Title:
METAL-ORGANIC FRAMEWORK DISPERSION PRODUCTION METHOD, METAL-ORGANIC FRAMEWORK DISPERSION, AND METAL-ORGANIC FRAMEWORK COMPOSITION INCLUDING METAL-ORGANIC FRAMEWORK DISPERSION
Document Type and Number:
WIPO Patent Application WO/2024/048308
Kind Code:
A1
Abstract:
[Problem] To provide a method for using a mechanical pulverization technique to produce a dispersion comprising a nm-size metal-organic framework which has good dispersion stability while maintaining a crystal structure. [Solution] A metal-organic framework dispersion production method comprising: a step (1) for mixing a component (a), which is a solid powder of a metal-organic framework that contains metal ions and organic ligands coordinated to the metal ions, said metal ions being at least one type selected from the group consisting of Zr ions, Al ions, and Zn ions, a component (b), which is a dispersant and which is an aliphatic amine compound that is a primary amine, a secondary amine, or a tertiary amine having one amino group in a molecule thereof, and which is soluble in a dispersion medium (c1), and a component (c1), which is said dispersion medium; and a step (2) for using the obtained mixture to produce a dispersion via a mechanical pulverization technique (wherein in the mechanical pulverization technique, the crystal structure of the metal-organic framework (a) does not change, and the crystal structure of the solid powder is maintained).
