Description

         

  Verfahren zur Herstellung     eines-esterartigen    Kondensationsproduktes.    Im Hauptpatent ist, ein Verfahren zur  Herstellung eines     esterartigen    Kondensations  produktes beschrieben, welches dadurch     ge,     kennzeichnet ist, dass man     Octadecylchlor-          methyläther    der Formel         Ci8H27.0.        CHIC1       mit einem essigsauren     Alkalimetallsalz    zur  Umsetzung bringt.  



  Gegenstand der vorliegenden Erfindung  ist ein Verfahren zur     Herstellung    eines     ester-          artigen        Kondensationsproduktes,    welches da  durch gekennzeichnet ist, dass man Stearin  säurechlormethylamid der Formel         Cr;H"CO.NH.        CH,Cl       mit einem essigsauren     Alkalimetallsalz    zur  Umsetzung bringt.  



  Das entstandene     esterartige    Kondensa  tionsprodukt hat die Formel         C,    ;     H;,CO.        NH.        CH2.        OCOCH3       und ist ein kristalliner,     wasserunlöslicher     Körper mit dem Schmelzpunkt 83 bis<B>85',</B>  der sich in organischen Lösungsmitteln auf  löst. Das neue Produkt soll als Textilhilfs  mittel Verwendung finden.  



  Die Umsetzung wird zweckmässig so aus  geführt, dass man die     Chlormethylverbindung     in einem organischen     Lösungsmittel    mit dem  essigsauren     Alkalisalz    erwärmt, das aus  geschiedene anorganische Salz     abfiltriert    und  das Lösungsmittel verdampft.         Beispiel:     Eine Lösung von 106 Gewichtsteilen       Stearinsäurechlormethylamid    in 800 Gei  wichtsteilen     Tetrachlorkohlenstoff    wird mit.  50 Gewichtsteilen trockenem     Kaliumacetat     versetzt und 8 Stunden lang zum Sieden er  wärmt. Nach dem Erkalten wird das Un  gelöste abgesaugt und das Filtrat im Vakuum  bei<B>50'</B> eingedampft.

   Der Rückstand wird  aus Methanol umkristallisiert und zeigt hier-           nach    einen     Schmelzpunkt    von 58 bis<B>62'.</B>  Nach dem     Umlösen    aus z. B.     Methvlenchlorid     und     Abfiltrieren    der     schwerstlöslichen    An  teile erhält man das Produkt mit einem       Sehmelzpunkt    von etwa 88 bis<B>85'.</B>



  Process for the preparation of an ester-like condensation product. The main patent describes a process for the production of an ester-like condensation product, which is characterized in that octadecyl chloromethyl ether of the formula Ci8H27.0. CHIC1 with an acetic acid alkali metal salt to implement.



  The present invention relates to a process for producing an ester-like condensation product, which is characterized in that stearic acid chloromethylamide of the formula Cr; H "CO.NH. CH, Cl is reacted with an alkali metal salt of acetic acid.



  The resulting ester-like condensation product has the formula C,; H;, CO. NH. CH2. OCOCH3 and is a crystalline, water-insoluble body with a melting point of 83 to <B> 85 ', </B> which dissolves in organic solvents. The new product is to be used as a textile aid.



  The reaction is expediently carried out in such a way that the chloromethyl compound is heated in an organic solvent with the acetic acid alkali salt, the inorganic salt which has separated out is filtered off and the solvent is evaporated. Example: A solution of 106 parts by weight of chloromethyl stearic acid in 800 parts by weight of carbon tetrachloride is added. 50 parts by weight of dry potassium acetate added and heated for 8 hours to the boil. After cooling, the undissolved material is suctioned off and the filtrate is evaporated in vacuo at <B> 50 '</B>.

   The residue is recrystallized from methanol and then shows a melting point of 58 to 62 '. After redissolving from z. B. Methvlenchlorid and filtering off the poorly soluble to parts, you get the product with a melting point of about 88 to <B> 85 '. </B>
