Description
Verfahren zur Herstellung eines Azofarbstoffes. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines Azofarbstoffes, dadurch gekennzeichnet, dass man die Diazo- verbindung von 1 -Amino-4-N-cyklohexyl- caprinylaminobenzol mit 1-Benzoylamino-8- oxynaphthalin-4.6-disulfonsäure vereinigt.
Der so erhaltene Farbstoff ist ein -rotes Pulver und färbt Wolle aus neutralem oder saurem Bade in blauroten Tönen von vor züglichen Echtheitseigenschaften, insbeson dere guter Wasch-, Walk-, Schweiss-, See wasser- und Lichtechtheit.
<I>Beispiel:</I> 34,4 Teile 1- Amino - 4 - N - Cyklohexyl- oaprinylaminobenzol werden diazotiert. Die erhaltene Diazoverbindung vereinigt man mit einer sodaalkalischen Lösung von 43 Teilen 1-Benzoylamino -8 - oxynaphthalin -4.6 - disul- fonsäure. Der gebildete Farbstoff wird ab geschieden und getrocknet.
Process for the preparation of an azo dye. The present patent relates to a process for the preparation of an azo dye, characterized in that the diazo compound of 1-amino-4-N-cyclohexyl-caprinylaminobenzene is combined with 1-benzoylamino-8-oxynaphthalene-4,6-disulfonic acid.
The dye thus obtained is a red powder and dyes wool from a neutral or acidic bath in blue-red tones with excellent fastness properties, in particular good fastness to washing, milling, perspiration, sea water and light.
<I> Example: </I> 34.4 parts of 1-amino-4-N-cyclohexyl-oaprinylaminobenzene are diazotized. The diazo compound obtained is combined with a soda-alkaline solution of 43 parts of 1-benzoylamino -8-oxynaphthalene-4.6-disulphonic acid. The dye formed is separated off and dried.
