Synthesis of ZSM-5 Zeolite Using γ-Aminopropyl Triethoxylsilane as Structure-directing Agents

Abstract

Abstract: 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, DTAand SEMwere 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.

Key words: Zeolite synthesis, Structure-directing agent, Organosilicon compound, ZSM-5, γ-Amino- propyl triethoxylsilane
