Description

  

  Verfahren zur Herstellung einer im Kern substituierten aromatischen     Sulfonsäure.       Es wurde gefunden, dass man eine im  Kern substituierte aromatische     Sulfonsäure     erhält, wenn man auf den     p-Octadecylphenyl-          methyläther    der Formel     018H37.        06H4    - 0 .     CHs,     wie er erhältlich ist durch     Methylieren    des  Kondensationsproduktes aus     Octadecen-1.2     und Phenol,     Chlorsulfonsäure    einwirken lässt.  



  Die durch Umsetzung mit     Ätzalkalien,     z. B. Natronlauge, Kalilauge entstehenden       Alkalisalze    sind wasserlöslich und hervor  ragend     kapillaraktiv.    Sie sind besonders als  Wasch- und Netzmittel zu     verwenden.     



  <I>Beispiel:</I>  In 73 Gewichtsteile des     p-Octadecylphe-          ny1methyläthers,    erhalten durch     Methylieren     des Kondensationsproduktes aus     Octadecen-          1.2    und Phenol, werden 29 Gewichtsteile       Chlorsulfonsäure    langsam eingetragen, so dass  die Temperatur 400 nicht übersteigt. Sobald  das     Reaktionsprodukt    klar wasserlöslich ge  worden ist, was etwa nach 1 Stunde der    Fall ist, versetzt man mit der gleichen Menge  Wasser und neutralisiert mit Natronlauge.  Nach dem Eindampfen erhält man ein ganz  wenig     gelbstichiges    Pulver von vorzüglichen  Wascheigenschaften.



  Process for the preparation of an aromatic sulfonic acid substituted in the nucleus. It has been found that an aromatic sulfonic acid substituted in the nucleus is obtained if one uses the p-octadecylphenyl methyl ether of the formula 018H37. 06H4 - 0. CHs, as it can be obtained by methylating the condensation product of octadecene-1,2 and phenol, allowing chlorosulfonic acid to act.



  The reaction with caustic alkalis, z. B. caustic soda, caustic potash resulting alkali salts are water-soluble and excellent capillary activity. They are particularly useful as detergents and wetting agents.



  <I> Example: </I> 29 parts by weight of chlorosulfonic acid are slowly introduced into 73 parts by weight of the p-octadecylphenyl methyl ether, obtained by methylating the condensation product of octadecene 1,2 and phenol, so that the temperature does not exceed 400. As soon as the reaction product has become clearly water-soluble, which is the case after about 1 hour, the same amount of water is added and the mixture is neutralized with sodium hydroxide solution. After evaporation, a very slightly yellowish powder with excellent washing properties is obtained.
