Beispiel 1 500 Teile Aluminiumchlorid und 250 Teile Chlorbenzol werden unter Rühren vermischt und darin auf 800C erhitzt. Man leitet 500 Teile Salzsäure-Gas ein und gibt gleichzeitig eine Mischung aus 705 Teilen Phenol und 700 Teilen Acrylnitril innerhalb von ungefähr 5 Stunden zu, danach rührt man noch 15 Stunden bei 80 bis 8500. Anschließend wird die Schmelze unter Rühren auf 250 Teile Eis gegeben, wobei die Temperatur des Reaktionsgemisches 200C nicht übersteigen soll. Nach dem Ablassen der wäßrigen Phase wird das erhaltene ölige Produkt mehrmals mit je 150 Teilen gesättigter Kochsalzlösung gewaschen.Example 1 500 parts of aluminum chloride and 250 parts of chlorobenzene are used mixed with stirring and heated to 800C. 500 parts of hydrochloric acid gas are passed through and at the same time gives a mixture of 705 parts of phenol and 700 parts of acrylonitrile within about 5 hours, then stirred for a further 15 hours at 80 bis 8500. The melt is then poured onto 250 parts of ice with stirring, with the temperature of the reaction mixture should not exceed 200C. After draining In the aqueous phase, the oily product obtained is saturated several times with 150 parts each time Washed saline.

155 Teile dieses Rohproduktes der Formel werden mit 100 Raumteilen Wasser versetzt, mit Ammoniaklösung ileutralisiert und einer Wasserdampfdestillation unterworfen.155 parts of this crude product of the formula 100 parts by volume of water are added, neutralized with ammonia solution and subjected to steam distillation.

Der nicht flüchtige ölige Rückstand wird vom Wasser abgetrennt und mit ungefähr 200 Teilen 36 stiger Salzsäure versetzt. Man rührt das Gemisch etwa 20 Stunden bei 300C, setzt dann 500 Teile Eis und 200 Teile 50 ßige Natronlauge zu und säuert erneut mit Salzsäure auf pH 1 bis 3 an. Das kristallin ausfallende Produkt der Formel wird abgesaugt und mit kaltem Wasser gewaschen. Man erhält nach dem Trocknen etwa 80 Teile eines farblosen Pulvers, das bei 119 bis 12100 schmilzt.The non-volatile oily residue is separated from the water and mixed with about 200 parts of 36 hydrochloric acid. The mixture is stirred for about 20 hours at 30 ° C., then 500 parts of ice and 200 parts of 50% sodium hydroxide solution are added and the mixture is acidified again to pH 1 to 3 with hydrochloric acid. The crystalline precipitating product of the formula is suctioned off and washed with cold water. After drying, about 80 parts of a colorless powder which melts at 119 to 12,100 are obtained.

67 Teile 2-Aminonaphthalin-5-sulfonsäure werden in ungefähr 180 Raumteilen Wasser durch Zugabe von 33 Teilen 50 zeiger Natronlauge bei OH 10 bis 11,5 gelöst. Dazu gibt man 95 Raumteile einer 23 eigen Natriumnitritlösung und läßt das erhaltene Gemisch unter rühren zu vorgelegten 300 Teilen Eis und 95 Raumteilen Salzsäure (30 «ig) laufen. Man rührt 2 Stunden bei 5 bis 1000 und tropft dann 36 Teile p-Xylidin zu, die in 750 Raumteilen asser und 30 Raumteilen 30 ygiger Salzsäure gelost sind (ein etwa vorhandener Überschuß an salpetriger Säure wurde zuvor wie üblich zerstört). Dann wird der pH-Wert der Kupplungsmischung durch Zugabe von Natronlauge (25 doig) oder Natriumacetat-Lösung innerhalb von 2 Stunden auf 4,5 bis 5,2 angehoben. Der erhaltene Aminoazofarbstoff der Formel wiS abgesaugt.67 parts of 2-aminonaphthalene-5-sulfonic acid are dissolved in approximately 180 parts by volume of water by adding 33 parts of 50-point sodium hydroxide solution at OH 10 to 11.5. 95 parts by volume of 23 sodium nitrite solution of its own are added and the mixture obtained is allowed to run, with stirring, to 300 parts of ice and 95 parts by volume of 30% hydrochloric acid. The mixture is stirred for 2 hours at 5 to 1000 and then 36 parts of p-xylidine are added dropwise, which are dissolved in 750 parts by volume of water and 30 parts by volume of 30% hydrochloric acid (any excess of nitrous acid was previously destroyed as usual). Then the pH of the coupling mixture is raised to 4.5 to 5.2 within 2 hours by adding sodium hydroxide solution (25 doig) or sodium acetate solution. The resulting aminoazo dye of the formula wiS sucked off.

