  Verfahren zur Darstellung von Hexamethylentetramindiguajakol. 



   Nach dem Verfahren des Stammpatentes Nr. 45443 wird ein   Hexamethylentetramintri-   guajakol durch Zusammenbringen einer konzentrierten, wässrigen Lösung von Hexamethylentetramin mit Guajakol oder einer   Formaldehydlösung   mit einer ammoniakalischen Guajakollösung erhalten. Es hat sich nun gezeigt, dass ausser dem   Hexamethylentetramintriguajakot   auch noch andere Molekularverbindungen zwischen Hexamethylentetramin und Guajakol beständig sind.

   Fügt man zu einer warmen Lösung von 8 kg Hexamethylentetramin in 10   1   Wasser 4 kg kristallisiertes Guajakol und erwärmt auf kochendem Wasserbade bis eine klare Lösung eingetreten ist, so kristallisieren beim Erkalten lange, feine Nadeln eines Körpers aus, der nach der Analyse ein   Hexamethylentetramindiguajakol   ist und in seinen wesentlichen Eigenschaften dem im Stammpatente beschriebenen Körper entspricht. 



  Das Hexamethylentetramindiguajakol lässt sich sehr leicht in seine Komponenten spalten.

  Process for the preparation of hexamethylenetetramine diguayakol.



   According to the process of the parent patent no. 45443, a hexamethylenetetramine triguaiacol is obtained by combining a concentrated, aqueous solution of hexamethylenetetramine with guaiacol or a formaldehyde solution with an ammoniacal guaiacol solution. It has now been shown that apart from hexamethylenetetramine triguajakot, other molecular compounds between hexamethylenetetramine and guaiacol are also stable.

   If you add 4 kg of crystallized guaiacol to a warm solution of 8 kg of hexamethylenetetramine in 10 1 of water and warm it on a boiling water bath until a clear solution has occurred, long, fine needles of a body crystallize out on cooling which, according to analysis, is a hexamethylenetetraminediguayakol and corresponds in its essential properties to the body described in the parent patent.



  The hexamethylenetetramine diguayakol can be split very easily into its components.

PATENT-ANSPRUCH : Verfahren zur Darstellung von Hexamethylentetramindiguajakol nach dem im Stammpatente Nr. 45443 geschützten Verfahren, dadurch gekennzeichnet, dass man entweder Guajakol und Hexamethylentetramin im ungefähren Verhältnis von 1 : 2 aufeinander einwirken lässt, oder Guajakol in ammoniakalischer Lösung mit einer diesem Verhältnis entsprechenden Menge Formaldehydlösung zusammenbringt. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the preparation of hexamethylenetetramine diguayakol according to the process protected in the parent patent No. 45443, characterized in that either guaiacol and hexamethylenetetramine are allowed to act on one another in an approximate ratio of 1: 2, or guaiacol in ammoniacal solution is combined with an amount of formaldehyde solution corresponding to this ratio. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
