Kinetics of 2-Pinanol Isomerization to Linalool on the Monolith Carbon-Containing Catalyst

Isomerization of 2-pinanol into linalool is studied on a monolith carbon-containing catalyst at 733–893 and a total pressure of 2–40 torr. The rate constants of cis(trans)-2-pinanol transformation into linalool and linalool cyclization are determined. Experimental data are described by the consecutive kinetic scheme. The mechanism of linalool formation is proposed according to which pinane ring opening occurs in an intramolecular reaction. A highly selective process of linalool synthesis by the thermal isomerization of 2-pinanol is shown to be possible.
