Description

  

  Verfahren zur Herstellung eines neuen Kondensationsproduktes.    Es wurde gefunden, dass, man zu einem  neuen     Kondensationsprodukt    gelangt, wenn  man 1     Mol        p-Stearoylamino-benzamid    mit       mindestens    2     Mol        a,ä        -Dichlordimethyläther     und darauf mit     Pyridin        behandelt.     



  Das neue     Kondensationsprodukt    stellt  eine gelblich gefärbte, weiche Masse dar, die  sich in Wasser unter Bildung stark schäu  mender Lösungen klar auflöst, welch letztere,  insbesondere nach Zusatz von     Natriumacetat,     sich beim Erhitzen unter     Abscheidung    amor  pher, unlöslicher Produkte zersetzen, wobei  auch die Schaumfähigkeit allmählich ver  schwindet. Das neue Produkt kann zum       waschechten    Wasserabstossend- und Weich  machen von Textilien verwendet werden.

           Beispiel:     3 Gewichtsteile     p-Stearoylamino-benzamid     werden     mit    10 Gewichtsteilen     sym.        Dichlor-          dimethyläther    unter     Rühren    während 20  Stunden in einem Bad von     110-120'    er-         hitzt,    worauf der     grösste    Teil des Ausgangs  materials     in    Lösung gegangen ist.

   Nach ,dem       Abdestillieren    - des überschüssigen     Dichlor-          dimethyläthers    im Vakuum fügt man 10 Ge  wichtsteile     Pyridin    hinzu und erwärmt wäh  rend 20 Minuten unter Rühren auf dem  Dampfbad. Nach dem Entfernen des über  schüssigen     Pyridins    wird eine gelblich ge  färbte, weiche Masse erhalten, welche in  Wasser unter starkem     Schäumen    klar löslich  ist.

   Beim Erhitzen     .der        wässerigen    Lösung,  insbesondere auf Zusatz von     Natriumacetat,     verschwindet die Schaumfähigkeit allmäh  lich, und es scheiden sich amorphe, un  lösliche     Zersetzungsprodukte    ab.



  Process for the production of a new condensation product. It has been found that a new condensation product is obtained if 1 mol of p-stearoylamino-benzamide is treated with at least 2 mol of α, α-dichlorodimethyl ether and then treated with pyridine.



  The new condensation product is a yellowish-colored, soft mass that dissolves clearly in water to form strongly foaming solutions, which, in particular after the addition of sodium acetate, decompose when heated to deposit amorphous, insoluble products, with the foaming ability gradually disappears. The new product can be used to make textiles washable and water-repellent.

           Example: 3 parts by weight of p-stearoylamino-benzamide are heated with 10 parts by weight of sym. Dichlorodimethyl ether with stirring for 20 hours in a 110-120 'bath, whereupon most of the starting material has dissolved.

   After distilling off the excess dichloro dimethyl ether in vacuo, 10 parts by weight of pyridine are added and the mixture is heated on the steam bath while stirring for 20 minutes. After removing the excess pyridine, a yellowish colored, soft mass is obtained which is clearly soluble in water with strong foaming.

   When the aqueous solution is heated, in particular with the addition of sodium acetate, the foamability gradually disappears and amorphous, insoluble decomposition products separate.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Kondensationsproduktes, dadurch gekenn zeichnet, dass man 1 Mol p-Stearoylamino- 4, benzamid mit mindestens 2 Mol a,a'-Dichlor- di.methyläther,und darauf mit-Pyridin be handelt. PATENT CLAIM: A process for the preparation of a new condensation product, characterized in that 1 mol of p-stearoylamino-4, benzamide is treated with at least 2 mol of a, a'-dichlorodi.methyl ether, and then with pyridine. Das neue Produkt stellt eine gelblich ge färbte, weiche Masse dar, die sich in Wasser unter Bildung stark schäumender Lösungen klar auflöst, welch letztere, insbesondere nach Zusatz von Natriumacetat, sich beim Erhitzen unter Abscheidung amorpher, im- löslicher Produkte zersetzen, wobei auch die Schaumfähigkeit allmählich verschwindet. The new product is a yellowish colored, soft mass that dissolves clearly in water to form strongly foaming solutions, which, in particular after addition of sodium acetate, decompose when heated to deposit amorphous, insoluble products, including the Foaming ability gradually disappears.
