Description
Verfahren zur Herstellung eines neuen Kondensationsproduktes. Es wurde gefunden, dass man ein neues Kondensationsprodukt erhält, wenn man das N-*-#Iethylolamid aus gehärteter Tranfettsäure in Gegenwart einer Säure auf Thioharnstoff einwirken lässt.
Die Umsetzung wird zweckmässig in Ge genwart eines Lösungsmittels, wie Alkohol, Eisessig, vorgenommen.
Das neue Kondensationsprodukt stellt in Form des Chlorhydrates ein annähernd farb loses, kristallines Pulver dar, das in organi schen Lösungsmitteln, wie Alkohol, Eisessig, Dioxan, löslich ist und beim Verdünnen der alkoholischen Lösung mit Wasser eine beim Schütteln stark schäumende Lösung ergibt, die sich beim Kochen oder auf Zusatz von Alkalien unter Bildung einer in Wasser un löslichen Verbindung zersetzt. Das neue Kon densationsprodukt kann als Textilhilfsstoff, insbesondere zum waschechten Wasserabsto ssend- und Weichmachen von Textilien, An wendung finden.
<I>Beispiel:</I> 150 Teile Amid aus gehärteter Tranfett- säure werden unter Rühren mit. 7,5 Teilen Dimethylcyclohexylamin und 18 Teilen Para- formaldehyd während 4 Stunden auf 105 bis 110 0 erhitzt. Das Reaktionsprodukt wird zu gegeben zu einer Lösung von 46 Teilen Thio- harnstoff in 750 Vol.-Teilen Alkohol und er hitzt, bis alles gelöst ist.
Hierauf wird unter Rühren auf<B>501'</B> abgekühlt, wobei ein Teil ausfällt und 90 Vol.-Teile alkoholische Salz- säure von 25% zugegeben. Bei einer Tem- peratur von 50-551 wird während einer Stunde weiter gerührt, wobei das zuerst aus gefallene Produkt langsam wieder in Lösung geht.
Nach Filtration von Unreinigkeiten wird abkühlen gelassen, wobei das annähernd farb lose, kristallinische Kondensationsprodukt aus fällt. Es wird filtriert uud im. Vakuum bei gewöhnlicher Temperatur getrocknet. Aus beute 164 Teile.
Das neue Produkt ist in organischen Lö- sungsmitteln löslich. Die beim Verdünnen der alkoholischen Lösung mit Wasser erhaltene Lösung schäumt beim Schütteln und zersetzt sich beim Kochen oder bei Zusatz von Al kalien.
Process for the production of a new condensation product. It has been found that a new condensation product is obtained if the N - * - # Iethylolamide from hardened trans-fatty acid is allowed to act on thiourea in the presence of an acid.
The reaction is expediently carried out in the presence of a solvent such as alcohol or glacial acetic acid.
The new condensation product is an almost colorless, crystalline powder in the form of the chlorohydrate, which is soluble in organic solvents such as alcohol, glacial acetic acid, dioxane and, when the alcoholic solution is diluted with water, results in a strongly foaming solution when shaken decomposes when boiling or when alkalis are added to form a compound which is insoluble in water. The new condensation product can be used as a textile auxiliary, in particular for waterproofing and softening textiles.
<I> Example: </I> 150 parts of amide from hardened trans-fatty acid are added while stirring. 7.5 parts of dimethylcyclohexylamine and 18 parts of paraformaldehyde are heated to 105 to 110 ° for 4 hours. The reaction product is added to a solution of 46 parts of thiourea in 750 parts by volume of alcohol and it is heated until everything has dissolved.
The mixture is then cooled to <B> 501 '</B> while stirring, a portion precipitating and 90 parts by volume of 25% alcoholic hydrochloric acid added. At a temperature of 50-551, stirring is continued for one hour, the product that precipitated out slowly going back into solution.
After filtering off impurities, the mixture is allowed to cool, and the almost colorless, crystalline condensation product precipitates out. It is filtered and im. Vacuum dried at ordinary temperature. From loot 164 parts.
The new product is soluble in organic solvents. The solution obtained when the alcoholic solution is diluted with water foams when shaken and decomposes when boiled or when alkali is added.
