酢酸1-フェニルエチル 化學(xué)特性,用途語(yǔ),生産方法
外観
無色～うすい黃色、液體
説明
α-Methylbenzyl acetate has an intensive green odor suggestive of
gardenia with a bitter, acrid taste, interesting on dilution. May be
prepared by acetylation of methyl phenyl carbinol; from benzaldehyde by reacting with magnesium methyl bromide and subsequent acetylation; from 1-bromoethylbenzene and silver acetate in
acetic acid.
化學(xué)的特性
CLEAR COLOURLESS TO PALE YELLOWISH LIQUID
天然物の起源
Reported found in gardenia flower oil and avocado.
使用
Styralyl Acetate is a freshening compound with Alkoxylated Phenols.
Styralyl acetate finds extensive use in flavor compositions, particularly the "sharp"-fruity
types, Pineapple, Apricot, Gooseberry, Apple,
but also in Plum, Peach and many berry or
fruit complexes.
The concentration is about 1 to 30 ppm in
the finished product.
製造方法
By acetylation of methyl phenyl carbinol; from benzaldehyde by reacting with magnesium methyl bromide and subse quent acetylation; from 1-bromoethylbenzene and silver acetate in acetic acid.
代謝
Although no published data exist on the metabolism of methylphenylcarbinyl acetate, it is likely that hydrolysis to the carbinol and acetic acid is the initial step. Williams (1959) reports studies in which 50% of a dose of (±)-methylphenylcarbinol given to rabbits was excreted as the glucuronide in the urine within 24 hr. There was some evidence of oxidation and demethylation, as mandelic and hippuric acids were found in the urine. Previously, El Masry, Smith
