Definitions

  • the invention relates to the use of special monocyclic aldehydes which are obtainable by partial or complete hydroformylation of (di) methyl-substituted cyclooct (adi) enes as fragrances.
  • Cyclooct (adi) enes here means both cyclooctadienes and cyclooctenes, that is to say Cg monocycles with one or two CbC double bonds.
  • (di) methyl-substituted it is meant that the bicyclic system carries either one or two methyl groups as substituents.
  • fragrance industry has a constant need for new fragrances with interesting fragrances to complement the range of naturally available fragrances and make the necessary adjustments to changing fashionable tastes as well as the ever-increasing need for odor-improving products for everyday needs such as To be able to cover cosmetics and cleaning agents.
  • a fragrance booster is to be understood as a substance that is able to give the olfactory impressions of the components of a multi-substance system, i.e. a mixture of two or more fragrances to intensify sustainably.
  • the invention relates to the use of monocyclic aldehydes, which are obtainable by partial or complete hydroformylation of (di) methyl-substituted cyclooct (adi) enes, as fragrances.
  • Another object of the invention is the use of monocyclic aldehydes, which are obtainable by partial or complete hydroformylation of (di) methyl-substituted cyclooct (adi) enes, as a fragrance booster.
  • monocyclic aldehydes which are obtainable by partial or complete hydroformylation of (di) methyl-substituted cyclooct (adi) enes, as a fragrance booster.
  • the compounds (3a), (3b) and (3c) described in more detail below are particularly preferred.
  • aldehydes to be used according to the invention are advantageously prepared by hydroformylation of (di) methyl-substituted cyclooct (adi) enes.
  • the latter compounds have a cyclooctane system as a common backbone.
  • 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.
  • the hydroformylation can be carried out partially or completely. Partial hydroformylation maintains one olefinic double bond per molecule of the starting compound, while only the other is hydroformylated; full hydroformylation introduces two CHO groups into the molecule. However, if (di) methyl-substituted cyclooctenes are used as starting materials, only complete hydroformylation is of course possible, since only one olefinic double bond is present per molecule of the starting compound.
  • the odor profile of the hydroformylation products according to the invention is original and new.
  • perfume compositions they enhance harmony and charisma as well as adhesion, whereby the dosage is adjusted to the desired fragrance, taking into account the other components of the composition.
  • Fragrances do not allow any conclusions to be drawn about the properties in the broadest sense of "structurally analogous" compounds - in the present case, for example, cyclooctanaldehyde (1) - or their mixtures with one another, because neither the mechanism of fragrance perception nor the influence of the chemical structure on fragrance perception have been adequately researched So it cannot normally be predicted whether a changed structure or special mixing ratios of known odoriferous substances will lead to a change in the olfactory properties and whether this change should be assessed positively or negatively.
  • the hydroformylation products according to the invention are particularly suitable for modifying and enhancing known compositions.
  • their extraordinary olfactory strength should be emphasized, which generally contributes to the refinement of compositions.
  • hydroformylation products according to the invention round off and harmonize the olfactory notes of a wide range of known compositions, but without dominating in an unpleasant manner.
  • the compounds (3a), (3b) and (3c) - compare the structural formulas below - are particularly suitable for use according to the invention as a fragrance and / or fragrance booster. Accordingly, the use of compounds (3a), (3b) and (3c) is particularly advantageous, for example, in room scents. In addition, it has been shown that the compounds (3a), (3b) and (3c) can be used with particular advantages in cleaning agents for strengthening citrus scents. CHO CHO ⁇ ⁇ CHO
  • the compounds (3 a), (3 b) and (3 c) can be prepared, for example, by hydroformylation of the corresponding (di) methyl-substituted cyclooctene or cyclooctadiene systems.
  • the usable proportions of the hydroformylation products according to the invention in fragrance compositions range from 0.001 to 70% by weight, based on the mixture as a whole.
  • the hydroformylation products according to the invention and compositions of this type can be used both for the perfuming of cosmetic preparations such as lotions, creams, shampoos, soaps, ointments, powders, aerosols, toothpastes, mouthwashes, deodorants and in exudate perfumery.

Abstract

L'invention concerne l'utilisation d'aldéhydes bicycliques comme matières odorantes, pouvant être obtenus par hydroformylation partielle ou totale de cyclo-oct(adi)ènes, éventuellement substitués par (di)méthyle. Ces composés se distinguent par une bonne rémanence et un bon pouvoir de diffusion. Ils ont en outre un effet renforçateur d'odeur.
