From the data of infrared spectra of zeolite HZSM-5 synthesized in the picture. Schedule and identity can confirm the crystal structure of the band ZSM-5 vibration of bonding position directly to the structure of the standard HZSM-5.The position of the bar by vibration of double five ring of pentasil of ZSM-5 that wave number about 537 cm-1 bar vibration internal. Asymmetric stretching of T-O-T of zeolite. When T = Si or Al position, about 1 wave number070-1 090 780-792, and cm-1 and bar vibration O-H stretching of H2O O-H stretching silane and the digital of zeolite, wave number approximately 3 650 3 450 cm-1, and,, Respectively, the aluminum content that removed at different concentrations and 1.0 2.0 M no difference of infrared spectra significantly. The crystallinity of ZSM-5 considering the intensity of energy band T-O-T found that both catalyst concentration. Comparable.
