| | P-TOLYL ACETATE Usage And Synthesis |
| Chemical Properties | Colorless, oily liquid; odor similar to
phenol. distillation with
steam. Insoluble in water; soluble in common
organic solvents. Combustible. | | 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. | | Definition | ChEBI: Tolylacetate is a member of phenols and a benzoate ester. | | Aroma threshold values | Detection: 25 ppb | | Synthesis Reference(s) | The Journal of Organic Chemistry, 43, p. 2417, 1978 DOI: 10.1021/jo00406a025 | | General Description | The Fries rearrangement of p-tolyl acetate has been investigated using the H-form of various zeolites as catalysts. Mechanism of photo-Fries rearrangement of p-tolyl acetate has been studied. | | Flammability and Explosibility | Notclassified | | Safety Profile | Moderately toxic by
ingestion and skin contact. Combustible
liquid. When heated to decomposition it
emits toxic smoke and irritating fumes. |
