3,7-DIMETHYL-1-OCTEN-3-OL Chemical Properties,Usage,Production

Aroma

3,7-Dimethyl-6-octen-3-ol has comparatively powerful, fresh-floral, citrusy (with emphasis on Lime) and diffusive odor. Less woody than LinaIooI, more powerful and more Lime-like than Tetrahydro Iinalool.

Physical properties

Colorless oily liquid. Sp.Gr. 0.86. B.P. 201°C. Very slightly soluble in water, soluble in alcohol, Propylene glycol and oils.

Uses

3,7-Dimethyl-6-octen-3-ol is an excellent perfume material for freshfloral fragrance types, as a modifier in Lime and Lime-floral complexes, as a blender in modern soap perfume compositions. More versatile than Linalool and Tetrahydrolinalool, but not quite as discrete as the latter.

Production Methods

3,7-Dimethyl-6-octen-3-ol can be produced by catalytic, partial hydrogenation of Linalool.
