摘要： 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.

摘要： This invention relates to a composite semipermeable membrane of low-pressure high desalination type having an excellent chlorine resistance and a method for the production thereof. This membrane is composed of a microporous supporting membrane and an ultrathin membrane covering said supporting membrane, wherein the ultrathin membrane comprises a polyamide prepared by the polycondensation of a dicarboxylic acid halide with piperazine and ethylenediamine as the main component and a molar fraction of ethylenediamine polyamide constituents to piperazine polyamide constituents is regulated to be in the range of 0.01 to 0.25, so that the membrane has a high desalination rate, a high fresh water generation rate and a sufficient chlorine durability. Thus it can be used in a small ultrapure water generator and a household water purifier and as a reverse osmosis membrane for treating waste water or the like.
