使用上の注意
アルゴン封入
説明
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.
化学的特性
p-Anisaldehyde is a colorless to slightly yellowish liquid with a sweet, mimosa, hawthorn odor. It occurs in many essential oils, often together with anethole. It can be hydrogenated to anise alcohol and readily oxidizes to anisic acid when exposed to air. It is miscible in alcohol, ether, and most fixed oils, soluble in propylene glycol, insoluble in glycerin, water, and mineral oil.
天然物の起源
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.
製造方法
By methylation and oxidation of p-cresol and also by oxidation of anethole.
一般的な説明
p-anisaldehyde is an aromatic aldehyde commonly found in anise seed oil. It shows acaricidal activity and is primarily used, as a lead compound for the development of new agents for the selective control of house dust mites.
安全性プロファイル
Moderately toxic by
ingestion. A skin irritant. Mutation data
reported. Combustible liquid. When heated
to decomposition it emits acrid smoke and
irritating fumes
代謝
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).
純化方法
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.]
