  <B>Zusatzpatent</B> zum Hauptpatent Nr. 154507.    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    verestert.  



  Es wurde nun gefunden, dass man in ganz  analoger Weise ein wertvolles Produkt erhält,  wenn man     Sulfoessigsäure    in der     Carboxyl-          gruppe    mit     Octodecylalkohol        verestert.    Der       Octodecylalkohol    kann beispielsweise erhalten  werden durch Reduktion von<B>Öl-</B> oder Stearin  säure beziehungsweise deren Estern. Man  kann ferner den     Octodecylalkohol    auch ge  winnen durch Reduktion von tierischen oder  pflanzlichen Ölen beziehungsweise Fetten, wie  Sojaöl,     Erdnussöl        etc.     



  Die     Veresterung    kann in üblicher Weise  erfolgen. Zweckmässig erhitzt man die     Sulfo-          essigsäure    mit     Octodecylalkohol    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 er  hält, wobei ein Äquivalent an Alkali, bezogen  auf die     Sulfogruppe,    verbraucht wird. Erhitzt  man das auf diese Weise erhaltene Natrium  salz mit der äquivalenten Menge     Octodecyl-          alkohol    auf etwa 180   C, so tritt     Veresterung     ein.

   An Stelle der     Sulfoessigsäure    kann man  auch Derivate der     Sulfoessigsäure,    beispiels  weise die Ester oder     Halogenide,    verwenden.  



  Die auf die beschriebene Weise herge  stellte Verbindung stellt ein farbloses Produkt  dar und eignet sich ebenso wie das nach  dem Verfahren der Hauptanmeldung erhält  liche Produkt vor allem als Wasch-,     Emulgier-,     Netzmittel     etc.    und kann insbesondere in der      Textilindustrie in vielseitiger Weise Verwen  dung finden.  



  <I>Beispiel:</I>  162 Teile     1>Iononatriumsalz    der     -Sulfoessig-          säure    werden mit 270 Teilen     Octodecylalko-          hol    8 Stunden lang unter Rühren auf 200   C  erhitzt, wobei man durch einen Stickstoffstrom  das bei der     Veresterung    freiwerdende Wasser  aus dem Reaktionsgefäss entfernt. Es bildet  sich ein wasserlösliches farbloses Produkt von  gutem Wasch-,     Reinigungs-    und     Dispergier-          vermögen,    das zum Beispiel auch als     Weich-          machungsmittel    für Kunstseide verwendbar  ist.



  <B> Additional patent </B> to main patent No. 154507. 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, emulsifier, 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 octodecyl alcohol. The octodecyl alcohol can be obtained, for example, by reducing oleic or stearic acid or their esters. The octodecyl alcohol can also be obtained by reducing animal or vegetable oils or fats, such as soybean oil, peanut oil, etc.



  The esterification can take place in the usual way. It is expedient to heat the sulfoacetic acid with octodecyl alcohol to about 100 ° C., whereby it is 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 one 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 octodecyl alcohol, esterification occurs.

   Instead of sulfoacetic acid, derivatives of sulfoacetic acid, for example the esters or halides, can also be used.



  The compound produced in the manner described is a colorless product and, like the product obtained by the process of the main application, is particularly suitable as a detergent, emulsifier, wetting agent, etc. and can be used in many ways, especially in the textile industry Find.



  <I> Example: </I> 162 parts of 1> ionosodium salt of sulfoacetic acid are heated with 270 parts of octodecyl alcohol to 200 ° C. for 8 hours with stirring, the water released during the esterification being removed from the reaction vessel by a stream of nitrogen away. A water-soluble, colorless product with good washing, cleaning and dispersing properties is formed, which can also be used, for example, as a plasticizer for rayon.
