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.
