摘要：NOVELTY - The invention relates to a MCM-48 molecular sieve preparing method, including the main steps of: firstly in turn placing silicon source, alkali source, template agent and water soluble fluorine salt in a vessel; then making hydrothermal crystallization reaction at 0.1MPa; and finally washing, drying and baking the resultant to obtain the target matter. As compared with existing techniques, its remarkable advantage is shortening the preparing cycle of the MCM-48 molecular sieve.
