<P>PROBLEM TO BE SOLVED: To provide a method for synthesizing a mesoporous material excellent in solid acidity, heat resistance, activity or others. <P>SOLUTION: A mixture for synthesizing the alumina-containing mesoporous material comprises a mixture of (1) a silica source, (2) an alumina source, (3) an alkali source, (4) a surfactant, (5) water, and the mixture in which when the amount of SiO<SB POS="POST">2</SB>of the silica source is 1 mol, (2) the molar ratio of the Al<SB POS="POST">2</SB>O<SB POS="POST">3</SB>of the alumina source, (3) the molar ratio of the M<SB POS="POST">2</SB>O of the alkali source, (4) the molar ratio of the surfactant are respectively Al<SB POS="POST">2</SB>O<SB POS="POST">3</SB>/SiO<SB POS="POST">2</SB>=0.005 to 0.05, the surfactant/SiO<SB POS="POST">2</SB>=0.05 to 0.3, M<SB POS="POST">2</SB>O/SiO<SB POS="POST">2</SB>=0.1 to 1.0, H<SB POS="POST">2</SB>O/SiO<SB POS="POST">2</SB>=20 to 100 (here, in M<SB POS="POST">2</SB>O the alkali source is shown in an oxide form, M is at least one selected from Na, K, NH<SB POS="POST">4</SB>), is subjected to hydrothermal processing at 80 to 160°C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
