ISOPULEGYL ACETATE Usage And Synthesis

Description

Isopulegyl acetate has a sweet, mint-like odor. Isopulegyl acetate may be synthesized by prolonged heating of citronellal with acetic anhydride (with or without sodium acetate).

Chemical Properties

CLEAR COLOURLESS LIQUID, Fresh, green-minty, leafy, sweet-fruity (unripe fruit) odor of moderate tenacity. The odor of the enol-acetate is sharper, more green, while the iso-Pulegyl acetate has a condiment-spicy character, sometimes almost Dill-pickle-like.

Uses

The title material is used in perfume compositions as a freshener in Rose, Geranium, Oriental, Lavender, Fougere, etc., particularly in soap where its powerful “lift” is appreciated. The ester is also used in flavor compositions, mainly Berry- and fruit types, at the rate of 5 to 25 ppm in the finished product.

Preparation

by cyclization of the Acetate (-enolacetate) obtained from Citronella] and Acetic anhydride. The enol-acetate is an intermediate in the process of making Isopulegyl acetate.
