulfone is condensed with the sodium salt, cyanamidearboxylic acid.
The reaction product obtainable in this way is slightly colored and easily soluble in water. It is a valuable product for the manufacture of azo dyes. <I> example:
</I> 25.3 parts by weight of 1-trifluoromethyl-3-aminophenyl-4-ethylsulfone are diazotized in the usual way. The diazo solution is added to a solution of 18 parts by weight of sodium cyanamidearboxylic acid in 150 parts by weight of 10% sodium carbonate solution. The diazoamino compound formed in this way is salted out and isolated.
After drying, they are obtained as slightly colored crystals.
