ACETOACETIC ACID ISOAMYL ESTER Usage And Synthesis

Description

Isoamyl acetoacetate has an ethereal, sweet, winey odor and a green-apple flavor. May be prepared by transesterification of ethyl acetylacetate with isoamyl alcohol in the presence of sodium.

Chemical Properties

Colorless Iiauid. almost insoluble in water, soluble in alcohol, flavor materials. Isoamyl acetoacetate has an ethereal, sweet, winy odor; green-apple flavor.

Uses

ACETOACETIC ACID ISOAMYL ESTER is a synthetic flavoring agent that is a stable, colorless liquid of light green leaf-fruity odor. It should be stored in glass or tin containers. It is used in currant and berry flavors for applications in beverages, candy, and ice cream at 5–15 ppm. Finds some use in flavor compositions, mainly in apple and fruity flavor types. Concentration up to 25 ppm in the finished product (mostly candy).

Preparation

By transesterification of ethyl acetylacetate with isoamyl alcohol in the presence of sodium.

Definition

ChEBI: 3-Methylbutyl 3-oxobutanoate is an oxo carboxylic acid.
