372 Teile 4-Aminobenzoesäure-2'-äthylhexylamid werden mit 4600 Teilen Wasser und 6OO Raumteilen 15 $iger Salzsäure versetzt und bis zur Lösung gerührt. Dann setzt man weitere 500 Raumteile 15 $iger Salzsäure und. danach soviel Eis und Wasser zu, daß das Volumen des Gemisches etwa 7500 Raumteile und die Temperatur etwa 5 bis 80C beträgt. Man läßt rasch 450 Raumteile einer 23 Jöigen Natriumnitritlösung zulaufen und rührt die meist klare Lösung etwa JO bis 60 Minuten bei etwa 5 - 12°C. Die Diazoniumsalzlösung gibt man zu einer auf 0 bis 5 C abgekühlten Lösung von 226 Teilen 2i6-Dihydroxy-3-cyan-methylpyridin in etwa 8OOO Teilen Wasser und 68 Teilen Natronlauge. Während der Kupplung setzt man etwa J500 Teile Soda so zu, daß der pH-Wert des Gemisches stets größer als 6,5 ist. Nach beendeter Kupplung wird die wäßrige Farbstoffdispersion bei einem pH-Wert von etwa 6 bis 9 auf 80 C aufgeheizt. Man rührt das Gemisch etwa 1 Stunde bei dieser Temperatur, saugt dann ab und wäscht mit Wasser. Man erhält etwa 600 Teile eines kristalliner. Pulvers der Formel372 parts of 4-aminobenzoic acid-2'-ethylhexylamide are mixed with 4600 parts of water and 600 parts by volume of 15% hydrochloric acid and the mixture is stirred until it dissolves. Then you put another 500 parts by volume of 15 $ hydrochloric acid and. thereafter so much ice and water such that the volume of the mixture is about 7500 parts by volume and the temperature is about 5 to 8 0 C. 450 parts by volume of a 23% sodium nitrite solution are quickly run in and the usually clear solution is stirred for about 50 to 60 minutes at about 5-12 ° C. The diazonium salt solution is added to a solution, cooled to 0 to 5 ° C., of 226 parts of 2 i 6-dihydroxy-3-cyano-methylpyridine in about 800 parts of water and 68 parts of sodium hydroxide solution. During the coupling, about 500 parts of soda are added so that the pH of the mixture is always greater than 6.5. After coupling has ended, the aqueous dye dispersion is heated to 80.degree. C. at a pH of about 6 to 9. The mixture is stirred for about 1 hour at this temperature, then filtered off with suction and washed with water. About 600 parts of a crystalline are obtained.
