Abstract: The pure Manganese Aluminophosphate molecular sieve was synthesized. The structure of Manganese Aluminophosphate molecular sieve MnAPO-5 wasinvestigated by means of X-ray diffraction, electron paramagnetic resonance Spectrum, infrared spectra and electron probe energy dispersion analysis. The results of infrared spectra and parameters of the unite cell show that the struct-ureof MnAPO-5 is of the AlPO4-5 type. The study of EPR, electron probe energy dispersion analysis and chemical composition of MnAPO-5 indicate that manganese enter into the framework of MnAPO-5 molecular sieve. The adsorption properties, thermal stability and surface acidity were investigated.The results show that MnAPO-5 has excellent physical and chemical properties.
