Document Type and Number:
Japanese Patent JP2023061901
Kind Code:
A
Abstract:
To improve catalyst activity, and improve the quality of a polymer.SOLUTION: A method for producing ion-exchanging layered silicate particles includes the following steps 1, 2 and 3. Step 1: a step of preparing a slurry containing a compound [I] containing an ion-exchanging layered silicate, a solvent and aluminum ions, in which in 100 mass% of a solid component contained in the slurry, the compound [I] is 8-80 mass%, and the compound [I] may be one or more kinds, step 2: a step of granulating the slurry prepared in the step 1 by spray and drying, and obtaining ion-exchanging layered silicate composite particles, and a step 3: a step of eluting at least a part of a metal component contained in the ion-exchanging layered silicate composite particles obtained in the step 2.SELECTED DRAWING: None
