Patent ID: 7824658

Claim:
A method for preparing a crystalline molecular sieve having MTT framework topology and having crystallite sizes in the range of about 150 to about 600 Angstroms, said method comprising: a. preparing a reaction mixture comprising, in terms of mole ratios, the following: 1) YO 2 /W 2 O 3 30-40 2) R + /YO 2 0.06-0.12 3) OH − /YO 2 0.20-0.26 4) K + /YO 2 0.09-0.15 5) and an amount of water not substantially in excess of the amount required to cause and maintain crystallization, wherein Y is silicon, germanium or mixtures thereof; W is aluminum, boron, gallium, iron or mixtures thereof; and R + is a diisopropylimidazolium cation; and b. heating said reaction mixture at crystallization conditions and in the absence of an external liquid phase for sufficient time to form a crystallized material containing crystals of a molecular sieve having MTT framework topology and having crystallite sizes in the range of about 150 to about 600 Angstroms.
