Description
Verfahren zur Darstellung eines Gemisehes -von hÖhermololculareu aliphatischen Sulftden. Es ist bereits bekannt gewordeD, Mereap- tane mit Halogen enthaltenden alipbatischen Verbindungen umzusetzell, wobei auch bereits eine Komponente durch Carboxylgruppen sub stituiert war. Es hat sich dabei bisher aber immer nur um niedere aliphatische oder um gemischt aromatisch-aliphatische Verbindun gen gehandelt, die keine technische Bedeutung besassen.
Es wurde nun gefunden, dass man zu einem Gemisch technisch wertvoller Sulfide hö erer organischer Verbindungen, die Seifencharakter besitzen, gelangen kann, wenn man ein Ge misch höherer Alkylhalogenide, das dem durch Reduktion natürlich vorkommender Fette und Öle erhältlichen Alkoholgemisch entspricht, mit dem Natriumsalz der Mereaptoessigsäure umsetzt.
Das neue Gemisch der Natriumsalze höhe rer Alkylmereaptoessigsäuper) besitzt seifen artige und emulgierende Eigenschaften. Es lässt sich unter anderem als Hilfsstoff in der Textilindustrie und als Seifenersatzstoff ver wenden. <I>Beispiel:</I> <B>16</B> Gewichtsteile Ätznatron werden in<B>300</B> Gewichtsteilen Alkohol gelöst und nach und nach mit 18,4 Gewichtsteile Mereaptoessig- säure versetzt.
Darauf werden 47 Gewichts teile eines Gemisches höherer Alkylehloride, die den durch Reduktion der Cocosölfettsäuren erhältlichen Alkoholen entsprechen, zugege ben. Das Gemisch wird 4 Stunden am Rück- flusskühler auf dem Wasserbad erhitzt. Nach beendeter Reaktion wird heiss filtriert. Beim Erkalten kristallisiert das Gemisch der Nat- riumsalze der höheren Alkylmereaptoessig- säuren als weisse Kristallmasse aus.
Das neue Produkt ist in Wasser klar löslich; die wäss- rigen Lösungen zeigen gutes Schaumvermö gen. Es kann als Seifenersatzstoff verwendet werden.
Process for the preparation of a mixture of higher molecular weight aliphatic sulphides. It has already become known to react mereapatans with halogen-containing aliphatic compounds, one component also already being substituted by carboxyl groups. So far, however, it has always been a question of lower aliphatic or mixed aromatic-aliphatic compounds that were of no technical importance.
It has now been found that a mixture of technically valuable sulfides of higher organic compounds that have soap character can be obtained if a mixture of higher alkyl halides, which corresponds to the alcohol mixture obtainable by reducing naturally occurring fats and oils, is mixed with the sodium salt of Mereaptoacetic acid converts.
The new mixture of sodium salts of higher alkylmereaptoacetic acids) has soap-like and emulsifying properties. It can be used, among other things, as an auxiliary in the textile industry and as a soap substitute. <I> Example: </I> <B> 16 </B> parts by weight of caustic soda are dissolved in <B> 300 </B> parts by weight of alcohol, and 18.4 parts by weight of mereaptoacetic acid are gradually added.
Then 47 parts by weight of a mixture of higher alkyl chlorides, which correspond to the alcohols obtainable by reducing the coconut oil fatty acids, are added. The mixture is refluxed on a water bath for 4 hours. After the reaction has ended, it is filtered hot. On cooling, the mixture of sodium salts of the higher alkyl mereaptoacetic acids crystallizes out as a white crystal mass.
The new product is clearly soluble in water; the aqueous solutions show good foaming power. It can be used as a soap substitute.
