Description
Verfahren zur Herstellung einer chlorhaltigen Aldehydverbindung. Vorliegendes Patent bezieht sich auf ein Verfahren zur Darstellung von 6-Äthoxy-3- chlorthionaphthen-2-aldehyd, dadurch gekenn zeichnet, dass man 6-Äthoxythionaphthen, eine Formylverbindung eines aromatischen sekundären Amins und ein chlorhaltiges sau- resKondensationsmittel aufeinander einwirken lässt.
Der neue Körper kristallisiert aus Alko hol in Form braungelblicher Nadeln vom Schmelzpunkt etwa 166 . Er zeigt die für Aldehyde charakteristischen Eigenschaften und löst sich in Schwefelsäure mit olivgel- ber Farbe. Der so gewonnene Aldehyd soll als Zwischenprodukt zur Herstellung von Farbstoffen, pharmazeutischen Produkten und Riechstoffen Verwendung finden.
<I>Beispiel:</I> Trägt man in ein Reaktionsgemisch von 13,5 kg Formylmonomethylanilin und 15,3 kg Phosphoroxychlorid 9,4 kg 6-Äthoxythio- naphthen ein, wobei man die Reaktionstem peratur nicht über 60 steigen lässt, so ge langt man zu einem chlorhaltigen Al dehyd, der in üblicher Weise isoliert wird.
Ersetzt man in diesem Beispiel das For- mylmonomethylanilin durch die Formylver- bindungen anderer sekundärer Amine, so ge langt man in gleicher Weise zu dem be schriebenen chlorhaltigen Aldehyd.
Process for the preparation of a chlorine-containing aldehyde compound. The present patent relates to a process for the preparation of 6-ethoxy-3-chlorothionaphthen-2-aldehyde, characterized in that 6-ethoxythionaphthene, a formyl compound of an aromatic secondary amine and a chlorine-containing acidic condensation agent act on one another.
The new body crystallizes from alcohol in the form of brownish-yellow needles with a melting point of around 166. It shows the properties characteristic of aldehydes and dissolves in sulfuric acid with an olive yellow color. The aldehyde obtained in this way is intended to be used as an intermediate for the production of dyes, pharmaceutical products and fragrances.
<I> Example: </I> If you add 9.4 kg of 6-ethoxythio naphthene to a reaction mixture of 13.5 kg of formylmonomethylaniline and 15.3 kg of phosphorus oxychloride, the reaction temperature not being allowed to rise above 60, so ge if you reach a chlorine-containing aldehyde, which is isolated in the usual way.
If the formylmonomethylaniline in this example is replaced by the formyl compounds of other secondary amines, the chlorine-containing aldehyde described is obtained in the same way.
