A MoO3 catalyst for the transesterification of phenyl acetate and dimethyl carbonate to diphenyl carbonate was prepared by calcination. The MoO3 calcined at 400 or 500 oC was an excellent catalyst, and it can be reused many times and regenerated simply by calcination while maintaining catalytic activity almost as high as the fresh sample.

The precursor structure plays a unique role in determining the interdispersion and the activity of the final catalysts. It is also evident that aging time influenced the precursor morphology. During the aging time, the composition and structure of the precursors changed obviously after the color transition point.

This review describes the novel organotemplate-free routes for synthesizing zeolites with the emphasis on ZSM-5, β, ZSM-34, ECR-1, etc., which normally require the presence of organotemplates in the synthesis. The new routes are of great potential industrial applications because of the low cost, energy saving, emission reduction, and consequent huge economic benefits.
