Description
Verfahren zur Herstellung eines neuen Kondensationsproduktes. Es wurde gefunden, dass man zu einem neuen Kondensationsprodukt gelangt, wenn man Laurinsäuremethylolamid in Gegenwart einer Säure mit Glycerinmercaptan umsetzt.
Die Umsetzung wird zweckmässig in Ge genwart eines Lösungsmittels, wie Eisessig, Dioxan, vorgenommen. Als Säure kann bei spielsweise Salzsäure, Schwefelsäure, Essig säure Anwendung finden.
Das neue Kondensationsprodukt ist eine weiche, in Wasser lösliche Masse und kann als Textilhilfsstoff verwendet werden.
<I>Beispiel:</I> 7,7 Gewichtsteile Laurinsäuremethylol- amid werden in 70 Volumenteilen Dioxan gelöst. Hierauf werden 4,0 Gewichtsteile Glycerinmercaptan zugegeben und unter Eis kühlung 7 Volumenteile konzentrierte Schwe felsäure unter Rühren zugetropft. Nach dem Stehen über Nacht bei gewöhnlicher Tempe ratur wird unter Eiskühlung mit Natronlauge vorsichtig neutralisiert und im Vakuum bei 50-60 zur Trockne verdampft. Nach dem Ausziehen mit absolutem Alkohol, Verdampfen des letzteren und Auswaschen mit wenig Äther wird das neue Produkt als weiche, in Wasser lösliche Masse erhalten.
Process for the production of a new condensation product. It has been found that a new condensation product is obtained if lauric acid methylolamide is reacted with glycerol mercaptan in the presence of an acid.
The reaction is expediently carried out in the presence of a solvent such as glacial acetic acid or dioxane. The acid can be used for example hydrochloric acid, sulfuric acid, acetic acid.
The new condensation product is a soft, water-soluble mass and can be used as a textile auxiliary.
<I> Example: </I> 7.7 parts by weight of lauric acid methylolamide are dissolved in 70 parts by volume of dioxane. Then 4.0 parts by weight of glycerol mercaptan are added and, while cooling with ice, 7 parts by volume of concentrated sulfuric acid are added dropwise with stirring. After standing overnight at normal temperature, it is carefully neutralized with sodium hydroxide solution while cooling with ice and evaporated to dryness in vacuo at 50-60. After soaking in absolute alcohol, evaporating the latter and washing it out with a little ether, the new product is obtained as a soft, water-soluble mass.
