Description
Verfahren zur Darstellung eines wasseruDiöslichen Azofarbstoffes. Gegenstand dieses Zusatzpatentes ist ein Verfahren zur Darstelluno- eines wa,sser- unlöslichen Azofarbstoffes, das dadurch ge kennzeichnet ist, dass man die Diazoverbin- dung von m-Chloranilin mit Terephtaloyl- bis <B>-</B> essigsäure <B>- 1 -</B> amino <B>- 3,
-</B> ühlor <B>-</B> 4<B>.</B> 6- diin,-thoxybenzol kuppelt. Die, Einwirkung der beiden Komponenten aufeinander kann auch in Gegenwart eines Substrates erfolgen.
Der in Substanz hergestellte Farbstoff bildet ein gelbes Pulver; die Färbungen be sitzen einen lebhaften gelben Farbton und sind sehr cut lichtecht.
<I>Beispiel:</I> <B>58,9</B> gr Terephtaloyl <B>-</B> bis<B>-</B> essigsäure <B>-</B> 1- amino <B>- 3 -</B> ehlor <B>-</B> 4<B>. 6 -</B> dimathcxybenzol werden in<B>100</B> cm' doppelt normaler -Natron lauge und Wasser heiss gelöst.
Diese Lösung lä,uft zu einer wie folgt bereiteten D#iazo- lösung: <B>25,6</B> gr m-Chlo#ranilin werden mit <B>52</B> cm' Salzsäure von 22' B6 und 14,4 gr Natriumnitrit unter Eiszusatz wie üblieh diazotiert und mit Natriumacetat auf Konoo- neutralität abgestumpft.
Die Farbstoffbildung ist nach mehrst-au- di-em Nachrühren beendet. Man saugt ab, wäscht gut mit Wasser und trocknet.
Man erhält ein gelbes Pulver. Die Dar- stellun,g des Farbstoffes kann auch in Gegen wart eines Substrates erfolgen. Wird der Farbstoff auf der Faser erzeugt, so erhält man einen sehr lichtechten, lebhaften gelben Farbton.
Process for the preparation of a water-soluble azo dye. The subject of this additional patent is a process for the preparation of a water-insoluble azo dye, which is characterized in that the diazo compound of m-chloroaniline with terephtaloyl- to <B> - </B> acetic acid <B> - 1 - </B> amino <B> - 3,
- </B> ühlor <B> - </B> 4 <B>. </B> 6- diine, -thoxybenzene couples. The action of the two components on one another can also take place in the presence of a substrate.
The dye produced in substance forms a yellow powder; the colors have a lively yellow shade and are very lightfast.
<I> Example: </I> <B> 58.9 </B> gr terephtaloyl <B> - </B> to <B> - </B> acetic acid <B> - </B> 1- amino <B> - 3 - </B> ehlor <B> - </B> 4 <B>. 6 - </B> dimethylbenzene are dissolved in <B> 100 </B> cm 'double normal caustic soda and hot water.
This solution leads to a diazo solution prepared as follows: <B> 25.6 </B> gr m-chloraniline are mixed with <B> 52 </B> cm 'hydrochloric acid of 22' B6 and 14.4 g sodium nitrite with the addition of ice, diazotized as usual and blunted with sodium acetate to neutrality.
The formation of the dyestuff has ended after several additional stirring times. It is suctioned off, washed well with water and dried.
A yellow powder is obtained. The presentation of the dye can also take place in the presence of a substrate. If the dye is produced on the fiber, a very lightfast, vivid yellow color is obtained.
