Description
Zusatzpatent zum Hauptpatent Nr. 237621. Yerfähren- zur Verstellung eines negen Amdd"eri-vates. Es wurde gefunden, dass man zu einem neuen Amidderivat gelangt, wenn man etwa 1 Mal technisches Stearinsäureamid, etwa 1 Mol Formaldehyd und etwa 1 Mol Tri- äthanolamin aufeinander einwirken lässt.
Die Umsetzung wird vorteilhaft in der Wäxme, z. B. bei 100-140 , vorgenommen, zweckmässig unter Zusatz von die Reaktion beschleunigenden Stoffen, beispielsweise in Gegenwart von Alkalicarbonaten, wie Na- triumcarbonat.
Als Stoffe, die die Reaktion befördern, können auch konz. wasserlösliche organische Säuren, wie Eisessig oder Ameisensäure, die nen. Es ist zweckmässig, das Amid erst mit Formaldehyd in bekannter Weise zum N-Me- thylolamicl umzusetzen und anschliessend Tri- äthanolamin auf das N-Methylolamid ein wirken zu: lassen.
Das Acetat des neuen Amidderivates, eine annähernd feste Masse, wird von heissem Wasser zu einer opaleszierenden Lösung auf genommen. Es kann als Tegtilhilfsstoff, z. B. als -Weichmachungsmittel für Viskosekunst- seide, verwendet werden.
<I>Beispiel 1:</I> 250 Teile technisches Stearinsäureamid werden in bekannter Weise mit Hilfe von 36,3 Teilen Parafarmaldehyd ins Stearin säure-N-methylolamid übergeführt. Man fügt 160 Teile Triäthanolamin und 7,3 Teile was serfreies Natriumcarbonat hinzu und erhitzt unter Rühren auf 108 , wobei man das Re aktionsgefäss auf einen Unterdruck von etwa 20 cm Hg evakuiert.
Man rührt während etwa 3-4 Stunden bei 108-111 , nachdem der Unterdruck auf 40 cm Hg gesteigert worden ist. Das so erhaltene Kondensations- erzeugnis (437-440 Teile) wird anschlie- ssend mit 82 Teilen Eisessig neutralisiert und durch Zusatz von etwa 50 warmem Wasser in eine Paste übergeführt. Diese ist dickflüs sig,
annähernd farblos und eignet sich sehr gut als Weichmachungsmittel für Viskose kunstseide. Beispiel <I>2:</I> Technisches Stearinsäureamid wird in be kannter Weise mit Paraformaldehyd ins Stearinsäure - N - methylolamid übergeführt.
Man vermischt 12 Teile Steärinsäure-N-me- thylalamid aus technischer Stearinsäure mit 6,6 Teilen Triäthanolamin und 30 Teilen Eis essig und erhitzt _ während 3 Stunden unter Rühren auf 80-85 .
Die überschüssige Essigsäure wird darauf bei 60-65" unter vermindertem Druck abdestilliert, wobei man 25,6 Teile des Acetaten des neuen Kondensa- tionsproduktes erhält.
Letzteres, eine an nähernd feste Masse, wird von heissem Wasser zu einer opalen Lösung aufgenommen. Es kann als Weichmaehungsmittel, z. B. für Vis- kosekunstseide; verwendet werden.
Additional patent to the main patent no. 237621. Yerfähr- to adjust a negen Amdd "eri-vates. It has been found that a new amide derivative is obtained if technical stearic acid amide, about 1 mol of formaldehyde and about 1 mol of triethanolamine are used can interact.
The implementation is advantageous in the Wäxme, z. B. at 100-140, made, expediently with the addition of substances which accelerate the reaction, for example in the presence of alkali metal carbonates, such as sodium carbonate.
As substances that promote the reaction, conc. water-soluble organic acids, such as glacial acetic acid or formic acid. It is advisable to first react the amide with formaldehyde in a known manner to give N-methylolamicl and then to allow triethanolamine to act on the N-methylolamide.
The acetate of the new amide derivative, an almost solid mass, is taken up by hot water to form an opalescent solution. It can be used as a Tegtilhilfsstoff, z. B. can be used as a softener for viscose silk.
<I> Example 1 </I> 250 parts of technical stearic acid amide are converted into stearic acid-N-methylolamide in a known manner with the aid of 36.3 parts of parafarmaldehyde. 160 parts of triethanolamine and 7.3 parts of water-free sodium carbonate are added and the mixture is heated to 108 with stirring, the reaction vessel being evacuated to a reduced pressure of about 20 cm Hg.
The mixture is stirred for about 3-4 hours at 108-111 after the negative pressure has been increased to 40 cm Hg. The condensation product obtained in this way (437-440 parts) is then neutralized with 82 parts of glacial acetic acid and converted into a paste by adding about 50% of warm water. This is viscous,
almost colorless and is very suitable as a softener for viscose rayon. Example <I> 2 </I> Technical stearic acid amide is converted in a known manner with paraformaldehyde into stearic acid - N - methylolamide.
12 parts of stearic acid-N-methylalamide from technical stearic acid are mixed with 6.6 parts of triethanolamine and 30 parts of glacial acetic acid and heated to 80-85 for 3 hours with stirring.
The excess acetic acid is then distilled off at 60-65 "under reduced pressure, 25.6 parts of the acetate of the new condensation product being obtained.
The latter, an almost solid mass, is absorbed by hot water to form an opal solution. It can be used as a soft mulch, e.g. B. for viscose rayon; be used.
