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.
