Zusammenfassung:The invention discloses a synthetic method of fine grain strong acid type ZSM-5 molecular sieve, which comprises the following steps: fetching silica dioxide and aluminum oxide; allocating mole ratio at 15-100, junior particle diameter at 0.01-0.5 mu m and surface area at 300-550m2/g; making silica source, aluminium source and inorganic acid as raw material; fore-treating through supersonic wave; hydrothermal blooming; filtering; exchanging; washing; filtering and drying under exciting seed or non-exciting seed condition; getting the product. The molecular sieve possess higher active, which can product cyclohexanol effectively.
