Isobutyl Isobutyrate Usage And Synthesis


Chemical Properties

Isobutyl Isobutyrate is a volatile aroma component of fruit and honey. It is a colorless liquid with a strong, sweet odor reminiscent of honey. Small amounts are used in flower perfumes and in fruit flavors.

Chemical Properties

Ethyl phenylacetate has a pleasant, strong, sweet odor suggestive of honey and a bittersweet flavor.

Chemical Properties

clear colourless to pale yellowish liquid

Occurrence

Reported found in grapefruit juice, apple juice, figs, guava, pineapple, papaya, cognac, cider, grape wines and port wine.

Uses

In perfumery.

Preparation

By heating at the boil phenylacetonitrile and sulfuric acid in alcohol solution; by esterification of the acid catalyzed by HCl or H2SO4

Aroma threshold values

Detection: 650 ppb

Taste threshold values

Taste characteristics at 10 ppm: sweet, fruity, honey, cocoa, apple and woody

Safety Profile

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

Purification Methods

Shake the ester with saturated aqueous Na2CO3 (three times), aqueous 50% CaCl2 (twice) and saturated aqueous NaCl (twice). Dry with CaCl2 and distil it under reduced pressure. [Beilstein 9 H 434, 9 IV 1618.]
