2-PHENYLPROPIONALDEHYDE Chemical Properties,Usage,Production
Description
2-phenylpropionaldehyde is also known as 2-phenylpropanal. It belongs to the family of phenylacetaldehydes. These are compounds containing a phenylacetaldehyde moiety, which consists of a phenyl group substituted at the second position by an acetalydehyde. 2- phenylpropionaldehyde is a naturally occurring compound in various foods including roasted nuts, cooked potatoes, cheese, wine, fruit, vegetables, coffee, tea, and cocoa. 2-phenylpropionaldehyde is used as a flavoring agent. Once absorbed, 2-phenylpropionaldehyde can be converted to phenyl-substituted carboxylic acids, which can be conjugated with glucuronic acid and excreted in the urine. 2-phenylpropionaldehyde can also undergo β- oxidation to benzoic acid or phenylacetic acid derivatives, which are conjugated with glycine or glutamine before being excreted in the urine.

Chemical Properties
clear colorless liquid
Chemical Properties
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.
Chemical Properties
2-Phenylpropionaldehyde has an intense, green, floral odor reminiscent of hyacinth.
Occurrence
Reported found in microbially fermented tea and some varieties of mushrooms.
Uses
2-Phenylpropionaldehyde is a precursor in the synthesis of N,N,β-Trimethyl-phenethylamine Hydrochloride (T796625).
Definition
ChEBI: 2-phenylpropanal is a member of the class of phenylacetaldehydes that is phenylacetaldehyde in which a hydrogen alpha to the aldehyde carbonyl group has been replaced by a methyl group. The major species at pH 7.3.
Production Methods
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 ℃.
Preparation
By alkaline condensation of acetophenone and ethyl chloroacetate; also by distillation of methylphenyl ethylene glycol in 91% yields (under atmospheric pressure).

General Description
2-Phenylpropionaldehyde is used in perfumes for its green hyacinth odor.
Flammability and Explosibility
Non flammable
Trade name
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.]
