P-METHYLPHENYLACETALDEHYDE Chemical Properties,Usage,Production

Chemical Properties

p-Tolylacetaldehyde has a powerful and refreshing green-fruity, "forest-like", sweet, floral odor of moderate tenacity. The undiluted material has a rather sharp initial odor, but sweetness predominates in the diluted product. The taste is sweet-fruity, mildly green at concentrations near 10 ppm.

Uses

4-Methylphenylacetaldehyde (p-Tolylacetaldehyde) is used in perfumes, e.g., in soap, in tobacco fragrances, in the preparation of pesticides, etc.

Preparation

From p-methylbenzaldehyde; also from p-methylbenzyl chloride and hexamethylene tetramine.The methods of preparation correspond closely to those of phenylacetaldehyde. Thus, the compound can be prepared by glycidic ester synthesis from 4-methylbenzaldehyde and chloroacetate ester, by hydroformylation of 4-methylbenzylhalide with Co2(CO)8Na2CO3 in acetonitrile, or by oxidation of 4-methylstyrene.

Production Methods

p-Tolylacetaldehyde can be produced 1) from para-Methylbenzaldehyde via Darzen's reaction. 2) from para-Methylbenzy lchloride plus Hexamethyiene tetramine.

Definition

ChEBI: (4-Methylphenyl)acetaldehyde is a member of phenylacetaldehydes.

Taste threshold values

Taste characteristics at 10 ppm: sweet, fruity cherry with spicy an nutty nuances.
