摘要：NOVELTY - The invention relates to a method for preparing meso-porous molecular sieve MCM-48, including the main steps of: firstly in turn placing silicon source, alkali source, template agent and water solublefluorine 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 that the prepared MCM-48 has good hydrothermal stability (i.e. pore canals does not collapse in 100 deg.C water for 72 hours), shortening the preparing cycle of the MCM-48 molecular sieve. Besides, the invention has the advantages of simple and easy-to-operate whole preparing process, excellent reaction repeatability, wide application range, etc.
