ETHYL ACETOACETATE PROPYLENE GLYCOL KETAL Usage And Synthesis

Aroma

Fruity-floral and warm, sweet odor of good tenacity. The wincy-"fermented-fruit-like" undertones resemble the odor of Strawberry preserve.

Uses in Perfume

ETHYL ACETOACETATE PROPYLENE GLYCOL KETAL has found some use in perfume compositions where a certain deep-fruity note is desirable along with a floral complex. Jasmin, Tuberose, Gardenia and many other floral bases, spicy fragrances, etc. can achieve new and interesting "lifts" from this material, which has an overall effect resembling that of the alkyl-substituted Cyclopentenones and their homoiogues.

Physical properties

Colorless or pale straw-colored oily liquid. Insoluble in water, soluble in alcohol, miscible with oils.

Chemical Properties

ETHYL ACETOACETATE PROPYLENE GLYCOL KETAL is a colorless liquid with a fresh, fruity odor reminiscent of apples and strawberries. It is mainly used to create fresh, fruity top notes to floral fragrances.
Thematerial is available by reaction of ethyl acetoacetate with propane-1,2-diol.

Definition

ChEBI: Cis- and trans-Ethyl 2,4-dimethyl-1,3-dioxolane-2-acetate is a fatty acid ester.

Production Methods

ETHYL ACETOACETATE PROPYLENE GLYCOL KETAL can be produced from Propylene glycol and Ethyl acetoacetate. The latter acts as a ketone to condense with the glycol. The condcnsat ion is normally encouraged by a catalyst and carried out under conditions of azeotropic distillation.

Aroma threshold values

Medium strength odor, fruity type.

Trade name

Fraistone (IFF), Fragolane (Symrise)
