Description

  

  Verfahren zur Herstellung eines als Netz-,     Reinigungs-,        Emulgiermittel        ete.     geeigneten     Produktes.       In der Hauptanmeldung ist ein Verfahren  zur Herstellung eines als Netz-,     Reinigungs-,          Emulgiermittel        etc.    geeigneten Produktes be  schrieben, bei dem man     Sulfoessigsäure    in  der     Carboxylgruppe    mit     Oleinalkohol        ver-          estert.     



  Es wurde nun gefunden, dass man in ganz  analoger Weise ein wertvolles Produkt erhält,  wenn man     Sulfoessigsäure    in der     Carboxyl-          gruppe    mit     Tetradecylalkohol    verestert. Der       Tetradecylalkohol    kann beispielsweise erhal  ten werden durch Reduktion von     Myristinsäure          bezw.    deren Estern.

   Man kann ferner den     Te-          tradecylalkohol    gewinnen durch Reduktion von  solchen pflanzlichen Ölen     bezw.    Fetten, die  wie das     Palmkernöl    und     Kokosöl        Myristin-          säure        bezw.    deren Ester enthalten, und nach  folgende fraktionierte Destillation.  



  Die     Veresterung    kann in üblicher Weise  erfolgen.     Zweckmässig    erhitzt man die Sulfo-         essigsäure    mit     Tetradecylalkohol    auf etwa  100  C, wobei es vorteilhaft ist, durch An  wendung von Vakuum das bei der     Vereste-          rung    freiwerdende Wasser zu entfernen.

       Statt     der freien     Sulfoessigsäure    kann man auch  das     Monoalkalisalz,    zum Beispiel das Mono  natriumsalz, verwenden, das man leicht durch  Neutralisieren der wässerigen Lösung der       Sulfoessigsäure    mit Natronlauge bis zum  Verschwinden der kongosauren Reaktion  erhält, wobei ein Äquivalent an Alkali, be  zogen auf die     Sulfogruppe,    verbraucht wird.  Erhitzt man das auf diese Weise erhaltene       Natriumsalz    mit der     äquivalenten    Menge       Tetradecylalkohol    auf etwa 180   C, so tritt       Veresterung    ein.  



  Die auf die beschriebene Weise hergestellte  Verbindung stellt ein farbloses, in Wasser  leicht lösliches, festes Produkt dar und eignet  sich ebenso wie das nach dem Verfahren der  Hauptanmeldung erhältliche Produkt vor      allem als Wasch-,     Emulgier-,    Netzmittel     etc.     und kann insbesondere in der Textilindustrie  in vielseitiger Weise Verwendung finden.  



  <I>Beispiel:</I>  214 Gewichtsteile     Tetradecylalkohol    wer  den mit 140 Gewichtsteilen     Sulfoessigsäure          1/z    Stunde lang im Vakuum auf<B>1000</B> C er  hitzt. Das erhaltene Produkt nimmt man  mit Wasser auf und neutralisiert es mit  Natronlauge. Die wässerige Lösung kann  wegen ihres vorzüglichen Wasch-, Netz-,       Dispergiervermögens    und dergleichen als  solche Verwendung finden. Auch als     Weich-          machungsmittel    für Kunstseide ist das Pro-         dukt    geeignet, man kann es durch Ein  dampfen auch in fester Form gewinnen.



  Process for the production of a wetting agent, cleaning agent, emulsifying agent. suitable product. The main application describes a process for the preparation of a product suitable as a wetting agent, cleaning agent, emulsifying agent, etc., in which sulfoacetic acid is esterified in the carboxyl group with oleic alcohol.



  It has now been found that a valuable product is obtained in a completely analogous manner if sulfoacetic acid in the carboxyl group is esterified with tetradecyl alcohol. The tetradecyl alcohol can, for example, be obtained by reducing myristic acid or. their esters.

   You can also win the Tetradecyl alcohol by reducing such vegetable oils BEZW. Fats that like palm kernel oil and coconut oil, myristic acid or. contain their esters, and after subsequent fractional distillation.



  The esterification can take place in the usual way. The sulfoacetic acid is expediently heated with tetradecyl alcohol to about 100 ° C., it being advantageous to remove the water released during the esterification by applying a vacuum.

       Instead of the free sulfoacetic acid, you can also use the monoalkali salt, for example the monosodium salt, which is easily obtained by neutralizing the aqueous solution of sulfoacetic acid with sodium hydroxide until the Congo acidic reaction disappears, with an equivalent of alkali, based on the sulfo group, is consumed. If the sodium salt obtained in this way is heated to about 180 ° C. with the equivalent amount of tetradecyl alcohol, esterification occurs.



  The compound produced in the manner described is a colorless, solid product that is readily soluble in water and, like the product obtainable by the process of the main application, is particularly suitable as a detergent, emulsifier, wetting agent, etc. can be used in many ways.



  <I> Example: </I> 214 parts by weight of tetradecyl alcohol are heated with 140 parts by weight of sulfoacetic acid for 1 / 2h in a vacuum to <B> 1000 </B> C. The product obtained is taken up in water and neutralized with sodium hydroxide solution. The aqueous solution can be used as such because of its excellent washing, wetting and dispersing properties and the like. The product is also suitable as a plasticizer for rayon; it can also be obtained in solid form by steaming.
