Abstract: This work describes the preparation of SAPO-34 from a aluminophosphate lamelar analogue of kanemite structure, herein named ALPO-kan. The transformation occurs through a novel zeolitic silicoaluminophosphato named CAL-1 and was promoted by the addition of silica and hexamethyleneimine (HMl) as structure directing agent into a suspension of ALPO-kan. Calcination of CAL-1 affords H-SAPO-34-kan. The material was characterized by X-rays diffraction, scanning electronic microscopy, thermogravimetry, infrared spectroscopy in the hydroxyls region and Raman spectroscopy. The particles morphology is rather different from that of SAPO-34 prepared from a conventional gel synthesis and is composed of thin plates and pseudo-rombohedral particles that show remainings of a lamelar structure. This indicates that the transformation has occurred through a solid state reaction.
