Title:
ゼオライトの製造方法及びε−カプロラクタムの製造方法
Document Type and Number:
Japanese Patent JP6544118
Kind Code:
B2
Abstract:
A method for producing zeolite and a method for producing -caprolactam. It is another object of the present invention to provide a method for producing a zeolite which is more excellent from the viewpoint of catalytic activity. The object of the present invention is to provide a zeolite used as a catalyst by reacting the zeolite obtained in such a manner that the cyclohexanone oxime The reaction is carried out at a high conversion rate, and epslion-caprolactam is obtained at a high selectivity, so that it can be produced with good productivity. The present invention provides a method in which at least one compound selected from the group consisting of a boron compound and a germanium compound, a tetraalkyl orthosilicate, water and a quaternary ammonium hydroxide are mixed to form a hydrothermal synthesis reaction of the resulting mixture, The resulting zeolite crystal is subjected to solid-liquid separation, and the obtained zeolite crystal is fired, and the calcined zeolite crystals are subjected to contact treatment with an aqueous solution containing at least one acid selected from the group consisting of an inorganic acid and an organic acid to produce Zeolite.
