FEMA 2811 Usage And Synthesis

Description

Octyl octanoate has a faint, fatty odor reminiscent of green tea with an oily, fruity, sweet, mildly green taste. May be prepared by esterification of octanoic acid with octyl alcohol in the presence of HCl catalyst; or by passing vapors of octanoic acid and hydrogen over a copper chromium oxide catalyst at high temperature (320°C).

Chemical Properties

Octyl octanate has a faint, fatty odor reminiscent of green tea and an oily, fruity, sweet, mildly green taste.

Uses

FEMA 2811 finds limited use in flavor compositions, mainly in Citrus complexes, Cherry, Grape, Pineapple, Plum and other fruit imitation flavors. The concentration is normally about 0.5 to 2 ppm in the finished product.
