Promoter induced rapid synthesis of AIPO4-5 molecular sieve in non-aqueous media using hexamethyleneimine template

摘要

AlPO_4-5 have been synthesized from non-aqueous media using hexamethyleneimine template in presence of sodium ions. The results show that the sodium catalyses the nucleation and crystallization process of the formation of AIPO_4-5 molecular sieve. The material synthesized was characterized by XRD, SEM, carbon and nitrogen analysis, TG/DTA, FT-IR, ~(27)Al and ~(31)P MASNMR. The results show that the samples are highly crystalline. The presence of octahedral and tetrahedral sites are observed in ~(27)A1 MASNMR, ~(31)P MASNMR gives only a single peak for tctrahedral phosphorous atoms.
