Chemische Eigenschaften
Benzyl Cinnamate occurs in
balsams and balsam oils. It forms white, sweet-balsamic-smelling crystals (mp
35-36°C). Benzyl cinnamate is used as a fixative in perfumes and as a component
of heavy, oriental perfumes.
Occurrence
Reported found in Peru and Tolu balsam, in Sumatra and Penang benzoin, and as the main constituent of
copaiba balsam.
Verwenden
Benzyl cinnamate has been employed as internal standard during the determination of compounds commonly added to personal care products such as UV filters and antimicrobial agents in environmental samples.
synthetische
By heating benzyl chloride and excess sodium cinnamate in water to 100 to 115°C; by heating sodium cinnamate with an
excess of benzyl chloride in the presence of diethylamine.
Vorbereitung Methode
Benzyl cinnamate is produced by the direct esterification of
benzyl alcohol with cinnamic acid.
Allgemeine Beschreibung
Benzyl cinnamate is widely used as a fragrance ingredient.
Hazard
Moderately toxic.
Sicherheitsprofil
Moderately toxic by ingestion. Amild allergen and skin irritant. Combustible liquid. When heated to decomposition it emits acridsmoke and irritating fumes.
Stoffwechsel
See monograph on Benzyl alcohol (p. 1011).
l?uterung methode
Recrystallise the ester to a constant melting point from 95% EtOH. It has the odour of balsam. Alternatively dissolve it in Et2O, wash it with 10% aqueous Na2CO3, H2O, dry (Na2SO4), evaporate and fractionate it under reduced pressure using a short Vigreux column (p 11). It decomposes when boiled at atmospheric pressure. [Eliel & Anderson J Am Chem Soc 74 547 1952, Bender & Zerner J Am Chem Soc 84 2550 1962, Beilstein 9 IV 2012.]
