Description
Verfahren zur Herstellung eines neuen Kondensationsproduktes. Es wurde gefunden, dass man züa einem neuen Kondensationsprodukt gelangt,' wenn man Laurinsäure-N-methylolamid in Gegen wart einer Säure mit Chloressigsäureamid umsetzt und an das Kondensationsprodukt Pyridin addiert.
Die Umsetzung wird zweckmässig in Gegenwart eines Lösungsmittels, wie Alkohol, Aceton, Dioxan, Eisessig, vorgenommen. Als Säure kann beispielsweise Salzsäure, Schwefel säure, Essigsäure Anwendung finden.
Das neue Kondensationsprodukt bildet ein annähernd farbloses, kristallinisches Pulver-, das von Wasser zu einer beim Schütteln stark schäumenden Lösung aufgenommen wird, und eignet sich insbesondere zum Weich machen von Viskosekunstseide.
Beispiel: Man verrührt 18 Gewichtsteile Laurin- säuremethylolamid, <B>11,1</B> Gewichtsteile Chlor- essigsäureamid und 60 Volumteile absoluten Alkohol kurze Zeit bei 50-55 , fügt 30 Volumteile alkoholische Salzsäure hinzu, wo- bei sofortige Lösung erfolgt, und hält die Temperatur während etwa 30 Minuten auf 50-55 . Dabei scheiden sich allmählich farblose Kristalle aus. Die nach dem Er kalten von der Mutterlauge abgetrennten Kristalle werden unter vermindertem Druck bei 60-6b getrocknet.
Zur Anlagerung von Pyridin verrührt man 9 Gewichtsteile des so dargestellten, im Vakuum von anhaften dem Chlorwasserstoff völlig befreiten Kon densationsproduktes mit 45 Volumteilen trockenem Pyridin während 15 Stunden bei 50-55 , lässt erkalten, trennt die ausge fallenen Kristalle von der Mutterlauge, wäscht mit wenig Diäthyläther nach und lässt das anhaftende Lösungsmittel bei Zimmertempe ratur verdunsten.
Das so erhaltene, annähernd farblose, quaternäre Pyridiniumsalz, dem aller Wahrscheinlichkeit nach die Formel
EMI0001.0023
zuzuschreiben ist, wird vom Wasser zu einer beim Schütteln stark schäumenden Lösung aufgenommen und eignet sich insbesondere zum Weichmachen von Viskosekunstseide.
Process for the production of a new condensation product. It has been found that a new condensation product is obtained if lauric acid N-methylolamide is reacted with chloroacetic acid amide in the presence of an acid and pyridine is added to the condensation product.
The reaction is expediently carried out in the presence of a solvent such as alcohol, acetone, dioxane, glacial acetic acid. As an acid, for example, hydrochloric acid, sulfuric acid, acetic acid can be used.
The new condensation product forms an almost colorless, crystalline powder that is absorbed by water to form a strongly foaming solution when shaken, and is particularly suitable for softening viscose rayon.
Example: 18 parts by weight of lauric acid methylolamide, 11.1 parts by weight of chloroacetic acid amide and 60 parts by volume of absolute alcohol are stirred for a short time at 50-55, 30 parts by volume of alcoholic hydrochloric acid are added, which results in immediate dissolution, and keeps the temperature at 50-55 for about 30 minutes. Colorless crystals gradually separate out. The crystals separated from the mother liquor after cooling are dried under reduced pressure at 60-6b.
For the addition of pyridine, 9 parts by weight of the condensation product thus represented, completely freed from adhering hydrogen chloride in vacuo, is stirred with 45 parts by volume of dry pyridine for 15 hours at 50-55, allowed to cool, the crystals which have precipitated out are separated from the mother liquor and washed with little Diethyl ether and allows the adhering solvent to evaporate at room temperature.
The almost colorless quaternary pyridinium salt thus obtained, which in all probability has the formula
EMI0001.0023
can be attributed to, is absorbed by the water into a strongly foaming solution when shaken and is particularly suitable for softening viscose rayon.
