Title:
新規ゼオライト
Document Type and Number:
Japanese Patent JP6672849
Kind Code:
B2
Abstract:
An object of the present invention is to provide an AFX zeolite having a novel structure. An AFX zeolite having a lattice spacing d of a (004) plane being not less than 4.84 Å and not greater than 5.00 Å, and a molar ratio of silica to alumina being not less than 10 and not higher than 32. Such an AFX zeolite can be produced by a production method comprising a crystallization step of crystallizing a composition at a temperature of not lower than 160°C; the composition containing a silicon source, an aluminum source, a 1,3-di(1-adamantyl)imidazolium cation, and an alkali metal; a molar ratio of hydroxide ions to silica being less than 0.25 or a molar ratio of silica to alumina being not higher than 27; and a molar ratio of the 1,3-di(1-adamantyl)imidazolium cation to silica being less than 0.20.
