ABSTRACT:
The present invention relates to a process for preparing zeolites having the MTT crystal structure, such as zeolites SSZ-32 and ZSM-23, using small, neutral amines capable of forming the zeolite, the amine containing (a) only carbon, nitrogen and hydrogen atoms, (b) one primary, secondary or tertiary, but not quaternary, amino group, and (c) a tertiary nitrogen atom, at least one tertiary carbon atom, or a nitrogen atom bonded directly to at least one secondary carbon atom (such as isobutylamine, diisobutylamine, diisopropylamine or trimethylamine), wherein the process is conducted in the absence of a quaternary ammonium compound.
