α-Pinene gives a good yield of camphene over Ti02 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 Ti02 is present as anatase and IR shows that acidity is mostly of the Bronsted type. The specific surface of ca. 400 m2/g is mostly due to micropores. The average pore radius is 20 Å. This may have an effect on selectivity.
