Description
Verfahren zur Herstellung eines Kondensationsproduktes aus 1,1,4-Trimethyl-cyclohepten-(2)-aldehyd-(3) und Aceton. Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung eines bis her unbekannten Kondensationsproduktes aus 1,1,4-Trimethyl-cyclohepten- (2)-aldehyd-(3) und Aceton, welches dadurch gekennzeichnet ist, dass man ein Gemisch des 1,1,4-Trimethyl- cyclohepten-(2)-aldehyd-(3) und des Acetons mit einem Kondensationsmittel behandelt.
Das Kondensationsprodukt ist eine bei 98-100 (0,2 mm) siedende Flüssigkeit, weist Veilchengeruch auf und kann als Riech stoff verwendet werden.
<I>Beispiel:</I> 100 gr 1,1,4-Tricnethyl-cyclohepteti-(2)- aldehyd-(3) werden in 200 cm3 Aceton gelöst und mit einer Lösung von 5 gr Natrium in 75<B>cm,'</B> Methylalkohol versetzt. Das Gemisch wird nach einiger Zeit mit Oxalsäure ange- säuert und nach dem Abdestillieren der Lö sungsmittel in Äther aufgenommen und mit Sodalösung gewaschen. Der Siedepunkt des Kondensationsproduktes liegt bei 98 -100 (0,2 mm).
Process for the preparation of a condensation product from 1,1,4-trimethyl-cycloheptene- (2) -aldehyde- (3) and acetone. The present invention relates to a process for the preparation of a previously unknown condensation product from 1,1,4-trimethyl-cycloheptene- (2) -aldehyde- (3) and acetone, which is characterized in that a mixture of 1,1 , 4-trimethyl-cycloheptene- (2) -aldehyde- (3) and acetone treated with a condensing agent.
The condensation product is a liquid boiling at 98-100 (0.2 mm), has a violet odor and can be used as a fragrance.
<I> Example: </I> 100 g 1,1,4-tricnethyl-cyclohepteti- (2) -aldehyde- (3) are dissolved in 200 cm3 acetone and mixed with a solution of 5 g sodium in 75 cm , '</B> methyl alcohol added. After some time, the mixture is acidified with oxalic acid and, after the solvents have been distilled off, taken up in ether and washed with soda solution. The boiling point of the condensation product is 98-100 (0.2 mm).
