Description
Verfahren zur Herstellung eines neuen Kondensationsproduktes. Es wurde gefunden, dass man zu einem neuen Kondensationsprodukte gelangt, wenn man Laurinsäuremethylolamid in Gegenwart von Halogenwasserstoff auf Thioharnstoff einwirken lässt.
Die Umsetzzmg wird zweckmässig in Ge genwart eines Lösungsmittels, wie Alkohol, vorgenommen.
Das neue Kondensationsprodukt ist eine halbfeste 14Zasse, die beim Kochen in wäss riger Lösung oder auf Zusatz von Alkalien unter Bildung einer wasserunlöslichen Ver bindung zerfällt. Es kann als Tegtilhilfs- stoff Anwendung finden.
Beispiel: 4,6 Teile Laurinsäurem@ethylolamid und 3 Teile Thioharnstoff werden in 40 Volum- teilen heissem Alkohol gelöst. Nach dem Abkühlen auf 50 fügt man unter Rühren 4 Volumteile 25%ige alkoholische Salzsäure hinzu und erwärmt während 20 Minuten auf 50 bis 55 . Hierauf ist eine Probe in Wasser unter starkem Schäumen klar löslich.
Nach dem Abdestillieren des Alkohols im Vakuum bleibt das Reaktionsprodukt als halbfeste Masse zurück, die beim Kochen in wässriger Lösung oder auf Zusatz von Alkalien unter Bildung einer wasserunlöslichen Verbindung zerfällt.
Process for the production of a new condensation product. It has been found that a new condensation product is obtained when lauric acid methylolamide is allowed to act on thiourea in the presence of hydrogen halide.
The conversion is expediently carried out in the presence of a solvent such as alcohol.
The new condensation product is a semi-solid substance that disintegrates when boiled in aqueous solution or when alkalis are added to form a water-insoluble compound. It can be used as a textile auxiliary.
Example: 4.6 parts of lauric acid ethylolamide and 3 parts of thiourea are dissolved in 40 parts by volume of hot alcohol. After cooling to 50, 4 parts by volume of 25% strength alcoholic hydrochloric acid are added with stirring and the mixture is heated to 50 to 55 for 20 minutes. A sample is then clearly soluble in water with strong foaming.
After the alcohol has been distilled off in vacuo, the reaction product remains as a semi-solid mass that disintegrates when boiling in aqueous solution or when alkalis are added to form a water-insoluble compound.
