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.
