Description
Verfahren zur Herstellung eines Derivates der 4,4'-Diamino-stilben-disulfonsäure-(2,2'). Es wurde gefunden, dass man zu einem neuen Derivat der 4,4'-Diamino-stilben-disul- fonsäure-(2,2') gelangt, wenn man erfindungs gemäss 1 Mol Cy anurchlorid mit 1 Mol des Di- natriumsalzes der 4-[2-Ä.thylamino-4-(o-anisi- dino) -1, 3,5-triazyl-(6)-amino ] - 4'-amino-stilben- disulfonsäure-(2,2'),
1 Mol Methylamin und 1 Mol Äthanolamin umsetzt.
Das so erhaltene neue Natriumsalz der Formel 3s
EMI0001.0020
ist ein gelbliches, wasserlösliches Pulver und i kann zum optischen Bleichen von Cellulose- fasern verwendet werden.
<I>Beispiel:</I> Durch Kondensation von 1 Mol Cyanur- ehlorid mit 1 Mol 4'-Nitro-4-amino-stilben-di- sulfonsäure-(2,2'), 1 Mol Äthylamin und 1 Mol o-Anisidin und anschliessende Reduktion wird das Dinatriumsalz der 4-[2-Äthvjamino-4-(o- anisidino) -1,3,5 - triazyl - (6 )
-amino ] -4'- amino- stilben-disulfonsäure-(2,2') hergestellt. Dieses s wird mit 1 Mol Cyanurchlorid, 1 Mol Methyl- amin und 1.
Mol Äthanolamin zum Dinatrium- salz der 4-[2-Ät.hylamino-4-(o-anisidino)-1,3,5- triazyl-(6)-amino ] -4'- [ 2-methy 1 amino-4- (ss-oxy- äthyIamino) -1,3, 5 - triazyl- (6) - amino] -stilben- disulfonsäure-(2,2') umgesetzt.
Es ist. ein gelb- liches Pulver, dessen wässerige Lösungen auf ein Cellulosematerial aufgebracht, dieses im ultravioletten Licht bläulich aufleuchten las sen.
Process for the preparation of a derivative of 4,4'-diamino-stilbene-disulfonic acid- (2,2 '). It has been found that a new derivative of 4,4'-diamino-stilbene-disulphonic acid- (2,2 ') is obtained if, according to the invention, 1 mol of cyano chloride with 1 mol of the disodium salt of 4- [2-Ä.thylamino-4- (o-anisidino) -1, 3,5-triazyl- (6) -amino] -4'-amino-stilbene-disulfonic acid- (2,2 '),
Reacts 1 mole of methylamine and 1 mole of ethanolamine.
The new sodium salt of formula 3s thus obtained
EMI0001.0020
is a yellowish, water-soluble powder and i can be used for the optical bleaching of cellulose fibers.
<I> Example: </I> By condensation of 1 mole of cyanuric chloride with 1 mole of 4'-nitro-4-amino-stilbene-disulfonic acid- (2.2 '), 1 mole of ethylamine and 1 mole of o- Anisidine and subsequent reduction is the disodium salt of 4- [2-Äthvjamino-4- (o- anisidino) -1,3,5 - triazyl - (6)
-amino] -4'-aminothilbene-disulfonic acid- (2,2 '). This s is with 1 mol of cyanuric chloride, 1 mol of methylamine and 1.
Moles of ethanolamine to the disodium salt of 4- [2-ethylamino-4- (o-anisidino) -1,3,5-triazyl- (6) -amino] -4'- [2-methy 1 amino-4 - (s-oxy-äthyIamino) -1,3,5-triazyl- (6) -amino] -stilbene-disulfonic acid- (2,2 ') implemented.
It is. a yellowish powder, the aqueous solutions of which are applied to a cellulose material, causing it to glow bluish in ultraviolet light.
