Patent

CA 2236075

The present invention relates to a process for preparing mesoporous crystalline material, in particular to a novel process for preparing crystalline material having mesoporous structure by dissolving silica in hydrogen fluoride solution and reacting it on the condition of atmosphere and room temperature for a short reaction time. As the result, the present invention provides a process to use all kinds of silica and to synthesize mesoporous material for a short reaction time.

La présente invention se rapporte à un procédé de préparation d'une matière cristalline mésoporeuse, et notamment à un nouveau procédé de préparation d'une matière cristalline ayant une structure mésoporeuse qui consiste à dissoudre de la silice dans une solution de fluorure d'hydrogène et à la faire réagir à température ambiante et dans des conditions atmosphériques normales pendant un court laps de temps. La présente invention se rapporte par conséquent à un procédé qui permet d'utiliser tout type de silice et de synthétiser la matière mésoporeuse au cours d'une réaction de courte durée.
