121 Teilen p-Xylidin vereinigt. Das Zwischenprodukt wird isoliert, diazoticrt und in sodaalkalischer Lösung mit 424 Teilen Benzoyl-2.5-aminonaphtl-1.7-disulfosäure gekuppelt. Der Farbstoff wird ausgesalzen, abgesaugt und in sodaalkalischer Lösung weiter vereinigt mit der Diazoverbindung des Zwischenproduktes, das man aus 201 Teilen diazotierter w-Xylidin-o-sulfo- säure und 121 Teilen 1J-Xylidin erhält. Der entstandene Tetrazofarbstoff wird isoliert. Er färbt Baumwolle violett.
In den drei Beispielen können sich 4-Aminobenzoyl-2. 5. aminonaphtol-7-sulfosäure, 1.7und 3.7-disulfosäure und 3-Aminobenzoyl-2.5-aminonaphtol-7-sulfosäure, 1. 7- und 3.7-disulfosaure wechselseitig vertreten.
Bei beliebiger Aniangskomponente kann in Beispiel l Salizylsäure durch Phenol, Azetessigester, I-Naphtol-3-sulfosäure, Azetyl-2.5-aminonaphtolsulfosäure usw. vertreten werden ; in Beispiel 2 kann an Stelle von m-Toluidin, Anilin, 1. 6-Naphtylaminsulfosäure usw. verwendet werden ; in Beispiel 3 endlich kann der Azofarbstoff : Aminoazydil-2.5-aminonaphtoldisulfo-

121 parts of p-xylidine combined. The intermediate product is isolated, diazotized and coupled in a soda-alkaline solution with 424 parts of benzoyl-2,5-aminonaphtl-1,7-disulfonic acid. The dye is salted out, filtered off with suction and further combined in a soda-alkaline solution with the diazo compound of the intermediate, which is obtained from 201 parts of diazotized w-xylidine-o-sulfonic acid and 121 parts of 1J-xylidine. The resulting tetrazo dye is isolated. He dyes cotton purple.
In the three examples, 4-aminobenzoyl-2. 5. aminonaphthol-7-sulfonic acid, 1.7- and 3.7-disulfonic acid and 3-aminobenzoyl-2.5-aminonaphthol-7-sulfonic acid, 1. 7- and 3.7-disulfonic acid alternately represented.
For any anion component, in Example 1, salicylic acid can be represented by phenol, acetoacetic ester, 1-naphthol-3-sulfonic acid, acetyl-2,5-aminonaphthol sulfonic acid, etc.; in Example 2, aniline, 1,6-naphthylamine sulfonic acid, etc. can be used in place of m-toluidine; In Example 3, finally, the azo dye: Aminoazydil-2.5-aminonaphtoldisulfo-
