Abstract:
An object of the present invention is to provide a separation membrane having high permeability and selective removability of divalent/monovalent ions. The separation membrane of the present invention includes a supporting membrane and a separation functional layer formed on the supporting membrane, in which the separation functional layer contains a polymerized product of a polyfunctional amine with a polyfunctional acid halide, the polyfunctional amine contains a polyfunctional aliphatic amine as a main component, the separation functional layer has a hollow protuberant structure, and the separation functional layer has a relative surface area of 1.1-10.0.

Claim (Index 15):
The process for producing a separation membrane according to  claim 14 , wherein the polyfunctional aliphatic amine is a piperazine compound represented by the following general formula (1): (wherein R 1  represents an alkyl group having 1-6 carbon atoms, a phenyl group, a benzyl group, COOR 3 , CONHR 3 , CON(R 3 ) 2 , or OR 3 , where R 3  represents a hydrogen atom, an alkyl group having 1-6 carbon atoms, a phenyl group, or a benzyl group, and R 2  represents a hydrogen atom, an alkyl group having 1-6 carbon atoms, a phenyl group, a benzyl group, COOR 4 , CONHR 4 , CON(R 4 ) 2 , or OR 4 , where R 4  represents a hydrogen atom, an alkyl group having 1-6 carbon atoms, a phenyl group, or a benzyl group).
