| ALPHA,P-DIMETHYLSTYRENE Usage And Synthesis |
Chemical Properties | p,α-Dimethyl styrene has a citrusy-lemon-like aroma. | Chemical Properties | Clear colorless to light yellow liquid | Occurrence | Reported found in pepper, coffee, anise and parsley | Uses | α, p-dimethylstyrene has been suggested for
use in perfume compositions, mainly as a
component in certain artificial essential oils.
In Lemon fragrances for industrial masking
purposes it may introduce lift, power and
freshness. | Definition | ChEBI: P-Mentha-1,3,5,8-tetraene is a monocyclic hydrocarbon and a monoterpene. | Preparation | By passing a stream of p-cymene and water vapors over activated aluminum oxide at 730°C. | Taste threshold values | Taste characteristics at 2.5 ppm: spicy, balsamic, musty, and eugenol/guiacol-like with a nutty nuance. | Synthesis Reference(s) | Journal of the American Chemical Society, 118, p. 3970, 1996 DOI: 10.1021/ja9600486 The Journal of Organic Chemistry, 44, p. 3157, 1979 DOI: 10.1021/jo01332a014 Synthetic Communications, 19, p. 3353, 1989 DOI: 10.1080/00397918908052740 | General Description | p,α-Dimethylstyrene has been identified as one of the volatile flavor constituents in litchi, essential oils of distilled Mexican lime and parsley. |
