Appearance

Colorless oily liquid.

Solubility

Insoluble in water, soluble in alcohol and oils.

Odor

Fresh-fruity, sweet and moderately tenacious odor. The fruity notes are fresher, less floral than those of the n-Valerophenone.

Uses in perfumery

The title material has been suggested for use in perfume compositions. If it were available at a cost competitive to that of the large-volume soap-fragrance chemicals, it could undoubtedly find extensive use as a sweetener and modifier in many fragrance types, floral and non-floral. It is very stable in alkali, and compatible with most of the conventionally employed soap fragrance chemicals.

Production

1) from iso-Butyl phenylcarbinol by reduction. 2) from Benzonitrile plus iso-Butyl magnesium chloride, followed by hydration.
