Title:
IN-LIQUID SUBSTANCE SEPARATION MEMBRANE USING OCTOSILICATE MATERIAL AND PRODUCTION METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2022/239843
Kind Code:
A1
Abstract:
[Problem] To provide: an in-liquid substance separation membrane molded body that is made of highly chemical-resistant components, has a high membrane solvent permeation speed, and efficiently separates the substances (e.g., the ionic organic substances) in a liquid; and a production method for the in-liquid substance separation membrane molded body. [Solution] According to the present invention, an in-liquid substance separation membrane molded body includes: lamellar particles (A) that include a quaternary ammonium ion (a) that has a total of 15–45 carbon atoms and has one or two alkyl groups that have 10–20 carbon atoms and an anion surfactant (b) that has an ammonium ion, have an average thickness of 0.7–100 nm, an average length of 50–10,000 nm, and a (maximum length/width orthogonal to maximum length) ratio of 1.0–10.0, and are a separated layer substance formed by separating the layers of a layered compound; and a base material (B). The lamellar particles (A) are an aqueous dispersion of the lamellar particles (A) that includes (a) and (b) for the separation of the layers of the layered compound. The 90% cumulative particle size value for a laser diffraction particle size distribution of the lamellar particles (A) of the aqueous dispersion is 1.5–10 times the average value for the particle size distribution.
