摘要
以三乙胺为模板剂,用水热晶化法,首次在非酸性介质中合成了SAPO-5、SAPO-34型分子筛.通过X-射线粒未衍射、电子探针微区分析、电子能谱及红外光谱进行了结构研究,确认合成样品为SAPO-5和SAPO—34型分子筛,并对它们的化学组成、热稳定性、表面酸性及吸附性能进行了研究。
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.
