Description
Verfahren zur Herstellung eines neuen .Kondensationsproduktes. Es wurde gefunden, dass man zu einem neuen Kondensationsprodukt gelangt, wenn man 1 Mol Stearinsäureamid mit mindestens 2 Mol a,a'-Dichlordimethyläther und darauf mit Thioharnstoff behandelt.
Die Umsetzung des Kondensationspro duktes aus Stearinsäureamid und a,ä -Di- chlordimethyläther mit Thioharnstoff wird zweckmässig in Gegenwart eines Lösungs mittels, wie Aceton oder Alkohol, ausge führt.
Das neue Produkt stellt ein weisses Pul ver dar, das sich in warmem Wasser unter Bildung stark schäumender Lösungen auf löst, welch letztere, insbesondere nach Zu satz von Natriumacetat, sich nach kurzem Kochen unter Abscheidung unlöslicher, amorpher Produkte zersetzen. Das neue Pro dukt kann zum waschechten Wasserabsto ssend- und Weichmachen von Textilien ver wendet werden.
Beispiel: 14,1 Gewichtsteile Stearinsäureamid wer den unter Feuchtigkeitsausschluss und unter Rühren mit 28 Gewichtsteilen symmetri schem Dichlordimethyläther versetzt, worauf das Gemisch während 4 Stunden auf 85 bis 95 erhitzt wird. Anfänglich setzt eine hef tige Chlorwasserstoffgasentwicklung ein, die allmählich abnimmt und nach der angegebe nen Zeit völlig beendigt ist. Der überschüs sige Dichlordimethyläther wird sodann ab destilliert, zuletzt unter vermindertem Druck.
220 Gewichtsteile des so erhaltenen Kon densationsproduktes werden bei 20' allmäh lich zu einer Aufschlemmung von 91 Ge wichtsteilen fein pulverisiertem Thioharn- stoff in 800 Volumteilen absolutem Alkohol unter Rühren hinzugefügt. Man lässt die Temperatur auf 45 bis<B>50'</B> steigen und hält dieselbe während ca. 1/z Stunde auf der an gegebenen Höhe. Der Thioharnstoff löst sich dabei allmählich auf, und es entsteht eine farblose, klare Lösung. Sobald eine Probe der Lösung mit Wasser verdünnt völlig klar bleibt, ist die Reaktion beendigt.
Nach dem Abdestillieren des Alkohols im Vakuum bei 40 bis<B>50'</B> bleibt das Kondensationsprodukt als anfänglich klebrige Masse zurück, die beim Abkühlen auf Ü völlig erstarrt und dann eine leicht pulverisierbare Masse er gibt.
Das neue Produkt stellt ein weisses Pul ver dar, das sich in warmem Wasser unter Bildung stark schäumender Lösungen auf löst, welch letztere insbesondere nach Zusatz von Natriumacetat sich nach kurzem Kochen unter Abscheidung unlöslicher, amorpher Produkte zersetzt.
Process for the production of a new condensation product. It has been found that a new condensation product is obtained if 1 mol of stearic acid amide is treated with at least 2 mol of a, a'-dichlorodimethyl ether and then with thiourea.
The reaction of the condensation product from stearic acid amide and α, α-dichlorodimethyl ether with thiourea is expediently carried out in the presence of a solvent such as acetone or alcohol.
The new product is a white powder that dissolves in warm water to form strongly foaming solutions, which, in particular after adding sodium acetate, decompose after brief boiling with the separation of insoluble, amorphous products. The new product can be used to repel water and soften textiles.
Example: 14.1 parts by weight of stearic acid amide, with exclusion of moisture and with stirring, mixed with 28 parts by weight of symmetrical dichlorodimethyl ether, whereupon the mixture is heated to 85 to 95 for 4 hours. Initially, a strong evolution of hydrogen chloride gas sets in, which gradually decreases and is completely terminated after the specified time. The excess dichlorodimethyl ether is then distilled off, finally under reduced pressure.
220 parts by weight of the condensation product thus obtained are gradually added at 20 'to a slurry of 91 parts by weight of finely pulverized thiourea in 800 parts by volume of absolute alcohol with stirring. The temperature is allowed to rise to 45 to 50 'and is kept at the given level for about 1/2 hour. The thiourea gradually dissolves and a colorless, clear solution is formed. As soon as a sample of the solution, diluted with water, remains completely clear, the reaction has ended.
After the alcohol has been distilled off in vacuo at 40 to 50 ', the condensation product remains as an initially sticky mass, which completely solidifies when it cools to Ü and then gives it an easily pulverizable mass.
The new product is a white powder that dissolves in warm water to form strongly foaming solutions, the latter, especially after the addition of sodium acetate, decomposes after brief boiling with the separation of insoluble, amorphous products.
