Document Type and Number:
WIPO Patent Application WO/2017/155004
Kind Code:
A1
Abstract:
[Problem] To provide a porous hollow fiber membrane having excellent chemical resistance and mechanical strength, a production method therefor, and a filtration method using the porous hollow fiber membrane. [Solution] A porous hollow fiber membrane (10) in which: the porous hollow fiber membrane (10) includes at least a first solvent and a second solvent; the first solvent is at least one compound selected from a sebacic acid ester, a citric acid ester, an acetyl citric acid ester, an adipic acid ester, a trimellitic acid ester, an oleic acid ester, a palmitic acid ester, a stearic acid ester, a phosphoric acid ester, a C6–30 fatty acid, and an epoxidized vegetable oil; the second solvent differs from the first solvent, and is at least one compound selected from a sebacic acid ester, a citric acid ester, an acetyl citric acid ester, an adipic acid ester, a trimellitic acid ester, an oleic acid ester, a palmitic acid ester, a stearic acid ester, a phosphoric acid ester, a C6–30 fatty acid, and an epoxidized vegetable oil; and the porous hollow fiber membrane (10) has a three-dimensional mesh structure.
