Abstract
A process is disclosed for producing small crystal, high surface area crystalline materials having the MFI and/or MEL framework-type, designated as EMM-30, using as a structure directing agent tetrabutylammonium cations and/or tetrabutylphosphonium cations, or 1,5-bis(N-tributylammonium)pentane dications, and/or 1,6-bis(N-tributylammonium)hexane dications. The compositions made according to that process, as well as the various dication compositions themselves, are also disclosed.
