    • The synthetic porous crystalline material, MCM-56, is synthesized by a process comprising the steps of: a) preparing a reaction mixture containing sources of alkali or alkaline earth metal (M) cation, an oxide of an trivalent element X, an oxide of a tetravalent element Y containing at least 30 wt. % of solid YO.sub.2, a directing agent (R), and water, said reaction mixture having a composition, in terms of mole ratios of oxides, within the following ranges: YO.sub.2 /X.sub.2 O.sub.3 5 to 35 H.sub.2 O/YO.sub.2 10 to 70 OH.sup.-- /YO.sub.2 0.05 to 0.5 M/YO.sub.2 0.05 to 3.0 R/YO.sub.2 0.1 to 1.0 b) crystallizing said mixture at a temperature of about 80.degree. C. to about 225.degree. C., preferably about 125.degree. C. to about 140.degree. C., to form crystals of MCM-56, c) terminating said crystallization prior to the formation of a significant quantity of MCM-49, and d) separating the MCM-56 crystals from the reaction mixture.
    • 合成多孔结晶材料MCM-56通过包括以下步骤的方法合成:a)制备含有碱金属或碱土金属(M)阳离子,三价元素X的氧化物, 含有至少30重量%的四价元素Y。 %的固体YO 2,导向剂(R)和水,所述反应混合物的组成按照氧化物的摩尔比在以下范围内:YO 2 / X 2 O 3 5至35H 2 O / YO 2 10至70 OH- / YO2 0.05〜0.5M / YO2 0.05〜3.0R / YO2 0.1〜1.0 b)在约80℃至约225℃,优选约125℃至约140℃的温度下使所述混合物结晶, 以形成MCM-56的晶体,c)在形成显着量的MCM-49之前终止所述结晶,以及d)从反应混合物中分离MCM-56晶体。
