Description
Zusatzpatent zum Hauptpatent Nr. 238845. Verfahren zur Herstellung eines Polyazofarbstoffese Es wurde gefunden, dass man einen neuen Polyazofarbstoff erhält, wenn man 1 Mol 4.4'-Diaminostilben-2.2'-disulfonsäure, 2 Mol Cyanurchlorid mit 3 Mol 4'-Amino-1.1'-azo- benzol-4-oxy-3-carbonsäure und 1 Mol 4 Amino-1.1'-azobenzol-4'rsulfonsäure derart aufeinander einwirken lässt,
dass 2 Halogen atome des einen Cyanurchloridmoleküls und 1 Halogenatom des andern Cyanurchlorid- moleküls sich mit der Aminogruppe der 4'- Amino -1.1'- azobenzol - 4- oxy- 3-carbonsäure, ferner das zweite Halogenatom des zweiten Cyanurchloridmoleküls sich mit der Amino- gxuppe der 4-Amino-1.1'-azobenzol-4'-sulfon- säure umsetzen,
und dass schliesslich jeweils das dritte Halogenatom der beiden Cyanur- chloridmoleküle sich jeweils mit einer Amino- gruppe der 4.4'-Diaminostilben-2.2'-disulfon- säure umsetzt.
Der neue Farbstoff stellt getrocknet ein gelbbraunes Pulver dar, welches sich in Was ser mit gelbbrauner, in verdünnter Natrium hydrogydlösung oder in konzentrierter Schwefelsäure mit brauner Farbe löst und welches die vegetabile Faser sowie Kunst seide aus regenerierter Cellulose in gelben Tönen anfärbt, welche durch Nachbehandeln mit kupferabgebenden Mitteln im Färbebad hervorragend waschecht werden.
Beispiel: Man stellt in an sich bekannter Weise eine feine Suspension von 3e6,8 Teilen Cyanurchlo- rid in 400 Teilen Eiswasser dar. 7u dieser ,Suspension gibt man eine Lösung von 37 Tei len 4.4'-Diaminostilben-21.2'-disulfonsäure (als Dinatriumsalz) in 600 Teilen Wasser zu. Das Kondensationsprodukt aus 1 Äquivalent Di- aminostilbendisulfonsäure und 2 Äquivalen ten Cyanurchlorid fällt in Form blassgelber gallertiger Suspension zum grossen Teil aus.
Man rührt noch zirka eine Stunde bei 0-5 unter gleichzeitigem Zutropfen einer Lösung von 15 Teilen Natriumcarbonat in 150 Teilen Wasser. Alsdann gibt man eine warme Lö sung des Natriumsalzes von 87,1 Teilen 4'-Amino -1.1' - azobenzol-4-oxy-3-carbonsäure und 2e7,7 Teile 4-Amino-1.1'-azobenzol-4'-sul- fonsäure in zirka 1500 Teilen Wasser zu.
Man erwärmt das Gemisch auf etwa 40-45 , hält diese Temperatur 2 Stunden, stumpft die freiwerdende Säure während ihrer Entste hung mit Natriumcarbonatlösung ab, steigert alsdann die Temperatur auf zirka 95 und hält diese Temperatur ? Stunden unter weite rer Zugabe von ?? Teilen Natriumcarbonat. Man lässt erkalten und salzt den Farbstoff der mutmasslichen Formel
EMI0002.0005
durch Zugabe von 50 Teilen Kochsalz aus, lässt auf zirka 50 erkalten und nutscht den Farbstoff ab.
Additional patent to main patent no. 238845. Process for the production of a polyazo dye It has been found that a new polyazo dye is obtained if 1 mole of 4,4'-diaminostilbene-2.2'-disulfonic acid, 2 moles of cyanuric chloride with 3 moles of 4'-amino-1.1 ' -azobenzene-4-oxy-3-carboxylic acid and 1 mol of 4-amino-1,1'-azobenzene-4'rsulfonic acid can act on one another in such a way that
that 2 halogen atoms of one cyanuric chloride molecule and 1 halogen atom of the other cyanuric chloride molecule with the amino group of the 4'-amino -1.1'-azobenzene-4-oxy-3-carboxylic acid, furthermore the second halogen atom of the second cyanuric chloride molecule with the amino convert the group of 4-amino-1,1'-azobenzene-4'-sulfonic acid,
and that finally the third halogen atom of each of the two cyanuric chloride molecules reacts with an amino group of 4.4'-diaminostilbene-2.2'-disulfonic acid.
The new dye is a yellow-brown powder when dried, which dissolves in water with yellow-brown, in dilute sodium hydrogyd solution or in concentrated sulfuric acid with a brown color and which stains the vegetable fibers and synthetic silk made from regenerated cellulose in yellow tones, which are then treated with copper-releasing agents become extremely washable in the dye bath.
Example: A fine suspension of 36.8 parts of cyanuric chloride in 400 parts of ice water is prepared in a manner known per se. A solution of 37 parts of 4.4'-diaminostilbene-21.2'-disulfonic acid (as disodium salt) is added to this suspension ) in 600 parts of water. The condensation product of 1 equivalent of diaminostilbene disulfonic acid and 2 equivalents of cyanuric chloride precipitates for the most part in the form of pale yellow gelatinous suspension.
The mixture is stirred for about an hour at 0-5 with simultaneous dropwise addition of a solution of 15 parts of sodium carbonate in 150 parts of water. Then a warm solution of the sodium salt of 87.1 parts of 4'-amino -1.1 '- azobenzene-4-oxy-3-carboxylic acid and 2e7.7 parts of 4-amino-1.1'-azobenzene-4'-sul- fonsäure in about 1500 parts of water.
The mixture is heated to about 40-45, this temperature is maintained for 2 hours, the acid released is blunted with sodium carbonate solution while it is being formed, then the temperature is increased to about 95 and this temperature is maintained Hours with further addition of ?? Share sodium carbonate. Allow to cool and salt the dye of the presumed formula
EMI0002.0005
by adding 50 parts of table salt, allowing to cool to about 50 and sucking off the dye.
