ABSTRACT:
This invention relates to a method for preparing large pore synthetic crystalline molecular sieve composition which may contain framework +3 valence element, e.g. aluminum, and one or more of a) +4 valence element, e.g. silicon, and b) +5 valence element, e.g. phosphorous. The method utilizes cyclohexylamine as directing agent in the forming mixture. The source of +3 valence element and, optionally +4 element is an alkoxide thereof, e.g., aluminum iso-propoxide. The resulting product may be used as a catalyst.
