Description
Verfahren zur Darstellung eines Derivates des Naphthsultons. Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung von 4-(p-Toluol- sulfonyl)-napht'hsulto#n. Das Verfahren ist dadurch gekennzeichnet, dass - man auf Naphthsulton ein p-Toluolsulfo-halogenid einwirken lässt.
Das neue Sulfon bildet Kristalle vom Schmelzpunkt 214-217 und soll als Zwi- schenprodukt für die Herstellung von Farb stoffen dienen.
Beispiel: In die viskose Lösung von 103 Teilen Naphthsulton und 100 Teülen Aluminium chlorid in 300 Teilen Trichlorbenzol trägt man 148 Teile 4-Methyl-benzol-l-elüfoehlorid ein und erhitzt innert 1 Stunde auf 105 , zersetzt die klare, viskose Lösung mit Eis und Salzsäure, behandelt mit Wasserdampf und saugt schliesslich das kristallin abge- schiedene Sulfon ab.
Nach einmaligem Um kristallisieren aus Chloroform und Alkohol erhält man 160 Teile 4-(p-T.oluo-Isulfony1)- naphthsulton als weisses Pulver vom Schmelz- punkt 214-217 , entsprechend einer Aus beute von<B>89%</B> der Theorie. Nach noch maligem UmkristaIlisieren aus Chloroform! Alkohol ist das Sulfon völlig rein; es schmilzt dann bei 215=216.,5 .
Process for the preparation of a derivative of naphthsultone. The present patent is a process for the preparation of 4- (p-toluenesulfonyl) -naphth'hsulto # n. The process is characterized in that - a p-toluenesulfo halide is allowed to act on naphthsultone.
The new sulfone forms crystals with a melting point of 214-217 and is intended to serve as an intermediate in the manufacture of dyes.
Example: In the viscous solution of 103 parts of naphthsultone and 100 parts of aluminum chloride in 300 parts of trichlorobenzene, 148 parts of 4-methylbenzene-1-elüfoehlorid are added and heated to 105 within 1 hour, the clear, viscous solution is decomposed with ice and Hydrochloric acid, treated with steam and finally sucks off the crystalline sulfone.
After recrystallizing once from chloroform and alcohol, 160 parts of 4- (pT.oluo-Isulfony1) -naphthsultone are obtained as a white powder with a melting point of 214-217, corresponding to a yield of 89% of theory . After repeated recrystallization from chloroform! Alcohol is completely pure the sulfone; it then melts at 215 = 216., 5.
