2-PHENYLPROPIONALDEHYDE 화학적 특성, 용도, 생산

화학적 성질
2-PHENYLPROPIONALDEHYDE identified in dried mushroom, is a colorless liquid with a green hyacinth odor. Hydratropaldehyde can be hydrogenated to hydratropic alcohol, which is also used to a limited extent by reaction of p-ethylbenzyl chloride and isobutyric aldehyde in the presence of catalysts. The product is used in perfumes for, for example, household products.
출처
Reported found in microbially fermented tea and some varieties of mushrooms.
용도
2-Phenylpropionaldehyde is a precursor in the synthesis of N,N,β-Trimethyl-phenethylamine Hydrochloride (T796625).
제조 방법
By alkaline condensation of acetophenone and ethyl chloroacetate; also by distillation of methylphenyl ethylene glycol in 91% yields (under atmospheric pressure).
생산 방법
The most important synthetic route to 2-phenylpropionaldehyde is the rhodiumcatalyzed hydroformylation of styrene. The catalyst [HCo(CO)4] is unsuitable in this process because it favors the hydrogenation of styrene. The use of chiral rhodium complexes leads to the formation of optically active aldehydes when prochiral olefins, such as styrene, are used. Asymmetric hydroformylation, however, has so far found only small industrial application because of insufficient purity of the enantiomers. Other synthetic methods are the gas-phase oxidation of a-methylstyrene on Cu, Bi–Mo– P–SiO2, or Pd salt catalysts, the rearrangement of epoxidized a-methylstyrene, and the dehydrogenation of 2-phenyl-1-propanol on Ag catalysts at reaction temperatures of ca. 600 ℃.
일반 설명
2-Phenylpropionaldehyde is used in perfumes for its green hyacinth odor.
상품명
Floralozone (IFF), Florazon (Symrise).
Safety Profile
: Moderately toxic by ingestion. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES.
Purification Methods
It may contain up to 15% of acetophenone. Purify it via the bisulfite addition compound [Lodge & Heathcock J Am Chem Soc 109 3353 1987] and see Chapter 2 for preparation and decomposition of bisulfite adducts. [Beilstein 7 IV 695.]
