| titleOfInvention | Composite semipermeable membrane and method for producing the same |
| abstract | (57) [Summary] [Problem] To provide a composite semipermeable membrane in which the water permeability of the membrane is improved, and the decrease in organic substance rejection performance due to the improvement in water permeability is small. SOLUTION: In the composite semipermeable membrane comprising a microporous support membrane coated with an ultrathin film layer of a crosslinked polyamide, the crosslinked polyamide has the following features: i) an alkyl group having 3 or more carbon atoms as a substituent on N. N-alkyl amide, N, N-dialkyl amide, ii) cyclic alkyl amide having a cyclic structure having 5 or more carbon atoms, N-alkyl cyclic alkyl amide, iii) substituent of an alkyl group having 1 or more carbon atoms on N N, N, N ', N'-tetraalkyl urea having the formula: iv) a cyclic structure containing an alkylene chain having 3 or more carbon atoms; Interfacial polycondensation in the presence of at least one amide or urea or phosphoramide selected from the group consisting of alkylene urea having 1 or 2 alkyl groups, v) hexaalkyl phosphoramide having an alkyl group having 1 or more carbon atoms as a substituent on N. Composite semipermeable membrane characterized in that it is a crosslinked polyamide. |
