ACETOACETIC ACID N-HEPTYL ESTER Usage And Synthesis

Aroma

Pleasant, oily-green, rich and sweet odor with vinous undertone and moderate tenacity.

Uses in Perfume

Acetoacetic acid N-heptyl ester has found use in perfume compositions, mainly in specialties and bases intended for topnote work in the Citrus and light-floral type. The ester is mrely sold under its proper chemical name, but it enters a number of very useful bases of fresh, greencilrusy character and unusual power.
It performs very well with the equally clandestine Hydroxycaproic aldehydcs and related aldehydes, acctals, etc. and it can be used with or without Citral - it gives a lemony effect if there are lemony materials present to be enhanced, while it has a similar lifting effect upon Bergamot and other Citrus oils. Light florals, such as Muguet and Freesia or the more imaginary waterlily type may also benefit from traces of the title aldehyde or compositions made thereof.

Physical properties

Colorless, oily liquid. Insoluble in water, soluble in alcohol and oils.

Production Methods

Acetoacetic acid N-heptyl ester can be produced from Heptanol and Diketen.
