| titleOfInvention | Process for producing composite semipermeable membrane |
| abstract | A process for producing a composite semipermeable membrane, which comprises coating a microporous support membrane with a polyamide formed by the interfacial polycondensation between a polyfunctional aromatic amine and a polyfunctional acyl halide. The polyfunctional aromatic amine component contains, as the comonomer component, 1 to 20 wt %, based on said aromatic amine, of at least one member selected from among alkyldiamine, 1,3,5-trihydroxybenzene and 1,3-dihydroxybenzene, and hence the resulting composite semipermeable membrane has markedly improved oxidation resistance while maintaining the excellent highly selective separative function and high permeability of a crosslinked polyamide type composite semipermeable membrane. This membrane can be suitably used for desalting of brine or seawater. |
