| 英文摘要 | the pure zsm-35 zeolite was synthesized in a static hydrothermal system at 220 degrees c using cyclohexylamine as the template and silica sol as the si source. when the initial gel contained a certain amount of k(+), the mutual role of k(+) and na(+) inhibited the formation of mordenite, and well crystallized product was formed with n(k(+))/n(k(+)+na(+)) = 0.3. optimum regions of the synthetic conditions of zsm-35 zeolite obtained by x-ray diffraction were n(m(2)o)/n(al(2)o(3)) = 3.2-3.4 and n(sio(2))/n(al(2)o(3)) = 22. the building units in the precursor were identified as five-membered and six-membered silicate rings by uv-raman spectroscopy. the intensity of the raman band at 450 cm(-1) increased in the beginning of crystallization, and the new bands at 421, 312, and 215 cm(-1) appeared with consuming the amorphous gel, indicating that the ring species were turned out to be aggregate through the hydrothermal treatment, and finally formed zsm-35 zeolite. the strong raman band at 421 cm(-1) should be assigned to the bending vibration of the five-membered silicate ring, and the raman band at 312 cm(-1) might correspond to the six-membered silicate ring of zsm-35 zeolite framework. |
