7-OCTEN-2-OL, 2-METHYL-6-METHYLENE Chemical Properties,Usage,Production

Chemical Properties

It is a colorless liquid with a fresh, floral, slightly lime-like odor. Due to its conjugated double bonds, it tends to polymerize; polymerization can be suppressed by adding inhibitors (e.g., antioxidants such as BHT).
Myrcenol can be prepared by treating myrcene with diethylamine to give a mixture of geranyl- and neryldiethylamine. These compounds are hydrated with a dilute acid to the corresponding hydroxydiethylamines. Deamination tomyrcenol is effected by using a palladium–phosphine–cation complex as a catalyst.
Myrcenol is used in perfumery to obtain a lifting top note in citrus and lavender compositions. It is mainly important in the production of 4-(4-hydroxy-4- methylpentyl)-3-cyclohexenecarboxaldehyde.

Uses

Myrcenol is used in perfume compositions for “lift” and freshness in floral or citrusy and “light” compositions, including soap perfumes.

Preparation

By chlorination of Myrcene, followed by hydrolysis.

Definition
