Description

  

  Verfahren zur Herstellung     eines    neuen     Kondensationsproduktes.       Es wurde gefunden, dass man zu einem  neuen     Kondensationsprodukt    gelangt, wenn  man technisches     Stearinsäuremonohydrazid     mit     Acetonsulfonsäure    kondensiert und das  erhaltene Kondensationsprodukt anschliessend  reduziert.  



  Die Kondensation     des    technischen Stearin  säuremonohydrazids mit der     Acetonsulfon-          säure,    die zweckmässig in Form eines Alkali  salzes verwendet wird, erfolgt     vorteilhaft    in  der Wärme und in Gegenwart eines Lösungs  mittels,     wie    Äthylalkohol. Zur nachfolgenden  Reduktion eignet sich     insbesondere    Natrium  amalgam, das man zweckmässig unter Zusatz  von Wasser einwirken lässt.  



  Das     Natriumsalz    des so erhaltenen neuen  Kondensationsproduktes bildet ein hellgefärb  tes, in Wasser lösliches Pulver. Seine wässeri  gen Lösungen schäumen stark und besitzen  hervorragende Wascheigenschaften. Es kann  als     Tegtilhilfsstoff,    z. B. als     Waschmittel,     verwendet werden.  



       Beispiel:          44    Teile eines     Hydrazidgemisches,    welches  aus     techn.        Stearinsäure        hergestellt    wurde,  werden in 280     Volumteilen    Alkohol gelöst.  Dazu werden unter Rühren 84 Teile     aceton-          sulfonsaures    Natrium gegeben. Hierauf     wird     während 4 Stunden unter     Rückflusskühlung     gekocht, wobei bereits nach kurzem Erhitzen  sich das     acetonsulfonsaure    Natrium auf  löst.

   Nach dem     Abdestillieren    des Alko-         hols    erhält man das     Kondensationspro-          dukt        als    weisses Pulver, das in Wasser klar  löslich ist. Die wässerigen     Lösungen    schäu  men stark und zeigen ein gutes Waschver  mögen. Beim     Ansäuern    der wässerigen Lö  sung mit Mineralsäuren tritt     in    der Wärme  nach kurzer Zeit Trübung ein, wobei das  Schaumvermögen verschwindet.

   Um ein Pro  dukt zu erhalten, das gegen Mineralsäure auch  in der Hitze beständig ist, werden zur alkoho  lischen Lösung 120 Teile destilliertes Wasser  und unter Rühren bei 40 bis 50  pro Stunde  860     Teile    2%iges     Natriumamalgam    zugege  ben, bis im ganzen 1440 Teile eingetragen  sind. Nach dem Neutralisieren mit Schwefel  säure     wird    vom Quecksilber abgegossen und  der Alkohol     abdestilliert,    worauf das Reduk  tionsprodukt als hellgefärbtes Pulver erhalten       wird,    das in Wasser löslich ist. Die wässerigen  Lösungen schäumen stark und besitzen her  vorragende Wascheigenschaften.



  Process for the production of a new condensation product. It has been found that a new condensation product is obtained if technical-grade stearic acid monohydrazide is condensed with acetone sulfonic acid and the condensation product obtained is then reduced.



  The condensation of the technical stearic acid monohydrazide with the acetone sulfonic acid, which is conveniently used in the form of an alkali salt, is advantageously carried out in the heat and in the presence of a solvent such as ethyl alcohol. Sodium amalgam, which is expediently allowed to act with the addition of water, is particularly suitable for the subsequent reduction.



  The sodium salt of the new condensation product thus obtained forms a light colored, water-soluble powder. Its aqueous solutions foam strongly and have excellent washing properties. It can be used as Tegtilhilfsstoff, z. B. can be used as a detergent.



       Example: 44 parts of a hydrazide mixture, which from techn. Stearic acid was prepared, are dissolved in 280 parts by volume of alcohol. 84 parts of sodium acetone sulfonic acid are added to this with stirring. This is then refluxed for 4 hours, the sodium acetonsulfonic acid already dissolving after a short period of heating.

   After the alcohol has been distilled off, the condensation product is obtained as a white powder which is clearly soluble in water. The aqueous solutions foam strongly and show good washing properties. When the aqueous solution is acidified with mineral acids, turbidity occurs after a short time when heated, and the foaming power disappears.

   In order to obtain a product that is resistant to mineral acid even in the heat, 120 parts of distilled water are added to the alcoholic solution and 860 parts of 2% sodium amalgam are added with stirring at 40 to 50 per hour, up to a total of 1440 parts are. After neutralizing with sulfuric acid, the mercury is poured off and the alcohol is distilled off, whereupon the reduction product is obtained as a light-colored powder that is soluble in water. The aqueous solutions foam strongly and have excellent washing properties.
