✦ Synopsis

FT-IR. Two types of quaternary ammonium bromides (i.e., [4r4r4r4] and ooctanoic acid; ion-pair association; phase separation pheno-[1r1r1r13]) were used as received from Tokyo Kasei Company and Wako menon.

Pure Chemical Company, respectively. Quaternary ammonium bromide aqueous solution 1 mol dm 03 was prepared by dilution with distilled water.

Other materials. Perfluorooctanoic acid (HPFOA) was used as received from Daikin Fine Chemical Lab. Company. A 0.1 mol dm 03 PFOA lithium
