Description

  

  Verfahren zur     Darstelluug    einer höher molekularen Schwefelverbindung.    Das Hauptpatent Nr. 165506     betrifft    ein  Verfahren zur Darstellung einer     höhermole-          kularen        Sckwefelverbindung,    dadurch     gekenn-          zeicl)net,    dass man den     Schwefelsäureester    des       Dodecylalkohols        bezw.    ein Salz dieses Esters  mit wasserlöslichen     Sulfhydraten    umsetzt.  



       I    Es wurde nun gefunden, dass man zu  einer solchen höher molekularen Schwefel  verbindung auch dadurch gelangen kann,  dass man den     Schwefelsäureester    des     Dode-          cylalkohols    oder ein Salz desselben mit ss  Mercapto-äthan-a-sulfonsäure im alkalischen  Medium umsetzt.  



       Beispiel:     14,4     Gewichtsteile        dodecylschwefelsaures     Natrium und 9,3 Gewichtsteile der     Dinatrium-          verbindung    der     ss-Mercapto-äthan-a-sulfon-          sä        ure    werden mit 50     Volumteilen    70      /oigem     Alkohol zu einer Paste verrührt und im Auto  klaven 4 Stunden auf 160  erhitzt.

   Nach  dem Aufarbeiten erhält man in ausgezeich  neter Ausbeute das     Natriumsalz    der     ss-Do-          decylmereapto-äthan-a-sulfonsäure,    das aus  Alkohol umkristallisiert werden kann. Das    Produkt stellt eine weisse kristalline Masse  dar und löst sich in Wasser zu sehr     alkali-          und    säurebeständigen Lösungen, die ausge  zeichnetes Schaum-, Netz-,     Emulgier-    und       Dispergiervermögen    zeigen. Das Produkt  kann daher mit Vorteil als     Seifenersatzstoff     verwendet werden.



  Process for the preparation of a higher molecular weight sulfur compound. The main patent no. 165506 relates to a method for the preparation of a higher molecular weight sulfur compound, characterized in that the sulfuric acid ester of dodecyl alcohol is used. a salt of this ester is reacted with water-soluble sulfhydrates.



       It has now been found that such a higher molecular weight sulfur compound can also be obtained by reacting the sulfuric acid ester of dodecyl alcohol or a salt thereof with mercaptoethane-α-sulfonic acid in an alkaline medium.



       Example: 14.4 parts by weight of sodium dodecylsulfuric acid and 9.3 parts by weight of the disodium compound of ß-mercapto-ethane-α-sulfonic acid are mixed with 50 parts by volume of 70% alcohol to form a paste and left in the car for 4 hours for 160 heated.

   After working up, the sodium salt of β-dodecylmereapto-ethane-α-sulfonic acid, which can be recrystallized from alcohol, is obtained in excellent yield. The product is a white crystalline mass and dissolves in water to form very alkali and acid-resistant solutions with excellent foaming, wetting, emulsifying and dispersing properties. The product can therefore be used with advantage as a soap substitute.
