| Abstract: The molecular sieves SAPO-5 and SAPO-34 have been synthesized hydrothermally in the presence of triethylamine templates in non-acid medium. The determination X-ray diffraction, electron scanning microscope, X-ray photoelectron spectroscopy, infrared spectrum showed the difference of the two kinds of silicoaluminophosphate molecular sieves. Some properties, including thermal stability, surface acidity and adsorption property, have been studied. |
| Keywords: molecular sieve silicoaluminophosphate triethylamine non-acid medium |
