CATALYTIC ACTIVITIES OF ALKALINE EARTH METAL OXIDES FOR ISOMERIZATIONS OF 2-PINENE AND 2(10)-PINENE
The isomerization of 2-pinene or 2(10)-pinene over evacuated MgO, CaO, SrO and BaO catalysts was carried out at room temperature or 150°C. All catalysts were found to exhibit extremely high selectivities for the formation of 2(10)-pinene or 2-pinene. The highest activity was observed over SrO, where the isomerization took place at room temperature and attained its equilibrium in only 15 min.
