  • Beschreibung p-Methoxybenzaldehyde has a characteristic hawthorne odor and a pungent, anise-like flavor. It has a bitter flavor above 30 - 40 ppm. May be prepared by methylation and oxidation of p-cresol and also by oxidation of anethole.
  • Chemische Eigenschaften p-Methoxybenzaldehyde has a sweet, floral odor and a pungent, anise-like flavor. It has a bitter flavor above 30 to 40 ppm.
  • Chemische Eigenschaften clear colorless to pale yellowish liquid
  • Chemische Eigenschaften p-Anisaldehyde occurs in many essential oils, often together with anethole. It is a colorless to slightly yellowish liquid with a sweet, mimosa, hawthorn odor. p-Anisaldehyde can be hydrogenated to anise alcohol and readily oxidizes to anisic acid when exposed to air. Synthetic routes to anisaldehyde start from p-cresyl methyl ether, which is oxidized, for example, by manganese dioxide or by oxygen or peroxy compounds in the presence of transition metal catalysts .
    Another industrial process uses electrochemical oxidation in the presence of lower aliphatic alcohols via the corresponding anisaldehyde dialkyl acetal . Anisaldehyde may also be produced by methylation of 4-hydroxybenzaldehyde, which is easily obtained by oxidation of p-cresol or by Vilsmeier formylation of anisol.
  • Occurrence Reported found in essential oils and extracts of vanilla, Acacia farmesiana Willd., Magnoila salicifolia Maxim., Erica arborea, Pirus communis, Boswellia serrata, and others; also in anise, fennel and star anise (especially when aged due to the oxidation of anethole), cranberry, black currant, cinnamon and basil.
  • Verwenden p-Anisaldehyde is a flavoring agent that is a colorless or faintly yellow liquid, hawthorn-like odor. It is miscible in alcohol, ether, and most fixed oils, soluble in propylene glycol, insoluble in glycerin, water, and mineral oil. It is obtained by synthesis. It is also termed anise aldehyde and p-methoxybenzaldehyde.
  • Verwenden Perfumery and toilet soaps; odor resembles that of coumarin, but the aldehyde must be mixed with other odorous substances to yield an agreeable odor. Also used in organic syntheses.
  • synthetische By methylation and oxidation of p-cresol and also by oxidation of anethole.
  • Aroma threshold values Aroma characteristics at 1.0%: sweet powdery, spicy creamy, fruity, vanilla and hay-like. Coumarin, almond, anisic with berry nuances.
  • Taste threshold values Taste characteristics at 5 to 10 ppm: sweet powdery, vanilla creamy, spice anise, nutty, cherry pit and almond-like nuances.

  • Sicherheitsprofil Moderately toxic by ingestion. A skin irritant. Mutation data reported. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes
  • Stoffwechsel Anisic aldehyde undergoes a very slight degree of demethylation with oxidation of its aldehyde group to an acid group, the major metabolite excreted being anisic acid (Williams, 1959).
  • läuterung methode Wash the aldehyde with saturated aqueous NaHCO3, then H2O, steam distil, extract the distillate with Et2O, dry (MgSO4) the extract, filter and distil this under a vacuum and N2. Store it in glass ampules under N2 in the dark. [Beilstein 8 IV 252.]
