What is FEMA 2871?

Chemical properties

CLEAR COLOURLESS LIQUID

Chemical properties

FEMA 2871 has been identified as a volatile aroma component of peppermint oils. The fruitiness of its odor is even more pronounced than that of the isobutyrate. It is used in small quantities for the same purposes as phenylethyl isobutyrate.

Chemical properties

Phenethyl isovalerate has a fruity (rose-like) odor and a bittersweet flavor, reminiscent of peach. It is not very stable.

Occurrence

Reported found in peppermint oil, spearmint oil, Scotch spearmint oil, beer, grape brandy, cognac, cider and lamb’s lettuce.

Preparation

By esterification of phenethyl alcohol with isovaleric acid.

Taste threshold values

Taste characteristics at 2 to 10 ppm: sweet, fruity, ripe pineapple with honey, berry and peachy nuances.

Flammability and Explosibility

Non flammable

Safety Profile

Mddly toxic by ingestion. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS

Synthesis

FEMA 2871 is prepared by azeotropic esteritication of Phenylethylalcohol with iso-Valerie acid.
