Bei der Herstellung der Farbstoffe der allgemeinen Formell erfolgt die Diazotierung der Amine wie üblich. Die Kupplung wird ebenfalls wie üblich in wäßrigem Medium, gegebenenfalls unter Zusatz von Lösungsmitteln, bei schwach- bis starksaurer Reak- 5 tion durchgeführtIn the preparation of the dyes of the general formula, the amines are diazotized as common. The coupling is also carried out as usual in an aqueous medium, optionally with the addition of Solvents, for weakly to strongly acidic reac- 5 tion carried out
Die Herstellung der Kupplungskomponenten der allgemeinen Formal IH ist im Prinzip in der deutschen Offenlegungsscbrift 2062 717 beschrieben, die Angaben dort gelten hier sinngemäß. ι οThe manufacture of the coupling components of the general formal IH is described in principle in the German Offenlegungsscbrift 2062 717, the Information there applies accordingly here. ι ο
Enthalten die erfindungsgemäßen Farbstoffe der Formel I eine Estergruppe in den Rest R, so kann die Herstellung der Verbindungen der Formel I im Prinzip nach dem angegebenen Verfahren erfolgen, wenn die entsprechende Estergruppe schon in der Kupp- 15 lungskomponente enthalten ist. In manchen Fällen ist es aber auch zweckmäßig, den Säurerest (Acyl) in den fertigen Farbstoff der Formel I einzuführen. Dazu eignen sich die freien Säuren, ihre Anhydride, Chloride oder Ester, wobei zweckmäßigerweise inerte 20 Verdünnungs- oder Lösungsmittel, wie Mono-, Dioder Trichlorbenzol, Tetrahydrofuran, Dioxan, Dimethylformamid, N-Methylpyrrolidon oder Pyridin Zugesetzt werden.If the dyes of the formula I according to the invention contain an ester group in the radical R, the compounds of the formula I can in principle be prepared by the process indicated if the corresponding ester group is already contained in the coupling component. In some cases, however, it is also expedient to introduce the acid radical (acyl) into the finished dye of the formula I. For this purpose, the free acids, their anhydrides, chlorides or esters are suitable, and advantageously 20 inert diluent or solvent, such as mono-, di- or trichlorobenzene, tetrahydrofuran, dioxane, dimethylformamide, N-methylpyrrolidone or pyridine are.
Bei der Veresterung mit freien Säuren kann es von ^ Vorteil sein, anorganische oder organische Katalysatoren, z. B. HCl-Gas oder p-Toluolsulfonsäure, zujzusetzen und das entstehende Wasser aus dem Reaktionsgemisch durch Verdampfen entweichen zu lassen. Werden Säureanhydride oder -chloride zur Vereste- 30 rung eingesetzt, so können als Lösungsmittel in speziellen Fällen auch die betreffenden Säuren verwendet werden. So läßt sich die Umsetzung mit Acetanhydrid in Eisessig durchführen. Bei der Verwendung von Säurechloriden als Veresterungsmittel ist es von Vor- 35 teil, dem Reaktionsgemisch säurebindende Mittel hinzuzusetzen, z. B. Natriumcarbonat oder -acetat, Magnesiumoxid oder Pyridin. Als Veresterungsmittel »eien im einzelnen beispielsweise genannt: Ameisensäure, Essigsäure, Chloressigsäure sowie die Ester, 40 Anhydride oder Chloride dieser Säuren, weiterhin Chlorameisensäureäthylester oder Diketen.In the esterification of free acids, it may be advantageous ^, inorganic or organic catalysts, eg. B. HCl gas or p-toluenesulfonic acid, add and allow the water formed to escape from the reaction mixture by evaporation. If acid anhydrides or chlorides are used for the esterification, the relevant acids can also be used as solvents in special cases. For example, the reaction with acetic anhydride can be carried out in glacial acetic acid. When using acid chlorides as esterifying agents, it is advantageous to add acid-binding agents to the reaction mixture, e.g. B. sodium carbonate or acetate, magnesium oxide or pyridine. Examples of esterifying agents mentioned in detail are: formic acid, acetic acid, chloroacetic acid and the esters, anhydrides or chlorides of these acids, and also ethyl chloroformate or diketene.
