Вхождение

Has apparently not been reported to occur in nature.

Использование

Allyl Cinnamate is a synthetic flavoring agent that is a fairly stable, hazy, colorless to light yellow colored liquid of cherry odor. it is used for its cherry note in flavors and has application in baked goods and candies at 1–2 ppm.

Методы производства

Allyl cinnamate is produced by the direct esterification of allyl alcohol with cinnamic acid.

Подготовка

By esterification of cinnamic acid with allyl alcohol in the presence of concentrated H2SO4.

Профиль безопасности

Moderately toxic by ingestion. Human skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALLYL COMPOUNDS and ESTERS

Метаболизм

Many esters, including benzyl cinnamate, are rapidly hydrolysed in vivo. Cinnamic acid is known to conjugate with glycine in the animal body, or it may be converted to benzoic acid(Williams, 1959). In the rabbit, cinnamic acid is almost entirely excreted as hippuric acid, without formation of cinnamoyl glycine(El Masry, Smith & Williams, 1956) . In the dog, Quick(1928) observed a large excretion of glucuronide, probably benzoylglucuronide. Dakin (1909) named B-phenyl-B-oxopropionic acid, cinnamoyl glycine and acetophenone as minor metabolites in the dog.

Растворимость в органика

Allyl Cinnamate is soluble in alcohol and oils, almost insoluble in Propylene glycol.
