Thermal isomerization of alpha-pinene in supercritical solvents, viz., ethanol, methanol, and propan-1-ol, was carried out, and differences in the rate and selectivity of the process were revealed. In supercritical ethanol the reaction rate increases sharply and the selectivity remains unchanged with an increase in the temperature (from 290 to 390 degrees C) or pressure (from 90 to 270 atm). The main reaction products are limonene, isomeric alloocimenes, and pyronenes. The selectivity for limonene in propan-1-ol is higher than in other alcohols when the conversion of alpha-pinene not higher than 50%. In supercritical ethanol (430 degrees C, 120 atm, 140 s) limonene is more stable than alpha-pinene (conversion 8%).
