Description
Verfahren zur Herstellung eines neuen Textilhilfsmittels. Wir haben gefunden, dass durch die Sul- fonierungvon Hydroxylgruppen in ss,ss',ss"-Tri- hydroxy-tertiärbutylstearamid durch die Wir kung eines sulfonierenden .Agens, wie Oleum, ein neues Textilhilfsmittel mit wertvollen Eigenschaften erhalten wird. <I>Beispiel:</I> <B>60</B> Teile ss"-Trihydroxy-tertiärbutyl- stearamid werden langsam unter eifrigem Umrühren in 180 Teile 94 o/oiger Schwefel säure bei gewöhnlicher Temperatur gebracht.
Hierauf werden weitere 20 Teile Amid und 40 Teile 50 o/oiges Oleum dem Gemisch gleichzeitig zugesetzt. Das ganze wird 30 31i- nuten umgerührt und dann mit 15 o/oigem, wässerigem Natriumhydroxyd sorgfältig neu tralisiert.
Das Produkt bildet einen dünnen, weissen Teig, welcher zur Hauptsache aus dem Zweibasennatriumsalz des Dischwefelsäure- esters der wahrscheinlichen Formel besteht
EMI0001.0021
Es ist zum Beispiel gleichwertig dem Natriumsalz des Schwefelsäureesters von Ce- tylalkohol in neutraler Lösung und besser als letzterer in hartem Wasser oder Säure lösung.
Es hat eine ausgezeichnete, reinigende Wirkung auf Textilmaterialien in sauren und alkalischen Bädern und ist auch zum Gebrauch in hartem Wasser geeignet. Andere alkalische Metallsalze, zum Beispiel Kalium salze, werden durch Anwendung anderer Ätzalkalien an Stelle von Ätznatron erhal ten.
fl, ss', ss"-Trihydroxy-tertiärbutylstearamid kann hergestellt werden, indem man gleiche Mengen von Stearinsäure und ss, ss', ss"-Tri- hydroxy-tertiärbutylamin (vergleiche Piloty and Ruff, $er. 1897, 80; 1665, 2067) auf <B>180'</B> erhitzt bis Dampfentwicklung aufhört.
Durch Rekristallisation aus Methylalkohol wird das Produkt als ein weisses Pulver er halten.
Process for the production of a new textile auxiliary. We have found that the sulphonation of hydroxyl groups in ss, ss', ss "-trihydroxy-tert-butylstearamide through the action of a sulphonating agent such as oleum gives a new textile auxiliary with valuable properties. <I> Example : </I> <B> 60 </B> parts of ss "-trihydroxy-tertiary-butylstearamide are slowly brought into 180 parts of 94% sulfuric acid at ordinary temperature with vigorous stirring.
A further 20 parts of amide and 40 parts of 50% oleum are then added to the mixture at the same time. The whole is stirred for 30-31 minutes and then carefully neutralized with 15% aqueous sodium hydroxide.
The product forms a thin, white dough, which mainly consists of the two-base sodium salt of the disulfuric acid ester of the probable formula
EMI0001.0021
For example, it is equivalent to the sodium salt of the sulfuric acid ester of cetyl alcohol in neutral solution and better than the latter in hard water or acid solution.
It has an excellent cleaning effect on textile materials in acidic and alkaline baths and is also suitable for use in hard water. Other alkaline metal salts, for example potassium salts, are obtained by using other caustic alkalis instead of caustic soda.
fl, ss ', ss "-trihydroxy-tertiary-butylstearamide can be prepared by adding equal amounts of stearic acid and ss, ss', ss" -trihydroxy-tertiary-butylamine (compare Piloty and Ruff, $ er. 1897, 80; 1665, 2067) heated to <B> 180 '</B> until the development of steam ceases.
Recrystallization from methyl alcohol gives the product a white powder.
