Abstract: SAPO-5 molecular sieves have been synthesized in the presence of HF and tripro-pylamine as template. The substitute routes was investigated by ~(31)P and ~(29)Si MAS NMR, electron probe microanalysis and XPS technique, which suggested that there is no P—O—Si linkage in the framework. The substitution can occur via (1) silicon substitution for phoshorus and (2) simultaneous substitution of two silicon for one aluminium and one phosphorus. The framework of SAPO-5 consists of phospho-aluminosilicate and aluminosilicate.
