The results of the research are mentioned below by dividing into three categories, that is, (1) the. pore size control of mesoporous molecular sieve MCM-41, (2) the acidity control of aluminosilicate MCM-41, and (3) the change of homogeneous catalysis into heterogeneous one for syntheses of fine chemicals catalyzed by acid.On (1) : The effect of auxiliary chemicals on pore size of MCM-41 was examined. Alkylbenzenes except triisopropylbenzene enlarge the pore size up to 11 nm. However, the structural regularity decreased very much. On the other hand, alkanes enlarge the pore size with keeping the structural regularity, but the increase in pore size is only 1 nm.On (2) : The acidity varies very much by changing preparation methods of aluminosilicate MCM-41. Aluminosilicate MCM-41 catalysts prepared without any metal cations exhibit high activities for acid catalyzed reactions.On (3) : As fine chemicals syntheses, Diels-Alder reaction by using various reactants, synthesis of di-t-butylperoxide from t-butyl alcohol and t-butylhydroperoxide, and bisphenol F synthesis from phenol and formalin were carried out. Acidity-controlled aluminosilicate MCM-41 catalysts exhibit very high activity for very reaction.

研究结果将在下面分为三类，即（1）。介孔分子筛MCM-41，（2）铝硅酸盐MCM-41的酸度控制的孔径控制，以及（3）（3）（3）将均质催化变为异质化学物质的酸合成的酸性化学物质的合成（1）：酸化化学物质的合成（1）：Auxiliary Chemicals对MCM-41的影响。烷基苯甲酸除三异丙基苯基外，孔尺寸升高到11 nm。但是，结构规律性降低了很大。另一方面，烷烃通过保持结构规律性扩大孔径，但是孔径的增加仅为1 nm.on（2）：酸度通过改变铝硅酸盐MCM-41的制备方法而变化很大。铝硅酸盐MCM-41催化剂在没有任何金属阳离子的情况下制备的催化剂表现出较高的酸催化反应活性。酸度控制的铝硅酸盐MCM-41催化剂表现出很高的反应活性。
