Description
Verfahren zur Herstellung einer wasserlöslichen, organischen Stickstoffverhindung. Es wurde gefunden, dass man wertvolle wasserlösliche, organische Stickstoffverbin- dungen herstellen kann, wenn man Verbin dungen der Formel
EMI0001.0006
worin R1 ein Wasserstoffatom oder ein nied- rigmolekularer organischer Rest, R" ein mit lt', identischer oder ein gegebenenfalls sub- stituierter Aminoäthyl- bzw.
Aminopropyl- rest, R" ein gegebenenfalls substituierter Äthylen- oder Propylenrest und R, Wasser stoff oder einer der Reste ist, wie sie unter P., und R:: beschrieben sind, und Cyanamid, dessen Polymeren oder dessen Derivaten in Abwesenheit von Wasser, gegebenenfalls in Anwesenheit von nicht wässerigen Lösungs mitteln, bei erhöhter Temperatur unter Ab spaltung von Ammoniak aufeinander einwir- hen lässt.
Geeignete Verbindungen der Formel
EMI0001.0028
sind zum Beispiel Diäthylentriamin, TriätIly- lentetramin bzw. höhenmolekulare Polyäthy- lenpolya,mine, Polypropylenpolyamine, Di- ("oxypropylen)-triamin bzw. höhenmolekulare 1'oly(ogy-propylen)-polyamine.
Die Endprodukte sind basische Sirupöse bis dicke, fast farblose Flüssigkeiten oder feste Stoffe, die mit Hilfe organischer oder anorganischer Säuren in Salze überführt wer den können.
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer wasserlösli chen organischen Stickstoffverbindung, wel ches dadurch gekennzeichnet ist, dass man Triäthylentetramin und Dicyandiamid in Abwesenheit von Wasser bei erhöhter Tem peratur unter Abspaltung von Ammoniak aufeinander einwirken lässt.
Das Endprodukt ist eine basische, schwach gelb gefärbte, pulverisierbare, wasserlösliche .Hasse, die mit Hilfe geeigneter organischer oder anorganischer Säuren in wasserlösliche Salze übergeführt werden kann. Das basische Produkt wie auch dessen wasserlösliche Salze eignen sich als: solche oder zusammen mit wasserlöslichen Verbindungen der mehr wertigen Metalle wie Kupfer zur Verbesserung der Echtheitseigenschaften von Färbungen mit Substantiven Farbstoffen, zur Herstel lung von Pigmenten oder zur Animalisierung zellulosischer Fasern.
Sie besitzen ausserdem die Eigenschaft, saure Farbstoffe aus ihren wässerigen Lösungen zu fällen.
Beispiel: In einem mit kurzem Rückflusskühler werden 146 g Triäthylen- tetramin Kp. 270 bis 271 C und 84 g Dicyan- diamid eingetragen und die Temperatur vor erst auf 100 bis 110 C erhöht, wobei Am moniakabspaltung eintritt. Bei 110 C wird die Masse klar, und die, Temperatur wird nach Massgabe der Reaktion langsam auf 140 C gesteigert und so gehalten.
Nach 14 bis 16 Stunden wird die Masse herausgenom men, gekühlt und pulverisiert. Sie kann als solche oder als neutrales Salz gegebenenfalls mit Kupfersalzen zur Verbesserung der Echtheit von Färbungen mit substantiven Farbstoffen verwendet werden.
Das nach dem Beispiel hergestellte Kon densationsprodukt kann wie folgt in Konzen- trationen von 0,1 bis 2,0 g/Liter zur Verbes serung der Echtheiten von Färbungen mit substantiven Farbstoffen verwendet werden, wobei man sowohl vom Kondensationspro- dukt selbst wie auch von .seinen wasserlösli chen Salzen oder Komplexen mit mehrwerti gen Metallen ausgehen kann:
In. eine Lösung von 0,3 g des im Beispiel beschriebenen Kondensationsproduktes pro Liter wird bei einem Flottenverhältnis von zum Beispiel 1- : 30 eine 2 %ige Ausfärbung des blauen substantiven Farbstoffes Nr. 617 Schultz, Farbstofftabellen, Bd. I, Ausg.1931, auf Viskose eingebracht.
