Microporous crystalline metallophosphate composition having an essential framework structure whose chemical composition in the as synthesised form expressed in terms of mole rations of oxides is: mR(MxAlyPz)O2 where M is silicon, x+y+z=1, m may have a value from 0.02 to 0.3, R is at least one templating agent, x, y and z represent the mole fractions of silicon, aluminium and phosphorous present in the product, and where x may have a value from 0 to 0.5, y may have a value from 0.25 to 0.5 and z may have a value from 0.25 to 0.5, and where one reactive form of fluoride may be present in an effective amount to form the product, and having a characteristic X-ray powder diffraction pattern containing at least the d-spacings as set forth in Table I.
L'invention concerne une composition de métallophosphates cristallins microporeux ayant une infrastructure dont la composition chimique, sous la forme synthétisée exprimée en termes de rapports molaires entre oxydes, est: mR(M¿x?Al¿y?P¿z?)O¿2? où M représente silicium, x+y+z=1, m peut valoir 0,02 à 0,3, R est au moins un agent de matriçage, x, y et z représentent les fractions molaires de silicium, aluminium et phosphore présentes dans le produit; y peut valoir 0,25 à 0,5 et z peut valoir 0,25 à 0,5, une forme réactive de fluorure pouvant être présente en quantité suffisante pour former le produit. Ladite composition se caractérise par un spectre de diffraction de rayons X contenant au moins les espacements d conformément au tableau I.
