Benzyl cinnamate Usage And Synthesis

Chemical Properties

Clear colorless to yellowish crystalline mass or liquid after meltin

Chemical Properties

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.

Chemical Properties

Benzyl cinnamate has a sweet, balsamic odor and a honey-like taste.

Occurrence

Reported found in Peru and Tolu balsam, in Sumatra and Penang benzoin, and as the main constituent of copaiba balsam.

Uses

In artificial flavors, in perfumes, mainly as a fixative.

Production Methods

Benzyl cinnamate is produced by the direct esterification of benzyl alcohol with cinnamic acid.

Preparation

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.

Taste threshold values

Taste characteristics at 50 ppm: spicy, floral, fruity, balsamic.

Hazard

Moderately toxic.

Safety Profile

Moderately toxic by ingestion. Amild allergen and skin irritant. Combustible liquid. When heated to decomposition it emits acridsmoke and irritating fumes.

Metabolism

See monograph on Benzyl alcohol (p. 1011).

Purification Methods

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.]
