説明
Determination was made of critical micelle concentrations (cmc) for four homologs of perfluoroalkanoate salts, CnF2n+1COOLi (n=510), CnF2n+1COONa (n=58), CnF2n+1 COOMe4N (n=510), and CnF2n+1COOEt4N (n=410), in aqueous solution at 25°C. The results were expressed as, log cmc=A+Bn. B values were -0.445-0.463, indicating cmc to decrease by 2.82.9 for each CF2 group added to the perfluoroalkyl chain. The effects of counter ions on cmc for C7F15COO-M+ (M=Li, Na, K) were examined at 35°C. It was found that cmc decreased in the order of Li>Na>K. Limiting partial molar volumes (V0) for CnF2n+1COOMe4N (n=16) in water were measured at 25°C.V0 values increased with the number of carbon atoms ; the increment per CF2 group was 23.7 cm3·mol-1 on the average.
