Appearance

Almost colorless liquid.

Solubility

Insoluble in water, poorly soluble in propylene glycol, soluble in alcohol and oils.

Odor

The odor resembles that of para-Methyl acetophenone, but is somewhat milder, more refined, subdued. The character is more woody-hay-like, warm and quite tenacious.

Uses in perfumery

This ketone has been suggested for use in perfume compositions to introduce herbaceous (or hay-like) notes in Mimosa, Violet, Lavender, Orris or versions of the 'New Mown Hay' type.

Production

Produced by several methods, e.g. from Benzene, Acetyl chloride, iso-Butyl chloride (or bromide) using Aluminium chloride catalyst in a Friedel-Craft type synthesis.
