Description
Verfahren zur Herstellung eines Farbstoffes. Im Hauptpatent Nr. 178550 ist ein Ver fahren zur Herstellung eines Farbstoffes der Triarylmethanreihe angegeben, bei dem 1 Mol ss.ss'-Di-(N-methyl-a-phenylindolyl)-keton mit 1 bis 1,2 Mol 4-Methyl-3'-äthoxydiphenyl- amin mittels Phosphoroxychlorid kondensiert wird, worauf der erhaltene basische Farb stoff so lange mit einem sulfonierend wir kenden Mittel behandelt wird, bis zwei Sul- fonsäuregruppen eingetreten sind.
Es wurde nun gefunden, dass man einen ebenfalls wertvollen Farbstoff erhält, wenn man 1 Mol ss,ss'-Di-(N-methyl-a-phenylindo- lyl)-keton mit 1 bis 1,2 Mol 4-Äthoxydiphe- nylamin mittels Phosphoroxychlorid kon densiert und den erhaltenen basischen Farb stoff so lange mit einem sulfonierend wir kenden Mittel behandelt, bis zwei Sulfon- säuregruppen eingetreten sind.
Hierbei rea giert das angewandte Keton zunächst mit dem Phosphoroxychlorid unter Bildung eines Zwischenproduktes, das sich mit dem an- gewandten Amin umsetzt. Man kann ent weder so arbeiten, dass man das Keton, das Phosphoroxychlorid und das Amin gleich zeitig aufeinander einwirken lässt, oder so, dass man 1 Mol ss,ss'-Di-(N-methyl-a-phenyl- indolyl)-keton zunächst durch Behandeln mit Phosphoroxychlorid in das erwähnte Zwi schenprodukt überführt, worauf dieses mit 1 bis 1,
2 22o1 4-Äthoxydiphenylamin zum basischen Farbstoff umgesetzt wird, der so dann sulfoniert wird.
Der neue Farbstoff liefert auf Wolle und Seide gedeckte blaue Töne von sehr guter Lichtechtheit.
Beispiel <I>1:</I> Man kondensiert 88 Teile ss,ss'-Di-(N-me- thyl-a-phenylindolyl)-keton in 44 Teilen To luol mit 47 Teilen 4-Äthoxydiphenylamin mittels 33 Teilen Phosphoroxychlorid zum basischen Farbstoff und arbeitet wie üblich auf. Der gereinigte und getrocknete basische Farbstoff wird sodann in 90%ige Schwefel säure eingetragen und durch Zugabe von Schwefelsäuremonohydrat zur Disulfonsäure sulfoniert. Klan arbeitet das Reaktions gemisch in der üblichen Weise auf.
<I>Beispiel 2:</I> 88 Teile ss,ss'-Di-(N-methyl-a-phenylindo- lyl)-keton werden in 70 Teilen Tetrachlor- äthan mittels 36 Teilen Phosphoroxychlorid umgesetzt, worauf das erhaltene Zwischen produkt anschliessend mit 47 Teilen 4- Äthoxydiphenylamin zum basischen Farb stoff kondensiert wird. Der gereinigte und getrocknete basische Farbstoff wird sodann in 90%ige Schwefelsäure eingetragen und durch Zugabe von Schwefelsäuremonohydrat zur Disulfonsäure sulfoniert. Man arbeitet das Reaktionsgemisch in der üblichen Weise auf.
Process for the preparation of a dye. In the main patent no. 178550 a process is given for the production of a dye of the triarylmethane series, in which 1 mol of ss.ss'-di (N-methyl-a-phenylindolyl) ketone with 1 to 1.2 mol of 4-methyl 3'-ethoxydiphenylamine is condensed by means of phosphorus oxychloride, whereupon the basic dye obtained is treated with a sulfonating agent until two sulfonic acid groups have occurred.
It has now been found that an equally valuable dye is obtained if 1 mol of ss, ss'-di- (N-methyl-a-phenylindolyl) ketone with 1 to 1.2 mol of 4-ethoxydiphenylamine is used Phosphorus oxychloride condenses and the basic dye obtained is treated with a sulfonating agent until two sulfonic acid groups have occurred.
The ketone used here initially reacts with the phosphorus oxychloride to form an intermediate product which reacts with the amine used. One can either work in such a way that the ketone, the phosphorus oxychloride and the amine are allowed to act on one another at the same time, or in such a way that 1 mol of ss, ss'-di- (N-methyl-a-phenylindolyl) ketone is used first converted into the mentioned intermediate product by treatment with phosphorus oxychloride, whereupon this with 1 to 1
2 22o1 4-ethoxydiphenylamine is converted to the basic dye, which is then sulfonated.
The new dye provides muted blue tones with very good lightfastness on wool and silk.
Example <I> 1: </I> 88 parts of ss, ss'-di (N-methyl-a-phenylindolyl) ketone in 44 parts of toluene with 47 parts of 4-ethoxydiphenylamine are condensed using 33 parts of phosphorus oxychloride basic dye and works on as usual. The purified and dried basic dye is then introduced into 90% strength sulfuric acid and sulfonated to disulfonic acid by adding sulfuric acid monohydrate. Klan processes the reaction mixture in the usual way.
Example 2: 88 parts of ss, ss'-di (N-methyl-a-phenylindolyl) ketone are reacted in 70 parts of tetrachloroethane using 36 parts of phosphorus oxychloride, whereupon the intermediate product obtained is then condensed with 47 parts of 4-ethoxydiphenylamine to form the basic dye. The cleaned and dried basic dye is then introduced into 90% sulfuric acid and sulfonated to disulfonic acid by adding sulfuric acid monohydrate. The reaction mixture is worked up in the usual manner.
