Abstract:
By exchanging NaZSM-5 zeolite with KOH solution under heating,strongly basic KZSM-5 zeolites was obtained. The structure and basicity of KZSM-5 zeolites was studied by using IR, XRD, XPS and Hammett indicator non-aqueous titration..The catalytic property was studied on the reaction of onestep synthesis of mesityloxide from aldol condensation of acetone. The catalytic activity could be well related with the basicity of catlysts.
