Description

  

  Verfahren zur Darstellung eines     Gemisehes    von     höhermolekularen        aliphatischen        Sulfiden.       Im Hauptpatent<B>168132</B> ist ein Verfahren  zur Darstellung eines Gemisches von höher  molekularen     aliphatischen    Sulfiden beschrieben  worden, bei dem man ein Gemisch höherer       Alkylhalogerride,    das dem durch Reduktion  natürlich vorkommender Fette und Öle er  hältlichen Alkoholgemisch entspricht, mit  dein     Natriumsalz    der     lZercaptoessigsäure   <B>um-</B>  setzt.  



  Es wurde nun gefunden, dass man zu  einem Gemisch technisch wertvoller Sulfide  höherer organischer Verbindungen, die Seifen  charakter besitzen, auch dadurch gelangen  kann, dass man ein Gemisch der     Alkaliver-          bindungen    höherer     Alkylmercaptane,    das dem  durch Reduktion natürlich vorkommender  Fette und Öle erhältlichen Alkoholgemisch  entspricht, mit dein     Natriumsalz    einer     ss-Ha-          logerr-ätlran-a-sulfonsäure    umsetzt.  



  Das neue Gemisch der     Natriumsalze    hö  herer     Alkylmereaptoäthansulfonsänren    besitzt  seifenartige und     emulgierende    Eigenschaften.  Es lässt sich unter anderem als     Eilfsstoff    in    der Textilindustrie und als Seifenersatzstoff  verwenden.  



  <I>Beispiel:</I>  44 Gewichtsteile eines Gemisches höherer       Alkylmercaptarre,    die den durch Reduktion  der     Cocosölfettsäuren    erhältlichen Alkoholen  entsprechen, werden in alkoholischer Lösung  mit einer Lösung von 8 Gewichtsteilen Ätz  natron in Alkohol versetzt. Zu dieser Lösung  wird eine Lösung von 42 Gewichtsteilen     P-          Br#omäthan-a-sulfonsaurem    Natrium in 400  Gewichtsteilen Alkohol zugegeben. Das Ge  misch wird 3 Stunden am     Rückfiusskühler     auf dem Wasserbad erhitzt. Nach beendeter  Reaktion wird in der Wärme von dem bei  der Reaktion entstandenen Bromnatrium ab  filtriert.

   Beim Erkalten kristallisiert das       Gemisch    der     Natriumsalze    der höheren     Alkyl-          mercaptoäthansulfonsäuren    in Form einer  weissen Kristallmasse aus. Das neue Produkt  ist in Wasser klar löslich; die Lösungen  zeigen gutes Schaumvermögen. Es kann als       Seifenersatzstoff    verwendet werden.



  Process for the preparation of a mixture of higher molecular weight aliphatic sulfides. The main patent <B> 168132 </B> describes a process for the preparation of a mixture of higher molecular weight aliphatic sulfides, in which a mixture of higher alkyl halogerrides, which corresponds to the alcohol mixture obtained by reducing naturally occurring fats and oils, is mixed with the sodium salt which <B> converts </B> lzercaptoacetic acid.



  It has now been found that a mixture of technically valuable sulfides of higher organic compounds that have a soap character can also be obtained by using a mixture of the alkali compounds of higher alkyl mercaptans which corresponds to the alcohol mixture obtainable by reducing naturally occurring fats and oils , with the sodium salt of an ß-halogerr-ätlran-a-sulfonic acid.



  The new mixture of the sodium salts of higher alkyl mereaptoethane sulfonic acids has soap-like and emulsifying properties. It can be used as an auxiliary substance in the textile industry and as a soap substitute.



  <I> Example: </I> 44 parts by weight of a mixture of higher alkyl mercaptars, which correspond to the alcohols obtainable by reducing the coconut oil fatty acids, are mixed in an alcoholic solution with a solution of 8 parts by weight of caustic soda in alcohol. A solution of 42 parts by weight of sodium P-bromethane-a-sulfonic acid in 400 parts by weight of alcohol is added to this solution. The mixture is heated in the reflux condenser on the water bath for 3 hours. After the reaction has ended, the sodium bromide formed during the reaction is filtered off under warm conditions.

   On cooling, the mixture of the sodium salts of the higher alkyl mercaptoethanesulfonic acids crystallizes out in the form of a white crystal mass. The new product is clearly soluble in water; the solutions show good foaming power. It can be used as a soap substitute.
