Appearance

Colorless liquid.

Solubility

Practically insoluble in water, soluble in alcohol and oils.

Odor

Powerful, balsamic-gassy, heavy and sweet, warm odor. Much less gassy and not nearly as diffusive as Styrene. Overall softer and very similar in odor characteristics.

Uses in perfumery

This epoxide is occasionally used in the composition of artificial essential oils, e.g. Styrax oil, where the Styrene effect must be extended deeper into the fragrance, and not be quite as volatile as it will be with Styrene itself.

Production

1) from Styrene with Perbenzoic acid. 2) from Styrene chlorohydrin with Sodium hydroxide.
