CINNAMALDEHYDE DIETHYL ACETAL Usage And Synthesis

Aroma

Faint, but fresh-green, slightly spicy, oily-sweet odor. Taste is mild and oily-sweet, not nearly as sweet as the aldehyde.

Physical properties

Almost colorless oily liquid. B.P. 251°C. (very close to that of Cinnamic aldehyde). Sp.Gr. 0.98.
Practically insoluble in water, soluble in alcohol and oils.

Uses

CINNAMALDEHYDE DIETHYL ACETAL is used occasionally in perfume formulations as a modifier and "new" note in modern-aldehydic or spicy-fruity fragrance types.
Stable in soap, but does not contribute much "spice" odor and can not be considered a suitable substitute for the aldehyde.

Preparation

Cinnamaldehyde diethyl acetal is prepared by using cinnamaldehyde and triethyl orthoformate as raw materials, adding p-toluenesulfonic acid in absolute ethanol, and then heating and refluxing.
