    摘要： A crystalline aluminosilicate (which may contain ftuorine) has in its X-ray diffraction pattern seven diffraction lines showing the following relative intensities at the positions of the following respective diffraction angles (2θ):

    Such crystalline aluminosilicates are produced as relatively large crystals by carrying out a hydrothermal synthetic reaction in the presence of a fluorine compound.
    The crystalline aluminosilicates can be used as an adsorbent for the separation of various compounds, for example. the isomers of hydrocarbons, or can be converted to a solid acid by treatment with an acid such as hydrochloric acid and be used as catalysts for various reactions, for example, the preparation of olefins from methanol or dimethyl ether by the dehydration reaction.
