TRANS-2-HEXEN-1-AL DIETHYL ACETAL Chemical Properties,Usage,Production

Chemical Properties

(E)-2-Hexenal diethyl acetal has a “green” fruity odor

Uses

Suggested for use in perfume compositions, this acetal should not be considered as a variation of the aldehyde. It has its own odor and character, and since it is much milder, it is easier to apply to experimental perfumes. The greenness is not sharp and not typically leafy. It has a caramellic undertone resembling that found in Citral diethylacetal and other acetals. Once approved by the authorities for use in food flavors, this acetal could find use in various compositions, such as imitation GooseberrY, Apple, Wine, Grape, etc.

Definition

ChEBI: 1,1-Diethoxy-2-hexene is an acetal.

Synthesis

Trans-2-hexen-1-al diethyl acetal is prepared from trans-2-Hexenal and Ethanol by condensation.
