Verfahren zur Herstellung eines sauren Monoazofarbstoffes.
EMI0001.0003
f <SEP> z'erreiistaricl <SEP> des <SEP> vorliegenden <SEP> Patentes <SEP> ist
<tb> ein <SEP> Verfahren <SEP> zur <SEP> Verstellung <SEP> eines <SEP> sauren
<tb> Monoazofarbstoffes, <SEP> welches <SEP> darin <SEP> besteht,
<tb> dass <SEP> nian <SEP> 1 <SEP> lIol <SEP> der <SEP> Diazoverbindung <SEP> aus <SEP> 2 Aniino-5,6,7,ä-tetrahy <SEP> dronaphtlialin- <SEP> 3 <SEP> -sulfon sä <SEP> ure <SEP> mit <SEP> 1 <SEP> llol <SEP> 1-Oxy-6-deca.noylaniinona.ph tlialin-3-sulfonsäure <SEP> kuppelt.
<tb>
Ini <SEP> nachfolgenden <SEP> Beispiel <SEP> bedeuten <SEP> die
<tb> 'feile <SEP> (iewielitsteile. Beispiel: :.'2,7 Teile 2-Amino-5,6,7,8-tetralivdronapli- t li < ilin-3-sulfonsäurc werden in 100 Teilen l@alteni Wasser und 100 Teilen normaler Na- ti-iiunliycli>oiydlösung gelöst und mit einer Lösun o- von 7 Teilen Natriunmitrit in 50 Tei len Wasser versetzt.
Durch Zugabe von Eis wird die Temperatur auf 5 bis 10 gebracht. plan giesst hierauf unter Rühren 30 Teile kon zentrierte Salzsäure auf einmal zu und rührt bei 10 bis 15 , bis die salpetrige Säure ver- sehwunden ist.. Hierbei scheidet sich die Di- azoverbindun- zum Teil aus.
Die Suspension der Dia.zoverbindung wird iiiii, der wässrigen Suspension von 39,2 Teilen 1- Oxy- 6 - deeanoylitniilionaphtlialin - i - sulfon- säure in 1.500 Teilen Wasser in Cregenwa.rt von übersehüssigem N atriumbiearbonat bei 10-15 vereinigt.
Nach beendeter Kupplung wird der neue Farbstoff ausgesalzen, abfiltriert und getrock- net. Er ist ein orangefarbenes Pulver, das sich in Wasser mit oranger Farbe löst und. Wolle, Seide und Polvainidfasern aus schwach saurem Bad in lebhaften rotstichig orangen Tönen von guter Wasch- und Schweissechtheit und sehr guter Lichtechtheit färbt.
Process for the preparation of an acidic monoazo dye.
EMI0001.0003
f <SEP> z'erreiistaricl <SEP> of the <SEP> present <SEP> patent <SEP> is
<tb> a <SEP> method <SEP> for <SEP> adjustment <SEP> of a <SEP> acid
<tb> monoazo dye, <SEP> which <SEP> consists of <SEP>,
<tb> that <SEP> nian <SEP> 1 <SEP> lIol <SEP> of the <SEP> diazo compound <SEP> from <SEP> 2 aniino-5,6,7, ä-tetrahy <SEP> dronaphtlialin- <SEP > 3 <SEP> -sulfon sä <SEP> ure <SEP> with <SEP> 1 <SEP> llol <SEP> 1-Oxy-6-deca.noylaniinona.ph tlialin-3-sulfonic acid <SEP> couples.
<tb>
In <SEP> the following <SEP> example <SEP> mean <SEP> the
<tb> 'file <SEP> (iewielitsteile. Example:.' 2.7 parts of 2-amino-5,6,7,8-tetralivdronapli- t li <ilin-3-sulfonic acid are in 100 parts of l @ alteni water and 100 parts of normal sodium chloride solution and a solution of 7 parts of sodium mitrite in 50 parts of water is added.
The temperature is brought to 5 to 10 by adding ice. Plan then pour in 30 parts of concentrated hydrochloric acid all at once with stirring and stir at 10 to 15 until the nitrous acid is gone. The diazo compound is partially eliminated.
The suspension of the diazo compound is iiiii, the aqueous suspension of 39.2 parts of 1-oxy-6-deeanoylitniilionaphthlialin-1-sulfonic acid, combined in 1,500 parts of water in Cregenwa.rt of excess sodium carbonate at 10-15.
When the coupling is complete, the new dye is salted out, filtered off and dried. It is an orange powder that dissolves in water with an orange color and. Wool, silk and polvainide fibers from a weakly acidic bath dyes in lively reddish orange tones of good fastness to washing and perspiration and very good fastness to light.
