1,1-Diethoxy-3,7-dimethylocta-2,6-diene Usage And Synthesis

Chemical Properties

colourless liquid

Chemical Properties

Citral Diethyl Acetal is a colorless liquid with a floral, warm, woody citrus odor. It is relatively stable in alkali and can, therefore, be used in soap.

Chemical Properties

Citral diethyl acetal has a mild, green, citrus odor and a green, oily, citrus-peel flavor.

Uses

Since Citral Diethyl Acetal is stable in soap, it can be used in such fraBances, but should not be considered anything near a substitute for Citral as an odor. Used in flavor compositions, mainly in Citrus flavors along with natural oils and synthetic flavor chemicals. It will introduce quite natural green-oily, “peel” notes in Lemon and Lime, and it can be twisted into an Orange with the proper background materials. Concentration in the finished product is usually about 100 ppm in condiments, (lower in other products).

Preparation

From ethyl orthoformate and citral.

Definition

ChEBI: 1,1-Diethoxy-3,7-dimethyl-2,6-octadiene is a monoterpenoid.

Taste threshold values

Taste characteristics at 10 ppm: green, citrus lemon with waxy nuance.

General Description

Clear colorless liquid.

Air & Water Reactions

1,1-Diethoxy-3,7-dimethylocta-2,6-diene may be sensitive to prolonged exposure to moisture. Insoluble in water.

Reactivity Profile

1,1-Diethoxy-3,7-dimethylocta-2,6-diene may be sensitive to prolonged exposure to moisture. 1,1-Diethoxy-3,7-dimethylocta-2,6-diene will decompose on heating.

Fire Hazard

Flash point data for 1,1-Diethoxy-3,7-dimethylocta-2,6-diene are not available. 1,1-Diethoxy-3,7-dimethylocta-2,6-diene is probably combustible.
