英文摘要	the zeolite synthesis was carried out using hexamethyleneimine (hmi) and cyclohexylamine (cha) binary amines as templates. the product is always mcm-22 under the conditions of sio2/al2o3 molar ratio of 30, na2o:h2o: (hmi + cha):sio2 molar ratio of 0.11:45:0.35:1, crystallization time of 84 h and crystallization temperature of 160 degrees c, even at a low hmi/cha molar ratio of 1/3. the presence of cha significantly enhances the relative crystallinity of mcm-22 at hmi/cha ratios less than 1. however, cha is an effective template to direct the formation of zsm-35 crystals when it was used alone. c-13 mas nmr spectra of hmi show some significant difference between the as-made mcm-22 samples obtained from the single hmi template matrix and the hmi-cha binary amine template matrix. it is concluded that in the single hmi template system, hmi acts as a structure-directing agent as well as has a stabilizing effect on the pore structure in its protonized form; while in the hmi-cha binary amine template system, hmi only plays a structure-directing role, and cha stabilizes the framework of the mcm-22.
