This invention relates to a method for synthesizing a new synthetic composition of ultra-large pore crystalline material which can be used as a sorbent or catalyst component for conversion of organic and inorganic compounds. The crystalline material product of this method exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C., a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units.
A method for synthesizing a composition of matter comprising an inorganic, porous crystalline phase material having, after calcination, a hexagonal arrangement of uniformly-sized pores having diameters of at least about 13 Angstrom Units and exhibiting a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units, which comprises (i) preparing a mixture capable of forming said composition, said mixture comprising sources of one or a combination of oxides selected from the group consisting of divalent element W, trivalent element X, tetravalent element Y and pentavalent element Z, an organic (R) directing agent and solvent or solvent mixture, and having a composition, in terms of mole ratios, within the following ranges:
