天然物の起源
Polyethylene bottles used in intravenous solutions have been reported to be contaminated with N-ethylaniline from rubber parts of the closure (Ulsaker and Teien 1979). It has been reported that rubber containing N,N,-dithiodimorpholine accelerator of vulcanization can release N-ethylaniline into an aqueous media (Stankevich and Shurupova 1976). This compound has also been reported as a contaminant of cigarette smoke at a level of 55.8 ng per one U.S. 85 mm cigarette (Patrianakos and Hoffmann 1979).
使用
N-Ethylaniline is used as an explosive stabilizer and in dyestuff manufacture.
一般的な説明
A dark liquid with an aromatic odor. Insoluble in water. Density 0.963 g / cm3. Toxic by skin absorption and inhalation of vapors. Evolves toxic fumes during combustion. Flash point 185°F.
使用用途
2-フェニルエチルアミンやその誘導体は、実験的に抗うつ作用を持つことが証明されています。そのため、抗うつ剤として利用可能です。 2-フェニルエチルアミンによって、「楽しさ」や「期待感」などを司るホルモンである、ドーパミンやの分泌を促します。特に、2-フェニルエチルアミンの働きにより、恋愛でホルモンの分泌が活発になると考えられており、「恋愛ホルモン」として注目されています。
製法・合成法
調製方法
Manufacture of N-ethylaniline is based on the reaction of aniline with alkyl halide or by heating aniline with ethyl alcohol under acidic conditions followed by purification (Windholz et al 1983).
