Gebiet der ErfindungField of the Invention
Die Erfindung betrifft spezielle Riechstoff-Zusammensetzungen, die 90-70 Gew.% 2-Methylen-3-(4-methylcyclohex-3-enyl)-butanal und 10-30 Gew.% Limonen- aldehyd enthalten.The invention relates to special fragrance compositions which contain 90-70% by weight of 2-methylene-3- (4-methylcyclohex-3-enyl) butanal and 10-30% by weight of limonaldehyde.
Stand der TechnikState of the art
Limonen, dessen rationeller IUPAC-Name l-Methyl-4-isopropenyl-cyclohex-l-en lautet, ist ein bekannter Naturstoff. Die Strukturformel von Limonen (3) ist nachstehend wiedergegeben:Limonene, whose rational IUPAC name is l-methyl-4-isopropenyl-cyclohex-l-ene, is a well-known natural product. The structural formula of limonene (3) is shown below:
Limonen (3)Lime (3)
Aus DE 29 21 619 C3 ist bekannt, daß Limonen durch Hydroformylierung leicht in 3-(4-Methylcyclohex-3-enyl)-butanal überführt werden kann. Bei der Hydroformylierung handelt es sich um eine dem Fachmann bekannte Reaktion, die bereits 1938 durch von Roelen entdeckt wurde. Dabei werden Alkene mit Kohlenmonoxyd und Wasserstoff in Aldehyde überführt. Die Reaktion ist auch als Oxo-Synthese bekannt.It is known from DE 29 21 619 C3 that limonene can easily be converted into 3- (4-methylcyclohex-3-enyl) butanal by hydroformylation. Hydroformylation is a reaction known to the person skilled in the art, which was discovered in 1938 by von Roelen. Alkenes with carbon monoxide and hydrogen are converted into aldehydes. The reaction is also known as oxo synthesis.
Die Strukturformel von 3-(4-Methylcyclohex-3-enyl)-butanal, im folgenden auch als Limonenaldehyd (2) bezeichnet, ist nachstehend wiedergegeben: Limonenaldehyd (2)The structural formula of 3- (4-methylcyclohex-3-enyl) butanal, also referred to below as limonene aldehyde (2), is shown below: Limonene aldehyde (2)
Gemäß DE 29 21 619 C3 läßt sich nun Limonenaldehyd durch Methylenierung mit Formaldehyd in 2-Methylen-3-(4-methylcyclohex-3-enyl)-butanal (1) überfuhren, dessen Strukturformel wie folgt ist:According to DE 29 21 619 C3, limonene aldehyde can now be converted into 2-methylene-3- (4-methylcyclohex-3-enyl) -butanal (1) by methyleneation with formaldehyde, the structural formula of which is as follows:
2-Methylen-3-(4-methylcyclohex-3-enyl)-butanal2-methylene-3- (4-methylcyclohex-3-enyl) butanal
2-Methylen-3-(4-methylcyclohex-3-enyl)-butanal (1) läßt sich nach den Angaben der genannten DE 29 21 619 C3 als Duftstoff einsetzen. Über die Eigenschaften spezieller Mischungen von (1) mit anderen olfaktorisch wirksamen Verbindungen ist in der DE 29 21 619 C3 jedoch nichts offenbart.2-methylene-3- (4-methylcyclohex-3-enyl) butanal (1) can be used as a fragrance according to the information given in DE 29 21 619 C3. However, nothing is disclosed in DE 29 21 619 C3 about the properties of special mixtures of (1) with other olfactory compounds.
Viele natürliche Riechstoffe stehen gemessen am Bedarf in völlig unzureichender Menge zur Verfügung. Es ist daher klar, daß die Riechstoffindustrie einen ständigen Bedarf an neuen Riechstoffen mit interessanten Duftnoten hat, um die Palette der natürlich verfügbaren Riechstoffe zu ergänzen und die notwendigen Anpassungen an wechselnde modische Geschmacksrichtungen vornehmen sowie den ständig steigenden Bedarf an Geruchsverbessern für Produkte des täglichen Bedarfs wie Kosmetika und Reinigungsmittel decken zu können.Many natural fragrances are available in completely inadequate amounts, measured according to need. It is therefore clear that the fragrance industry has a constant need for new fragrances with interesting fragrance notes to complement the range of naturally available fragrances and to make the necessary adjustments to changing fashionable flavors as well to meet the ever increasing need for odor improvers for everyday products such as cosmetics and cleaning agents.
Darüberhinaus besteht generell ein ständiger Bedarf an synthetischen Riechstoffen, die sich günstig und mit gleichbleibender Qualität herstellen lassen und erwünschte olfaktorische Eigenschafen haben, das heißt angenehme, möglichst naturnahe und qualitativ neuartige Geruchsprofile von ausreichender Intensität besitzen und in der Lage sind, den Duft von kosmetischen und Verbrauchs gutem vorteilhaft zu beeinflussen. Es besteht daher Bedarf an Verbindungen und/oder Riechstoff- Zusammensetzungen, die charakteristische neue Geruchsprofϊle bei gleichzeitig hoher Haftfestigkeit, Geruchsintensität und Strahlkraft haben.In addition, there is generally a constant need for synthetic fragrances that can be produced cheaply and with consistent quality and have desired olfactory properties, that is, pleasant, natural and qualitatively novel odor profiles of sufficient intensity and able to smell cosmetic and To influence consumption good advantageous. There is therefore a need for compounds and / or fragrance compositions which have characteristic new odor profiles with high adhesive strength, odor intensity and radiance.
