 | Questions And Answer | Back Directory |  | [Description] 
 Propiophenone belongs to the family of acetophenones, which is present in some certain cheese, coffee and coffee products, tea and roasted nuts with sweet-smelling odor. It is wisely used as an intermediate in the preparation of other organic compounds, such as synthetic aryl alkenes, like cinnamic acids. It is also a useful intermediate for pharmaceuticals production, such as ephedrine, propiophenone derivatives (cathinone and methcathinone), and especially for the preparation of nervous system drugs (anxiolytic and hypnotic drugs). Besides, due to its naturally pleasant flowery odor, propiophenone can be used as a component in some perfumes.

 colourless to light yellow liquid
 |  | [Chemical Properties] 
 Propiophenone has a strong, flowery odor.
 |  | [Occurrence] 
 Reported found in coffee, roasted filberts, roasted peanuts and roasted green tea. Also reported found in
Camembert cheese, black tea, roasted macadamia nut, tamarind, dried bonito, cherimoya and sapodilla fruit.
 |  | [Uses] 
 In perfumery; in the synthesis of ephedrine and related Compounds.
 |  | [Uses]

 |  | [Uses] 
 Propiophenone is an aryl ketone used in the preparation of pharmaceutical and organic compounds. Propiophenone is used in perfumes as well as in the preparation of neurochemical compounds such as ephe
drines.
 |  | [Definition] 
 ChEBI: An aromatic ketone in which the two substituents on the carbonyl C atom are phenyl and ethyl.
 |  | [Production Methods] 
 Propiophenone is produced by the Friedel–Crafts acylation
of benzene with propionic acid chloride in the presence of
aluminum chloride. It may also be produced by the reaction
of benzoic acid and propionic acid using a calcium acetate–
aluminum oxide catalyst.