142 TeIle dieses Aminoazofarbstoffes werden als feuchte Paste bei 8000 in 3C;0 Raumteilen Wasser durch Zugabe von Natronlauge bei pH 9 gelöst. Nach Versetzen mit 132 Raumteilen einer 23 %igen i;Tatriumnitritlösung wird das Gemisch unter sehr gutem Rühren zu vorgelegten 2 000 Teilen Eis, 18 Raumteilen 30 %iger Salzsäure und 500 Teilen Wasser gegeben. Man rührt die Diazotierungsmischung 2 Stunden bei 20 bis 230C und zerstört überschüssige, salpetrige Säure dann wie üblich. Die so erhaltene Suspension wird nun zu einer Lösung aus 66 Teilen p-Hydroxyphenylpropionsäureamid in 1 000 Raumtel en zu Cn Wasser, 40 Teilen 50 Xiger Natronlauge und 100 Teilen Soda gegeben.142 parts of this aminoazo dye are obtained as a moist paste 8000 dissolved in 3C; 0 parts by volume of water by adding sodium hydroxide solution at pH 9. To Add 132 parts by volume of a 23% strength i; sodium nitrite solution to the mixture with very good stirring to 2,000 parts of ice, 18 parts by volume, 30% strength Hydrochloric acid and 500 parts of water are added. The diazotization mixture is stirred for 2 hours at 20 to 230C and destroyed excess, nitrous acid then as usual. The suspension obtained in this way now becomes a solution of 66 parts of p-hydroxyphenylpropionamide in 1,000 parts of space to Cn water, 40 parts of 50% sodium hydroxide solution and 100 parts Given soda.

Die Kupplungstemperatur beträgt etwa 10 bis 20°C, der pH-Wert soll nicht unter 9 abfallen. Nach beendeter Kupplung wird der entstandene Farbstoff der Formel mit 500 bis 1 000 Teilen Natriumchlorid ausgesalzen und dann abgesaugt und getrocknet. Man erhält etwa 200 Teile eines braunen Pulvers, das Polyamidfasern in kräftigen gelbbraunen Tönen mit guten Echtheiten färbt.The coupling temperature is around 10 to 20 ° C, the pH value should not drop below 9. After the coupling has ended, the resulting dye is of the formula salted out with 500 to 1,000 parts of sodium chloride and then filtered off with suction and dried. About 200 parts of a brown powder are obtained which dyes polyamide fibers in strong yellow-brown shades with good fastness properties.

Beispiel 2 12,4 Teile der hminoazokomponente der Formel werden als wäßrige Paste in 100 Raumteilen Wasser von etwa 600C durch Zugabe von Natronlauge bis zur stark alkalischen Reaktion (pH 9,5 bis 10,5) gelöst. Man setzt 14 Raumteile einer Natriumnitritlösung (23 %ig) zu und läßt das Gemisch unter guter Rührung zu vorgelegten 300 Teilen Eis und 13 Raumteilen 30 zeiger Salzsäure laufen. Man rührt 3 Stunden bei 20 bis 2500 und zerstört dann einen etwa vorhandenen Überschuß an salpetriger Säure wie üblich. Das erhaltene Diazoniumsalzgemisch wird zu einer auf 500 abgekühlten Lösung aus 6,7 Teilen 4-(4'-Hydroxyphenyl)-butanon-2 in 150 Raumteilen Wasser, 4 Teilen Natronlauge (50 Xig) und 10 Teilen Soda gegeben.Example 2 12.4 parts of the hminoazo component of the formula are dissolved as an aqueous paste in 100 parts by volume of water at about 600C by adding sodium hydroxide solution to a strongly alkaline reaction (pH 9.5 to 10.5). 14 parts by volume of a sodium nitrite solution (23%) are added and the mixture is allowed to run, with thorough stirring, to 300 parts of ice and 13 parts by volume of 30 point hydrochloric acid. The mixture is stirred for 3 hours at 20 to 2500 and then any excess of nitrous acid is destroyed as usual. The resulting diazonium salt mixture is added to a solution, cooled to 500, of 6.7 parts of 4- (4'-hydroxyphenyl) -butanone-2 in 150 parts by volume of water, 4 parts of sodium hydroxide solution (50% strength) and 10 parts of soda.

Der pH-Wert der Kuptlungslösung soll dabei nicht unter 9 abfallen, die Temperatur 25°C nicht übersteigen. Nach beendeter Kupplung wird der Farbstoff der Formel durch Zusatz von ungefähr 100 bis 150 Teilen Natriumchlorid ausgesalzen. Man rührt über Nacht, saugt den ausgefallenen Farbstoff ab und' trocknet ihn. Nan erhält ein dunkelbraunes Pulver, das sich in Wasser mit brauner Farbe löst und Polyamidgewebe in kräftigen, braunen Tönen mit guten Echtheiten färbt.The pH of the solution should not drop below 9 and the temperature should not exceed 25 ° C. When the coupling is complete, the dye has the formula salted out by adding about 100 to 150 parts of sodium chloride. The mixture is stirred overnight, the dyestuff which has precipitated out is suctioned off and it is dried. Nan receives a dark brown powder that dissolves in water with a brown color and dyes polyamide fabric in strong, brown shades with good fastness properties.
