摘要
Zeolite ZSM-5 has been synthesized with the organosilicon compound γ-aminopropyl triethoxylsilane as structure-directing agent using the composition 10SiO2: Al2O3: 3-5Na2O: 0. 1-0.5R: 40-100H2O(molar ratios). First of all, γ-aminopropyl triethoxylsilane was quaternarized with bromoethane and ethyl alcohol. XRD, TG, DTA and SEM were used to characterize the sample. The investigation proves that the organosilicon compound resides intact at the channel intersections, and that the silicon atom In this species is located in a framework position. Prehydrolysis of the organosilane precursor is necessary for zeolite formation.
