  <B>Zusatzpatent</B>     zum    Hauptpatent Nr. 248209.         Verfahren    zur Herstellung     eines    neuen     Halbesters.       Es wurde     gefunden,    dass man zu einem  neuen     Halbester    gelangt, wenn man 1     Mol          Stearinsäure-ss-oxyäthylester    mit 1     Mol        Malein-          säure    oder     Maleinsäureanhydrid    umsetzt.  



  Es ist vorteilhafter,     Maleinsäureanhydrid     als     Maleinsäure    selbst zu verwenden.  



  Die Umsetzung     wird    zweckmässig in der  Wärme, z. B. bei 90 bis 120 , vorgenommen.  Nenn man     Maleinsäure    als Ausgangsstoff  verwendet, ist es vorteilhaft,     unter    Zusatz  einer geringen Menge     einer    starken Säure mit  dem     Stearinsäure-ss-oxyäthylester    zu erhitzen,  bis 1     Mol    Wasser abgespalten ist.  



  Das     Natriumsalz    des neuen Halbesters bil  det eine annähernd farblose, in     warmem    Was  ser schäumend lösliche Masse. Es kann als  Textilhilfsmittel verwendet werden.  



       Beispiel:     Man erhitzt<B>6,3</B> Teile     S,tearinsäure-ss-oxy-          äthylester    und 2,1 Teile     Maleinsäureanhydrid     unter Rühren während     etwa   <B>3</B> Stunden auf    95 bis 100 , löst das     Veresterungsgemisch    in       Äthylalkohol,    neutralisiert mit verdünnter       Natriumhydroxydlösung    und dampft zur  Trockne ein.     Das    so erhaltene neue Natrium  salz, das durch Extraktion mit Aceton von  einer geringen Menge eines Nebenproduktes  befreit werden kann, bildet eine annähernd  farblose, in warmem Wasser schäumend lös  liche Masse.

   Es kann als     Textilhilfsmittel    ;       verwendet    werden.



  <B> Additional patent </B> to main patent No. 248209. Process for the production of a new half-ester. It has been found that a new half ester is obtained if 1 mole of stearic acid ss-oxyethyl ester is reacted with 1 mole of maleic acid or maleic anhydride.



  It is more beneficial to use maleic anhydride than maleic acid itself.



  The implementation is expediently in the heat, for. B. at 90 to 120 made. If maleic acid is used as the starting material, it is advantageous, with the addition of a small amount of a strong acid, to heat the stearic acid ss-oxyethyl ester until 1 mol of water has been split off.



  The sodium salt of the new half-ester forms an almost colorless mass that foams and dissolves in warm water. It can be used as a textile auxiliary.



       Example: One heats <B> 6.3 </B> parts of S, tearic acid-ss-oxy-ethyl ester and 2.1 parts of maleic anhydride with stirring for about <B> 3 </B> hours to 95 to 100, this dissolves Esterification mixture in ethyl alcohol, neutralized with dilute sodium hydroxide solution and evaporated to dryness. The new sodium salt obtained in this way, which can be freed from a small amount of a by-product by extraction with acetone, forms an almost colorless mass that foams in warm water.

   It can be used as a textile auxiliary; be used.
