SAPO-5 and SAPO-11 were synthesized using aluminium isopropoxide and tetraethyl orthosilicate as source materials for aluminium and silicon, respectively, adopting a modified procedure. The as-synthesized materials were characterized by XRD and chemical analysis. Acidity was found by temperature-programmed desorption using TGA. Unit cell parameters were calculated for both as-synthesized and calcined materials. The catalytic activity of SAPO-5 and SAPO-11 in camphene isomerization was studied and selective formation of tricyclene was achieved.
