Kind Code:
A
Abstract:
A method for synthesizing a large pore crystalline molecular sieve having an X-ray diffraction pattern with the characteristic lines (IA) comprises (i) preparing a mixture comprising sources of oxides of aluminum, phosphorus, and optionally one or more elements (M) other than aluminum or phosphorus, water and a directing agent (DA), and having a composition, in terms of mole ratios, within the following ranges: M/Al2O3 0 to 0.5; P2O5/Al2O3 0.5 to 1.25; H2O/Al2O3 10 to 100; DA/Al2O3 0.5 to 1.5; wherein DA is a compound of formula (I), wherein R, R', R'' and R''' are the same or different and are selected from -CH2X, -CH2CH2X, and X is a cation, (ii) maintaining said mixture under conditions including a temperature of 100 DEG C to 145 DEG C for a period of time of up to 80 hours and (iii) recovering the crystalline product from step (ii).
