<P>PROBLEM TO BE SOLVED: To provide zeolite having an MFI type structure in which each amount of Al causing a strong acid point and nest silanol causing a weak acid point is precisely controlled, and a method for producing the zeolite; to put it concretely, to provide zeolite having an MFI type structure in which the mole ratio of SiO<SB POS="POST">2</SB>/Al<SB POS="POST">2</SB>O<SB POS="POST">3</SB>is 5,000-100,000, and the peak area at 3,500±50 cm<SP POS="POST">-1</SP>in infrared spectroscopic spectrum is 2-70 KMcm<SP POS="POST">-1</SP>, and a method for producing the zeolite. <P>SOLUTION: This invention relates: to zeolite having an MFI type structure in which the mole ratio of SiO<SB POS="POST">2</SB>/Al<SB POS="POST">2</SB>O<SB POS="POST">3</SB>is 5,000-100,000, and the peak area at 3,500±50 cm<SP POS="POST">-1</SP>in infrared spectroscopic spectrum is 2-70 KMcm<SP POS="POST">-1</SP>; and to a method for producing the zeolite. <P>COPYRIGHT: (C)2013,JPO&INPIT |
