Zusammenfassung: | PCT No. PCT/NO97/00075 Sec. 371 Date Apr. 12, 1999 Sec. 102(e) Date Apr. 12, 1999 PCT Filed Mar. 12, 1997 PCT Pub. No. WO97/33692 PCT Pub. Date Sep. 18, 1997Microporous crystalline metallophosphate composition having an essential framework structure identified by the characteristic X-ray powder diffraction reflections given in Table I, and whose chemical composition in the calcined anhydrous form expressed in terms of mole ratios of oxides is: (MxAlyPz)O2 where M is silicon, x+y+z=1, and where 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. The invention also describes a method for preparing the products from a reaction mixture which includes both monovalent cations and fluoride. |
