Description
Verfahren zur Herstellung eines ehromierbaren Farbstoffes. (Tegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung eines ehromier- baren Farbstoffes. Das Verfahren ist dadurch gekennzeielinet, dass man diazotiertes 2-Amino- 1- oxy - Benzol - 4- inethylsulfon mit 1- Carbo- methoxyaniino-7-oxy-naphtlialin vereinigt.
Der Chromkomplex des erhaltenen neuen Farbstoffes stellt ein schwarzblaues Pulver dar, das Wolle aus neutralem oder schwach organisch saurein Bade in grauen Tönen von hervorragender Lichtechtheit und sehr guten Nasseehtheiten färbt.
<I>Beispiel:</I> 17,7 Teile 2-Amino-l-oxy-benzol-4-methyl- sulfi i werden in 150 Teilen heissem Wasser mit 17 Teilen konzentrierter Salzsäure gelöst, auf<B>50</B> abgekühlt und mit einer Lösung von <B>6,9</B> Teilen Natriumnitrit diazotiert. Die Diazo- niumverbindung fällt dabei teilweise in Form lehmgelber Kristalle aus.
Durch Zugabe von Natriumbicarbonat stellt man neutral und giesst die Aufschlämmung in eine Lösung von 22,8 Teilen 1-Carbomethoxyamino-7-oxy-naph- thalin, 4,8 Teilen Natriumhydroxyd, 12 Teilen wasserfreier Soda und 15 Teilen Pyridin in <B>100</B> Teilen Wasser. Nach Beendigung der Parb- stoffbildung isoliert man den Farbstoff bei 700 durch Versetzen mit Kochsalz.
Der Chromkomplex des Farbstoffes kann erhalten werden, indem man in 500 Teilen Wasser finit 110 Teilen einer Lösung von eliromsalicylsauremAmmonium (entsprechend 4,2 Teilen Chromoxyd) unter Rüekfluss zum Sieden erhitzt, bis die Komplexbildung be endet ist.. Der Chromkomplex scheidet sich dabei fast vollständig aus. Fr wird abfiltriert, getrocknet und mit 20% seines Gewichtes an wasserfreier Soda vermischt. Fr stellt ein schwarzblaues Pulver dar, das glatt wasser löslich ist.
Process for the production of an honorable dye. (The subject of the present patent is a process for the production of an honorable dye. The process is characterized in that diazotized 2-amino-1-oxy-benzene-4-ynethylsulfone is combined with 1-carbo-methoxyaniino-7-oxy-naphthlialine .
The chromium complex of the new dye obtained is a black-blue powder that dyes wool from a neutral or slightly organic acidic bath in gray shades of excellent lightfastness and very good wetness properties.
<I> Example: </I> 17.7 parts of 2-amino-1-oxy-benzene-4-methylsulfi i are dissolved in 150 parts of hot water with 17 parts of concentrated hydrochloric acid, to <B> 50 </ B > cooled and diazotized with a solution of <B> 6.9 </B> parts of sodium nitrite. The diazonium compound partially precipitates in the form of clay-yellow crystals.
The suspension is neutralized by adding sodium bicarbonate, and the suspension is poured into a solution of 22.8 parts of 1-carbomethoxyamino-7-oxynaphthalene, 4.8 parts of sodium hydroxide, 12 parts of anhydrous soda and 15 parts of pyridine in 100 </B> Share water. After the formation of paraffin has ended, the dye is isolated at 700 by adding sodium chloride.
The chromium complex of the dye can be obtained by refluxing 110 parts of a solution of eliromsalicylic acid ammonium (equivalent to 4.2 parts of chromium oxide) in 500 parts of water until the complex formation is over. The chromium complex separates almost completely out. Fr is filtered off, dried and mixed with 20% of its weight of anhydrous soda. Fr represents a black-blue powder that is readily soluble in water.
