A series of Clinoptilolite/NaY/MCM-41 composites were synthesized through a two-step crystallization
process consisting of in situ crystallization of NaY on Clinoptiololite as a starting materials and the
overgrowth of MCM-41 on the surface of Clinoptiololite/NaY composite. The composites synthesized were
characterized by means of XRD, TGA, differential thermal analysis DTA and IR spectra.XRD analysis
showed that the triple composite obtained in the present investigation possess the typical characteristics of
well-ordered mesoporous MCM-41 and NaY zeolite .The results of DTA indicated that
cetyltrimethylammoniumbromide attached on the NaY phase this composite can be used for intermolecular
acylation
