Composite reverse osmosis membrane |
| abstract |
(57) [Summary] [Object] The present invention provides a composite reverse osmosis membrane having a high salt rejection, a high chlorine bactericide resistance and a high stain resistance for the selective separation of components in a liquid mixture. To provide. A composite reverse osmosis membrane comprising a thin film and a microporous support film supporting the thin film, wherein the thin film comprises (a) an essentially monomeric compound having at least two primary or / and secondary amino groups. At least one selected from the group of body amine compounds A species-containing amine component and (b) at least one species selected from the group of essentially monomeric difunctional acid halide compounds having an aliphatic ring or a benzene ring containing at least one fluorine atom in the ring. It is characterized in that the main component is a polyamide comprising an acid halide component containing a bifunctional acid halide component as a main component. |
