P-TOLYL ACETATE Chemical Properties,Uses,Production
Aroma
P-TOLYL ACETATE has pungent Lily-like odor, penetrating, floral,
Narcissus-like in high dilution, Horse-like,
urine-like undertones in higher concentration.
Pleasant notes are obtained normally at concentrations below 1% in the perfume creation,
but the material is still capable of totally
ruining a composition when the acetate is
applied in combination with certain fragrance
notes or single chemicals.
Finds some use in flavor compositions for
its intensely floral power, which can support
fruity notes, nut-like aromas, etc.
The concentration in the finished product is
usually about 0.5 to 10 ppm, but may reach
220 ppm in chewing gums.
Chemical Properties
Colorless liquid, volatile with steam. Poorly soluble in water, miscible with alcohol and oils. soluble in Propylene glycol. Sp.Gr. 1.05. B.P. 212°C.
Chemical Properties
p-Tolyl acetate has a strong, floral odor (narcissus) with a characteristic honey-like flavor
Occurrence
Reported as a constituent of the essential oils of wallflower, cananga and ylang-ylang.
Uses
Perfumery, flavoring.
Uses
p-Tolyl acetate has been used in the total synthesis of (?)-incrustoporin.
Preparation
By acetylation of p-cresol.
