Electrolyzers, membrane comparison

The properties of the membrane hydrolyzed with 10 % sodium hyroxide were measured, and a saturated sodium chloride solution was electrolyzed using this membrane. The results are given in Table I. For comparison, the sulfonyl chloride-type membrane was treated in n-butyl alcohol at 110 °C for 3 hours without introducing air. The treated membrane was subjected to hydrolysis treatment in a methanol solution containing 10 % of sodium hydroxide. Electric resistance of the membrane was 450 —cm, and the current efficiency could not be measured.
