Description

Verfahren zur Herstellung von Azofarbstoffen Gegenstand des Patents 658 124 ist ein Ver- fahren zur Herstellung von insbesondere zum Tärben von Cellulosees.tern geeigneten Azo- farbstoffen., demzufolge dianotiertes 6-Brom- oder 6-Chlor-2, 4-dinitro-i-aminobenzol und i-y-Methoxy-ß-oxypropylaminonaphthalin ge- kuppelt werden. Wie nun weiter gefunden wurde, erhält man Azofarbstoffe von ähnlichen Farbtönen, wenn man die Diazoverbindungen aus 6-Brom- oder 6-Chlor-2, 4-dinitro-i-aininobenzol mit i-3= @- Di.oxypropylaminonaphthjalin kuppelt. Die so erhältlichen Azofarbstoffe liefern gleichfallsa auf Acetatkunstseide w eißätzbäre, klare Blautöne. Vor den. bekannten Azofarb- stoffen aus diazotilertem 6 - Methyl- oder 6-Methoxy-2, 4-dinitro- i-;aminobenzol und i-Ox- äthylamino- oder i-y-Chlor-rD-oxypropylamino- naphtbalin und dem bekannten Azofarbstoff aus dianotiertem 6-Brom-2, 4-dirutro-i-amino- ben.zol und i-Oxäthylaminonaphthalin zeich- nen sich die neuen Farbstoffe teils durch bes- seres Ziehvermögen, teils durch erhöhte Al- kali- oder Säure- oder Chlorechtheit aus. Beispiel i 26,2 Teile 6-Brom-2,4-dinitro-i-aminobenzol werden in bekannter Weise dianotiert und mit 22 Teilen i-13=;-Dioxypropylamixronaphthalin gekuppelt. Der erhaltene Azofarbstoff färbt Acetatkunstseide in rein blauen Tönen. Beispiel 2 2i,8Teilt 6-Chlor-2,4,-dinitro-i-,aminobenzol werden dianotiert und mit 22 Teilen i-(3-y-Di- oxypropylameonaphtbialin gekuppelt. Der er- haltene Azofarbstoff färbt Acetatkunstseide rein blau. Process for the production of azo dyes The subject of the patent 658 124 is a drive to the production of in particular to Tinting of cellulose, internally suitable azo dyes., consequently dianotized 6-bromine or 6-chloro-2, 4-dinitro-i-aminobenzene and iy-methoxy-ß-oxypropylaminonaphthalene ge be coupled. As has now been found further, one obtains Azo dyes of similar hues, though the diazo compounds from 6-bromine or 6-chloro-2, 4-dinitro-i-aininobenzene with i-3 = @ - Di.oxypropylaminonaphthjalin couples. The azo dyes obtainable in this way provide also a white etched bear on acetate silk, clear blue tones. Before. known azo color substances made of diazotized 6 - methyl or 6-methoxy-2, 4-dinitro- i-; aminobenzene and i-ox- ethylamino- or iy-chloro-rD-oxypropylamino- naphtbalin and the well-known azo dye from dianotized 6-bromo-2, 4-dirutro-i-amino- ben.zol and i-oxethylaminonaphthalene some of the new dyes can be drawability, partly due to increased Al- Potassium, acid or chlorine fastness. Example i 26.2 parts of 6-bromo-2,4-dinitro-i-aminobenzene are dianotated in a known way and with 22 parts i-13 =; - Dioxypropylamixronaphthalene coupled. The azo dye obtained stains Acetate artificial silk in pure blue tones. Example 2 2i, 8 parts 6-chloro-2,4, -dinitro-i-, aminobenzene are dianotized and mixed with 22 parts i- (3-y-Di- oxypropylameonaphtbialin coupled. The he Holding azo dye dyes acetate rayon pure blue.
