Document Type and Number:
Japanese Patent JP6791945
Kind Code:
B2
Abstract:
[Problem to be solved] A porous hollow fiber membrane having excellent chemical resistance and mechanical strength, a method for producing the porous hollow fiber membrane, and a filtration method using the porous hollow fiber membrane are provided. [Solution] A porous hollow fiber membrane (10) includes at least a first solvent and a second solvent. The first solvent is at least one selected from sebacic acid esters, citric acid esters, acetyl citric acid esters, adipic acid esters, trimellitic acid esters, oleic acid esters, palmitic acid esters, stearic acid esters, phosphoric acid esters, C6-C30 fatty acids, and epoxidized vegetable oils. The second solvent is different from the first solvent, and is at least one selected from sebacic acid esters, citric acid esters, acetyl citric acid esters, adipic acid esters, trimellitic acid esters, oleic acid esters, palmitic acid esters, stearic acid esters, phosphoric acid esters, C6-C30 fatty acids, and epoxidized vegetable oils. The porous hollow fiber membrane (10) has a three-dimensional network structure.
