Beschreibung
4-(p-Hydroxyphenyl)-2-butanone has a sweet, fruity, raspberry
preserves odor. May be prepared by catalytic hydrogenation of phydroxy-benzylidene acetone in the presence of platinum black in
ether or methanol or in the presence of palladium absorbed on
charcoal.
Chemische Eigenschaften
4-(4-Hydroxyphenyl)-2-butanone is a highly characteristic component of raspberry aroma. It
forms colorless crystals (mp 82–83°C) with a sweet, fruity odor strongly reminiscent
of raspberries.
Raspberry ketone is prepared by alkali-catalyzed condensation of the alkali
salt of 4-hydroxybenzaldehyde and acetone, followed by selective hydrogenation
of the double bond in the resulting 4-hydroxybenzalacetone. Other syntheses
start from phenol, which is converted into 4-(4-hydroxyphenyl)-2-butanone with
methyl vinyl ketone or with 4-hydroxy-2-butanone.
Occurrence
Reported found European cranberry, raspberry, blackberry, loganberry and sea buckthorn (Hippophae rhamnoides L.).

Definition
ChEBI: A ketone that is 4-phenylbutan-2-one in which the phenyl ring is substituted at position 4 by a hydroxy group. It is found in a variety of fruits including raspberries, blackberries and cranberries, and is used in perfumery and cosmetics.
Sicherheitsprofil
Poison by intraperitoneal route. Moderately toxic by ingestion. Flammable liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also KETONES.
