Description

  

  Verfahren zur Herstellung einer neuen     Estersäure.       Es wurde gefunden, dass man eine neue       Estersäure,    die     Cetylhexahydrophthalester-          säure,    erhält, wenn man 1     Mol        Oetylalkohol     auf 1     Mol        Hexahydrophthalsäureanhydrid    ein  wirken lässt.

   Die     Cetyihexahydrophthalester-          säure    bildet mit Alkalien und Ammoniak  wasserlösliche Salze, deren wässerige Lösun  gen hohe Netz- und Waschkraft besitzen und  als     Textilhilfsprodukte,    insbesondere     alsWeich-          machungsmittel,    verwendet werden können.

    <I>Beispiel:</I>  <B>60,5</B> Gewichtsteile     Cetylalkohol    werden  in 37 Gewichtsteile geschmolzenes     Hexahy-          di-ophthalsäureanhydrid    eingetragen und     auf.     150-160   gehalten, bis das Reaktionsprodukt  in verdünnter     Ammoniaklösung    klar löslich  ist, was nach kurzer Zeit der Fall ist. Man    lässt erkalten und neutralisiert die entstandene       Cetylhexahydrophthalestersäure    unter Zusatz  von Wasser mit     Ammoniaklösung.  



  Process for the preparation of a new ester acid. It has been found that a new ester acid, the cetylhexahydrophthalic acid, is obtained if 1 mole of ethyl alcohol is allowed to act on 1 mole of hexahydrophthalic anhydride.

   Cetyihexahydrophthalester acid forms water-soluble salts with alkalis and ammonia, the aqueous solutions of which have high wetting and washing power and can be used as textile auxiliary products, in particular as softeners.

    <I> Example: </I> <B> 60.5 </B> parts by weight of cetyl alcohol are added to 37 parts by weight of molten hexahydi-ophthalic anhydride and added. 150-160 held until the reaction product is clearly soluble in dilute ammonia solution, which is the case after a short time. It is allowed to cool and the resulting cetylhexahydrophthalic ester acid is neutralized with ammonia solution with the addition of water.
