摘要
C 12-6-C 12·2Br violently interacts with sodium dodecyl sulfate(SDS) leading to the formation of mixed micelles. When molar fraction(x 2) of C 12-6-C 12·2Br in the bulk solution was 10.0%, the total critical micelle concentration(cmc T) of the mixed solution was found to be 0.043 7 mmol/L, and the micelle aggregation number N T and the molar fraction(xM 2) of C 12-6-C 12·2Br in the mixed micelle were 17.4 and 49.0%, respectively. With x 2 increased to 16.7%, cmc T further decreased and N T gradually increased, but xM 2 almost remained unchanged. The average value of the interaction parameter(β M) calculated by the theory of regular solution equals to -33.3.
