Synthesis of Camphene by α-Pinene Isomerization Using W2O3–Al2O3 Catalysts


W2O3–Al2O3 catalysts prepared by “sol–gel” and impregnation methods were characterised by XRD, FTIR and nitrogen adsorption. Both catalysts were tested in the isomerization of α-pinene in a batch reactor at atmospheric pressure and 150 °C. Conversion of α-pinene and selectivity to camphene was superior for the “sol–gel” catalyst than that observed for the impregnated catalyst.
