Electric conductivity of liquid ion exchangers

Abstract

Electric conductivities of chloroform solutions of di-(2-ethylhexyl) hydrogen phosphate and bisulphates and hydrochlorides of two secondary long-chain amines Amberlite LA1 and LA2 were measured. All these liquid ion exchangers appear to be dissociated in chloroform and behave like weak electrolytes. No micelle aggregation occurs in the organic phase. This was confirmed by refractive index measurements. Minima visible on some conductivity curves indicate formation of ionic pairs and triplets. Amine bisulphates are stronger electrolytes than amine hydrochlorides.
