Abstract
PURPOSE: To maintain a selective permeability of a membrane under a long period of an electrolytic condition and maintain an electric resistance at a low value, by treating a cation exchange membrane contg. SO3 radicals as ion exchange radicals with primary to tertiary monoamine salt or quaternary ammonium salt, and then treating it with heat within a specified temp. range to dry it.
CONSTITUTION: The above-mentioned cation exchange membrane (e.g. fluorine contg. sulphonic acid type cation exchange membrane) is treated with an aq. soln. of primary to tertiary monoamine salt or quaternary ammonium salt of the formula (e.g. trimethylamine hydrochloride) with a concn. of 1W5mol/l. The membrane treated with amine salt is then treated with heat at a temp. below the m.p. of the reactant and higher than 100°C, pref. at 140W230°C, more pref. at 150W200°C. The ion exchange membrane obtd. after treated with amine and heat is useful for electrolysis of alkali halide and it shows high cation selectivity.
