Description

Verfahren zur Darstellung von violetten Farbstoffen der Triarylmethanreihe. Zusatz zum Patent 44o 892. In dem Hauptpatent 44o 8g2 ist ein Verfahren zur Darstellung' von violetten Farbstoffen der Triarylmethanreihe aus i Mol. 4a 4@-Tetraalkyldiaminobenzophenon und i Mol. eines arylierten oder eines gleichzeitig arylierten und alkylierten Äthylendiamine beschrieben. Wie weiter gefunden wurde, tritt Di-i-naphthyläthylendiamin im Gegensatz zu den in dem Hauptpatent angegebenen Äthylendiaminderivaten außer mit i Mol. auch mit 2 M01. 4, 4'-Tetraalkyldiaminobenzophenon in Reaktion, wobei blauviolette Farbstoffe entstehen von der Konstitution: Die Farbstoffe stehen in ihren färberischen Eigenschaften den Farbstoffen des Hauptpatents nahe. Durch Sulfierung lassen sich die basischen Farbstoffe in saure Wollfarbstoffe umwandeln.Process for the preparation of violet dyes of the triarylmethane series. Additional patent 44o 892. In the main patent 44o 8g2 an arylated or simultaneously arylated and alkylated Äthylendiamine is a process for the preparation 'of violet dyes of the triarylmethane from i Mol. 4a @ 4 -Tetraalkyldiaminobenzophenon and i Mol. Described. As was further found, di-i-naphthylethylenediamine, in contrast to the ethylenediamine derivatives specified in the main patent, occurs not only with 1 mole, but also with 2 M01. 4,4'-Tetraalkyldiaminobenzophenone in reaction, whereby blue-violet dyes arise from the constitution: The coloring properties of the dyes are close to the dyes of the main patent. The basic dyes can be converted into acidic wool dyes by sulphonation.

Beispiel. 54 Teile 4, 4'-Tetramethyldiaminobenzophenon werden mit 31 Teilen Di- i-naphthyläthylendiamin und 3o Teilen Toluol zusammengeschmolzen. Zu der auf etwa 6o° abgekühlten Mischung setzt man 36 Teile Phosphoroxychloryd und rührt sie dann auf dem Wasserbade, bis sie fest wird. Man verrührt die Masse in iooo Teilen heißen Wassers und scheidet durch Zugabe von wenig Natriumchlorid den Farbstoff in kristallinischer Form aus. Er färbt Wolle und tannierte Baumwolle klar violett. Durch Sulfieren bei niedriger Temperatur entsteht ein blauvioletter Wollfarbstoff.Example. 54 parts of 4, 4'-Tetramethyldiaminobenzophenon are with 31 parts of di-i-naphthylethylenediamine and 3o parts of toluene melted together. 36 parts of phosphorus oxychloride are added to the mixture, which has been cooled to about 60 ° then stir it on the water bath until it solidifies. The mass is stirred in 10000 parts of hot water and separates by adding a little sodium chloride Dye in crystalline form. It dyes wool and tannic cotton clearly violet. Sulphurizing at low temperature produces a blue-violet wool dye.

4; 4'-Tetraäthyldiaminobenzophenon liefert beider Kondensation mit Di-i-naphthyläthylendiamin einen Farbstoff von ähnlichen Eigenschaften.4; 4'-Tetraäthyldiaminobenzophenon provides both condensation with Di-i-naphthylethylenediamine a dye with similar properties.
