Description

Beispielexample

Eine Lösung von 264 g 2,6-Dibrom-4-methyI-anilin in 125 ml 60%iger Schwefelsäure wird bei 38 bis 40° C mit 17 ml einer 42%igen Nitrosylschwefelsäure diazotiert. Man rührt noch 60 Minuten bei 40° C und fügt dann die Lösung der Diazokomponente bei 0 bis 5° C zu einer Suspension der äqutmolaren Menge an 3-Diallylaminomethansulfon-anilid und 2 g Amidosulfonsäure in 200 ml Wasser. Durch Zufügen von Natriumacetat wird der ab und wäschtA solution of 264 g of 2,6-dibromo-4-methyI-aniline in 125 ml of 60% sulfuric acid is at 38 to 40 ° C with 17 ml of a 42% nitrosylsulfuric acid are diazotized. The mixture is stirred for a further 60 minutes at 40 ° C. and then the Solution of the diazo component at 0 to 5 ° C. to form a suspension of the equimolar amount of 3-diallylaminomethanesulfon anilide and 2 g of sulfamic acid in 200 ml of water. By adding sodium acetate, the off and washes

Das so erhaltene 3-Methansulfonamido-4-(2',6'-dibrom-4'-methyl-phenylazo)-N,N-diallylanilin wird in üblicher Weise mit Zinkcyanid und Kupfercyanid in Dimethylformamid umgesetzt. Man fällt mit Wasser aus und saugt den entstandenen Dicyanazofarbstoff ab. Er färbt Polyesterfasern in roter Nuance.The 3-methanesulfonamido-4- (2 ', 6'-dibromo-4'-methyl-phenylazo) -N, N-diallylaniline obtained in this way is reacted in the usual way with zinc cyanide and copper cyanide in dimethylformamide. One precipitates with water and sucks off the resulting dicyanazo dye. It dyes polyester fibers in a red shade.
