[M]-CAL-2 (M = Mn, Co and Fe) are metallosilicoaluminophosphates ([M]-APSO) with chabazite-related structure, which are part of the CAL molecular sieves family. They were prepared with a recently developed synthesis based on the use of layered AlPO p

Normal-butylammonium lamellar aluminophosphate has been used as the source of aluminum and phosphorous atoms in the synthesis of CAL-4, a chabazite-like structure analogous to SAPO-44, in a reaction with silica and using cyclohexylamine as structure

Among the synthesis methods to prepare zeolites, the sol–gel processes are the ones most known and used. The same may be said about the aluminophosphate-based molecular sieves. This work reviews the preparation of zeolites from layered silicates an

The acidity of crystalline silicoaluminophosphates with chabazite-related structure (CHA), was studied by using CO and C2H4 probe molecules. SAPO-34 samples with similar silicon concentrations prepared using different structure-directing agents have

In this work, the synthesis of CAL-4, a SAPO-44 structural analogue, is studied. This silicoaluminophosphate molecular sieve was prepared starting from the layered aluminophosphate n-butylammonium-AlPO-kanemite with the addition of silica and cyclohe

CAL-4 is a member of a novel family of SAPOs, which can be prepared from the layered precursor n-butylammonium ALPO-kanemite (nBA ALPO-kan). The usage of a layered starting material was found to have a profound influence on product morphology, acid s

This study shows that SAPO-44 molecular sieve may be prepared from AlPO-kanemite as source of phosphorus and aluminum simultaneously, without contamination with other phases. The results showed that the rate of the reaction was dependent on the durat
