p-Tolualdehyde Chemical Properties,Uses,Production
Chemical Properties
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.
Uses
p-Tolualdehyde is made by the Vilsmeier reaction employing toluene and dimethylformamide or the Guttermann–Koch reaction employing toluene and carbon monoxide.
Definition
ChEBI: A tolualdehyde compound with the methyl substituent at the 4-position.
Preparation
p-Tolualdehyde is prepared by oxidation of mixed Tolylalcohols.
General Description
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.]
