1,1-Dimethoxy-3,7-dimethylocta-2,6-diene Chemical Properties,Uses,Production

Description

Citral dimethyl acetal is a colorless liquid. Sp.Gr. 0.89. B.P. slightly lower than that of Citral. Almost insoluble in water, soluble in alcohol and oils.

Chemical Properties

Citral dimethyl acetal has a fresh, lemon-like odor. The commercial product consists of a mixture of cis- and trans-isomers.

Occurrence

Apparently has not been reported to occur in nature.

Uses

Citral dimethyl acetal is used in perfume compositions partly as a mild-green topnote in soap fragrances, and also as a topnote modifier in delicate floral fragrances, green-citrusy types, fresh notes, etc. Used in flavor compositions mainly in Citrus types and generally in fruit flavors to introduce a natural freshness similar to that of unripe fruit or green Lemon peel, Apple peel, etc.

Preparation

From citral and methyl alcohol in the presence of a catalyst, or by reacting citral with trimethyl orthoformate.

Definition

ChEBI: A monoterpenoid that is the acetal obtained by formal condensation of citral with methanol.

Taste threshold values

Taste characteristics at 10 ppm: green, citrus, lemon, grapefruit, lime with woody and terpy nuance.
