Description
Verfahren zur Herstellung eines Derivates der 4,4'-Diaminostilben-disulfonsäure-(2,2'). Es wurde gefunden, dass man zu einem neuen Derivat der 4,4'-Diaminostilben-disul- fonsäure-(2,2') gelangt, wenn man 1 11o1 des Dinatriumsalzes der -1,4'-Bis-[2-äthylamino-4- ehlor-1,3,5-triazyl- <B>(6)</B> -amino] -stilben-disulfon- Das so erhaltene Natriumsalz der Formel.
EMI0001.0012
ist in Wasser löslich und kann zum optischen Bleiehen von Baumwolle verwendet werden.
<I>Beispiel:</I> Zn einer Lösung von 72,7 Teilen des Di- natriumsalzes der 4,4'-Bis-[2-äthylamino-4-- ehlor-1,3,5-triazyl@ (6) -amino]-st.ilben-disulfon- säure-(2,2') (hergestellt durch Kondensation von 2 Mol Cyanurchlorid mit.
1 Mol 4,4'-Di- aminostirlben-disulfonsäure-(2,2') und 211o1 Monoäthylamin), in 700 Teilen Wasser wer den bei 35 bis 40 unter Rühren -12 Teile Anilin zugefügt.. Anschliessend steigert man die Temperatur des Reaktionsgemisches in nerhalb 2 Stunden auf 80 und rührt während 8 Stunden. bei 80 bis 90 . Hierauf fügt man Natriumearbonatlösung bis zur deutlich alka- säure-(2,2') mit 2 Mol Anilin umsetzt. Die Umsetzung kann z.
B. in der Weise erfolgen, dass man eine wässerige Lösung des genannten Dinatriumsalzes bei 40 bis 90 mit 2 1To1 Anilin reamieren lässt. Tischen Reaktion zu, lässt .das Reaktionsge misch. auf 15 bis 20 abkühlen und setzt Na triumchlorid zu.
Das abgeschiedene Dinatrium- salz der 4,4'-Bis-[2-äthylamino-4-anilino-1,3,5- triazyl- (6) -amino ] -stilben-disulf onsäure- (2,2') wird abfiltriert, mit Natriumehloridlösung ge waschen und getrocknet.. Man erhält. das neue Produkt als hellgelbes, wasserlösliches Pulver.
Baumwolle, die mit einer wässerigen Lö sung des Pulvers behandelt wurde, erscheint weisser als Baumwolle, die ohne den Zusatz dieses Produktes behandelt wurde.
Process for the preparation of a derivative of 4,4'-diaminostilbene-disulfonic acid- (2,2 '). It has been found that a new derivative of 4,4'-diaminostilbene-disulphonic acid- (2,2 ') is obtained if 1 11o1 of the disodium salt of -1,4'-bis [2-ethylamino- 4- chloro-1,3,5-triazyl- <B> (6) </B> -amino] -stilbene-disulfone- The thus obtained sodium salt of the formula.
EMI0001.0012
is soluble in water and can be used for the optical bleeding of cotton.
<I> Example: </I> Zn a solution of 72.7 parts of the disodium salt of 4,4'-bis [2-ethylamino-4-chloro-1,3,5-triazyl @ (6) -amino] -st.ilbene-disulfonic acid- (2,2 ') (produced by condensation of 2 moles of cyanuric chloride with.
1 mol of 4,4'-di-aminostirlben-disulfonic acid- (2,2 ') and 211o1 monoethylamine), in 700 parts of water, -12 parts of aniline are added at 35 to 40 with stirring. The temperature of the reaction mixture is then increased to 80 within 2 hours and stir for 8 hours. at 80 to 90. Sodium carbonate solution is then added until the alkali acid (2.2 ') is clearly reacted with 2 moles of aniline. The implementation can e.g.
B. be carried out in such a way that an aqueous solution of said disodium salt can be reamed at 40 to 90 with 2 1To1 aniline. If a reaction allows, the reaction mixture. cool to 15 to 20 and add sodium chloride.
The separated disodium salt of 4,4'-bis [2-ethylamino-4-anilino-1,3,5-triazyl- (6) -amino] -stilbene-disulfonic acid- (2,2 ') is filtered off , washed with sodium chloride solution and dried .. One obtains. the new product as a light yellow, water-soluble powder.
Cotton that has been treated with an aqueous solution of the powder appears whiter than cotton that has been treated without the addition of this product.
