2-(2,6-dimethylhepta-1,5-dienyl)-4-methyl-1,3-dioxolane Chemical Properties,Usage,Production
Aroma
2-(2,6-dimethylhepta-1,5-dienyl)-4-methyl-1,3-dioxolane has very pleasant, sweet-citrus lemon-orangelike odor, mild, oily and somewhat green. Pleasant, but rather weak lemony taste in aqueous media (the decomposition changes the flavor to lemon). This acetal has been suggested for use in flavor compositions, but its instability presents a drawback, particularly since the purpose of using the acetal was to introduce a diflrren: and modifying flavor note - not the Citral note.
Chemical Properties
Citral propylene glycol acetal has a sweet, citrus, lemon–orange odor; mild, lemony flavor changing to a lemon flavor in aqueous media.
Physical properties
Colorless oily liquid. Slightly soluble in water, soluble in alcohol and oils. The material shows slight decomposition when dissolved in water. It is also soluble in Propylene glycol.
Preparation
Condensation of citral with propylene glycol using a catalyst.
Definition
ChEBI: Citral propylene glycol acetal is a dioxolane.
