Description

Verfahren zur Darstellung von Farbstoffen. Zusatz zum Patent 365902**). Durch das Hauptpatent und das Zusatzpatent 368z68 wird ein Verfahren zur Darstellung von Farbstoffen geschützt, welches auf derKondlensation vonOxyna,phthophervazinen (Eurhadolen) bzw. denen Chlorderivaten mit 2, 3 Dichlor-r, 4-naphthochinon- beruht.Process for the representation of dyes. Addition to patent 365902 **). The main patent and the additional patent 368z68 provide a method of representation protected by dyes, which is based on the condensation of Oxyna, phthophervazinen (Eurhadolen) or those chlorine derivatives with 2, 3 dichloro-r, 4-naphthoquinone- based.

Es wurde nun, gefundtn, daß man die genannten Oxynaphthophenazine durch beliebige andere in p-Stellung zum Azinsti.ckstoffdurch Hydroxyl substituierte Azine ersetzen kann. Beispiel. 21 Teile Oxytoluphenazin (erhalten aus 2-Oxy-5-methyl-r, 4-benzochinon und i, 2-Diaminobenzol in essigsaurer Lösung; aus Nitrobenzol braungelbe Nädelchen vom ZersetZttn:gSpUnlit 295°) werden mit 23 Teilen 2, 3-Dichlor-r, 4-naphthochinon, 2o Teilen entwässertem Natriumacetat, r Teil Kupferchlorür und 4oo Teilen Nitrobenzol 2 Stunden auf r2o° erhitzt. Aus der heiß filtrierten Lösung scheiden sich beim Abkühlen gelbe Nädelchen aus, @d!ie bei 266° schmelzen; der Rest des Kondensationsprodukts wird d2trch Abblasen des Lösungsmittels mit Dampf erhalten. Es löst sich in konz. Schwefelsäure orangerot und bildet mit Alkali- und Hydrosulfit eine gelbe Küpe, aus der Baumwolle gelb angefärbt wird.It has now been found that one can use the oxynaphthophenazines mentioned substituted by any others in the p-position to the azine substituent by hydroxyl Can replace azines. Example. 21 parts of oxytoluphenazine (obtained from 2-oxy-5-methyl-r, 4-benzoquinone and i, 2-diaminobenzene in acetic acid solution; from nitrobenzene brown-yellow Needles from decomposition: gSpUnlit 295 °) are mixed with 23 parts of 2, 3-dichloro-r, 4-naphthoquinone, 20 parts of dehydrated sodium acetate, 1 part of copper chloride and 400 parts of nitrobenzene Heated to r2o ° for 2 hours. From the hot filtered solution separate on cooling yellow needles from, @d! ie melt at 266 °; the remainder of the condensation product is obtained by blowing off the solvent with steam. It dissolves in conc. Orange-red sulfuric acid and forms a yellow vat with alkali and hydrosulphite, from which cotton is dyed yellow.
