Description
Terfahren zur Herstellung einer neuen Base. Es wurde gefunden, dass man zu einer neuen Base gelangt, wenn man das Amid aus technischer Stearinsäure mit Formaldehyd zum N-Methylolamid umsetzt und anschlie ssend auf das so erhaltene N-Methylolamid ein Salz des Monomethylamins und.Form aldehyd einwirken lässt.
Die Umsetzung des N-Methylolamids mit dem Salz wird zweckmässig in Gegenwart einer Säure ausgeführt, z. B. in Anwesenheit von Eisessig, welcher gleichzeitig als Lö sungsmittel wirkt.
Die neue Base bildet ein weisses Pulver, welches in verdünnten Säuren löslich ist. Die Salze der neuen Base können als Textilhilfs mittel, z. B. als Weichmachungsmittel, An wendung finden.
<I>Beispiel:</I> 4 Teile einer Monomethylaminacetat- lösung in Eisessig, die 255'o7 Base enthält, werden mit 20 Volumteilen Eisessig ver dünnt, worauf man bei 70-80 unter Rühren 8 Teile N-Methylolstearinsäureamid, welches aus technischem Stearinsäureamid mit Formaldehyd erhalten wurde, einträgt. Nachdem sich letzteres klar aufgelöst hat, fügt man zum Reaktionsgemisch 2 Teile Para- formaldehyd und rührt letzteres bei der an gegebenen Temperatur so lange,
bis eine Probe desselben in verdünnter Essig- oder Ameisensäure klar löslich ist; was zirka 90 Minuten dauert. Nach dem Abdestillieren des Eisessigs imVakuum wird der Rückstand mit Wasser verrührt und gleichzeitig mit Natronlauge alkalisch gestellt. Man erhält dabei die neue Base als weisses Pulver, welches in verdünnten Säuren löslich ist.
Die stark schäumenden Lösungen dersel ben zeigen kationaktive Eigenschaften und fällen sulfogruppenhaltige Farbstoffe aus ihren Lösungen aus. Das Produkt ist ein hervorragendes Weichmachungsmittel für Textilien.
Driving to create a new base. It has been found that a new base is obtained if the amide from technical stearic acid is reacted with formaldehyde to form N-methylolamide and then a salt of monomethylamine und.formaldehyde is allowed to act on the N-methylolamide thus obtained.
The reaction of the N-methylolamide with the salt is conveniently carried out in the presence of an acid, e.g. B. in the presence of glacial acetic acid, which also acts as a solvent.
The new base forms a white powder that is soluble in dilute acids. The salts of the new base can be used as textile auxiliaries such. B. as a plasticizer, to find application.
<I> Example: </I> 4 parts of a monomethylamine acetate solution in glacial acetic acid, which contains 255'o7 base, are diluted with 20 parts by volume of glacial acetic acid, whereupon 8 parts of N-methylol stearic acid amide, which is made of technical Stearic acid amide was obtained with formaldehyde, enters. After the latter has clearly dissolved, 2 parts of paraformaldehyde are added to the reaction mixture and the latter is stirred at the given temperature until
until a sample of the same is clearly soluble in dilute acetic or formic acid; which takes about 90 minutes. After the glacial acetic acid has been distilled off in vacuo, the residue is stirred with water and at the same time made alkaline with sodium hydroxide solution. The new base is obtained as a white powder which is soluble in dilute acids.
The highly foaming solutions dersel ben show cation-active properties and precipitate sulfo-containing dyes from their solutions. The product is an excellent softener for textiles.