Die Färbung wird darin unter öfterem Umziehen bei Tempera turen zwischen 20 bis 100 C während 5 bis 20 Minuten behandelt. Das nachbehandelte Stück kann mit oder ohne Zwischenspülung abzentrifugiert und getrocknet werden. Eine Nachbehandlung bei erhöhter Temperatur verbessert in gewissen Fällen die Waschecht heit von Färbungen mit substantiven Farb stoffen noch weitergehend.
Die heisse Trock nung hingegen ist keineswegs, notwendig, in dem die noch nassen, direkt abgeschleuderten Stücke auch ohne Zwischentrocknung in al kalischen Waschflotten eine ausgezeichnete Echtheit aufweisen.
Es können auch andere substantive Fär bungen, z. B. .solche mit dem Schwarz Nr.<B>671</B> und Blau Nr. 513 Schultz, Färbstofftabellen, Bd.I, Ausgabe 1931, mit obigen Kondensa tionsprodukten verbessert werden.
Process for the production of a water-soluble, organic nitrogen compound. It has been found that valuable water-soluble, organic nitrogen compounds can be produced by using compounds of the formula
EMI0001.0006
where R1 is a hydrogen atom or a low molecular weight organic radical, R "is an aminoethyl- or optionally substituted aminoethyl- or optionally substituted one with lt '.
Aminopropyl radical, R "is an optionally substituted ethylene or propylene radical and R is hydrogen or one of the radicals as described under P., and R :: and cyanamide, its polymers or its derivatives in the absence of water, optionally in the presence of non-aqueous solvents, can be stirred into one another at an elevated temperature with elimination of ammonia.
Suitable compounds of the formula
EMI0001.0028
are, for example, diethylenetriamine, triethyl tetramine or high molecular weight polyethylene polyamines, mines, polypropylene polyamines, di ("oxypropylene) triamine or high molecular weight poly (ogy propylene) polyamines.
The end products range from basic syrup to thick, almost colorless liquids or solid substances that can be converted into salts with the help of organic or inorganic acids.
The present invention relates to a process for the production of a water-soluble organic nitrogen compound, which is characterized in that triethylenetetramine and dicyandiamide are allowed to act on one another in the absence of water at an elevated temperature with elimination of ammonia.
The end product is a basic, pale yellow, pulverizable, water-soluble hate, which can be converted into water-soluble salts with the help of suitable organic or inorganic acids. The basic product as well as its water-soluble salts are suitable as: those or together with water-soluble compounds of polyvalent metals such as copper to improve the fastness properties of dyeings with nouns dyes, for the production of pigments or for the animalization of cellulosic fibers.
They also have the property of precipitating acidic dyes from their aqueous solutions.
Example: 146 g of triethylenetetramine bp. 270 to 271 C and 84 g of dicyanodiamide are introduced into a short reflux condenser and the temperature is first raised to 100 to 110 C, with ammonia being split off. At 110 ° C. the mass becomes clear, and the temperature is slowly increased to 140 ° C. in accordance with the reaction and maintained that way.
After 14 to 16 hours, the mass is taken out, cooled and pulverized. It can be used as such or as a neutral salt, optionally with copper salts, to improve the fastness of dyeings with substantive dyes.
The condensation product produced according to the example can be used as follows in concentrations of 0.1 to 2.0 g / liter to improve the fastness properties of dyeings with substantive dyes, both from the condensation product itself and from. its water-soluble salts or complexes with polyvalent metals:
In. a solution of 0.3 g of the condensation product described in the example per liter at a liquor ratio of, for example, 1: 30, a 2% coloration of the blue substantive dye No. 617 Schultz, dye tables, vol. I, edition 1931, on Viscose introduced.
The dye is treated in it with frequent changing at temperatures between 20 and 100 ° C. for 5 to 20 minutes. The post-treated piece can be centrifuged off and dried with or without intermediate rinsing. In certain cases, post-treatment at elevated temperature improves the washfastness of dyeings with substantive dyes even further.
Hot drying, on the other hand, is by no means necessary because the still wet, directly spun off pieces have excellent fastness even without intermediate drying in alkaline washing liquors.
There can also be other substantive colorations such. B. those with black no. <B> 671 </B> and blue no. 513 Schultz, Färbstofftabellen, Vol. I, edition 1931, can be improved with the above condensation products.
