Description

  

  Verfahren zur Herstellung eines für die Darstellung eines künstlichen  Kaffee-Aromas geeigneten Produktes.    Das     schweiz.    Patent 127511 hat ein Ver  fahren zur Darstellung eines künstlichen das  Kaffee-Aroma aufweisenden Produktes zum  Gegenstand, bei welchem man mindestens  eine     schwefelhaltigeVerbindung    mit mindestens  einer     sauerstoff-    oder stickstoffhaltigen Ver  bindung von der Art, wie sie im natürlichen       Kaffee-Aroma    enthalten ist, vermischt. Zweck  mässig wird als schwefelhaltige Verbindung  eine solche verwendet, die durch Einwirkung  eines     Merkaptans    auf eine mindestens eine       Carbonylgruppe    aufweisende Verbindung er  halten wurde.  



  Man kann auf ein     Merkaptan,    das den       Furfurylkern    enthält, z. B.     Furfuryl-2-merkap-          tan,    Produkte einwirken lassen, welche min  destens eine     Carbonylgruppe    aufweisen, und  erhält so die     a-Oxysulfide.    Als mindestens  eine     Carbonylgruppe    auf     weisendeVerbindungen     kommen Aldehyde und     Diketone    in Betracht.  



  Gegenstand vorliegender Erfindung ist nun  ein Verfahren zur Herstellung einer solchen  Schwefelhaltigen Verbindung, d. h. eines für    die Darstellung eines künstlichen     Kaffee-Aro-          mas    geeigneten Produktes. Gemäss diesem  Verfahren lässt man     Furfuryl-2-merkaptarr    und       Diacetyl    aufeinander einwirken.  



       Beispiel:     Man mischt molekulare Mengen von     Fur-          furyl-2-merkaptan    und     Diacetyl;    wobei sich  unter Erwärmen     (a-Oxy-a-acetyl-äthyl)-fur-          furyl-2-sulfid    bildet. Das erhaltene, bisher  unbekannte Produkt hat die Zusammensetzung  Co Hie     0s    S. Es ist ein farbloses 01 und nicht  uniersetzt destillierbar, sondern spaltet sich  dabei teilweise wieder in seine Komponenten.

    Spaltung tritt auch mit     Bisulfitlösung    ein, sowie  mit     Schwermetallsalzen,    welche das     Furfuryl-          merkaptan    fällen; in beiden Fällen tritt die  gelbe Farbe des     Diacetyls    auf. Das nach dem  vorliegenden Verfahren erhaltene Produkt ist  unlöslich in Wasser, löslich in organischen  Lösungsmitteln; mit Mineralsäuren tritt     Ver-          harzung    ein. Freie Alkalien spalten das Pro  dukt, wobei nachträglich das entstehende           Diacetyl    in bekannter Weise durch das Alkali  zersetzt wird.



  Process for the manufacture of a product suitable for displaying an artificial coffee aroma. Switzerland. Patent 127511 relates to a method for the preparation of an artificial coffee-flavored product, in which at least one sulfur-containing compound is mixed with at least one oxygen- or nitrogen-containing compound of the type contained in the natural coffee aroma. Appropriately, the sulfur-containing compound used is one which was obtained by the action of a mercaptan on a compound having at least one carbonyl group.



  One can refer to a mercaptan containing the furfuryl nucleus, e.g. B. furfuryl-2-mercap- tan, allow products to act which have at least one carbonyl group, and thus obtain the α-oxysulfide. Aldehydes and diketones are suitable as compounds having at least one carbonyl group.



  The present invention now provides a process for the preparation of such a sulfur-containing compound, i. H. a product suitable for the representation of an artificial coffee aroma. According to this procedure, furfuryl-2-mercaptar and diacetyl are allowed to act on one another.



       Example: Molecular quantities of furfuryl-2-mercaptan and diacetyl are mixed; whereby (a-oxy-a-acetyl-ethyl) -fur-furyl-2-sulfide is formed when heated. The so far unknown product obtained has the composition Co Hie 0s S. It is a colorless oil and cannot be distilled indefinitely;

    Cleavage also occurs with bisulfite solution and with heavy metal salts, which precipitate furfuryl mercaptan; in both cases the yellow color of the diacetyl appears. The product obtained by the present process is insoluble in water, soluble in organic solvents; resinification occurs with mineral acids. Free alkalis split the product, and the diacetyl formed is subsequently decomposed in a known manner by the alkali.
