alpha-Pinene gives a good yield of camphene over TiO2 catalysts. The optimization of selectivity and yield depends on the level of acidity, activation time, activation temperature and other factors. Modelling of the kinetic system is performed by lumping species and using Langmuir-Hinshelwood kinetics. XRD shows that TiO2 is present as anatase and IR shows that acidity is mostly of the Bronsted type. The specific surface of ca. 400 m(2)/g is mostly due to micropores. The average pore radius is 20 Angstrom. This may have an effect on selectivity.
