4-메틸벤즈알데히드 C화학적 특성, 용도, 생산
화학적 성질
Clear colorless to pale yellow liquid. Soluble in alcohol and oils. Sweet-herbaceous, Bitter-almond-like moderately tenacious odor. Not as pungent as Benzaldehyde, but more herbaceous-warm. Intensely sweet, warm-fruity and Bitteralmond-like taste in concentrations lower than 500 ppm.용도
p-Tolualdehyde is made by the Vilsmeier reaction employing toluene and dimethylformamide or the Guttermann–Koch reaction employing toluene and carbon monoxide.정의
ChEBI: A tolualdehyde compound with the methyl substituent at the 4-position.일반 설명
p-Tolualdehyde (4-Methylbenzaldehyde) is an aromatic aldehyde. It has been generated as major oxygenated product during the UV light irradiated oxygenation of p-xylene, via photoinduced electron transfer mechanism. It undergoes condensation reaction with diiron μ-ethylidyne complex to afford μ-vinylcarbyne complex (92% yield).Purification Methods
Steam distil the aldehyde, dry it with CaSO4, then fractionally distil it. [Beilstein 7 IV 672.]4-메틸벤즈알데히드 준비 용품 및 원자재
