Abstract
PURPOSE:To produce a composite semipermeable membrane having high desalting capacity and high water permeability by the interfacial polycondensation reaction of a polyfunctional amine with a polyfunctional acid halide wherein 4-chloroformyl phthalic anhydride is contained in the reactants. CONSTITUTION:A fine porous base film such as fiber-reinforced polysulfone base film is dipped in an aq. soln. of polyfunctional aromatic amine having >=2 amino groups in a molecule such as 1,3,5-triaminobenzene, etc. After removing the excess aq. amine soln. by draining the dipped film, a soln. of polyfunctional acid halide such as 1,3,5-benzene tricarboxylic acid chloride and 4-chloroformyl phthalic anhydride and an acylating catalyst such as dimethyl formamide in trichlorotrifluoroethane is applied on the film. Thus, a superthin layer of crosslinked polyamide is formed on the base film by the interfacial polycondensation of a polyfunctional aromatic amine with a polyfunctional acid halide.
