Critical Micelle Concentration (CMC) of sodium dodecyl sulfate (SDS), an anionic surfactant, has been investigated in 30 mM aqueous solutions of 1-benzyl-3-methylimidazolium chloride (1) and 1-methyl-3-(pentafluorophenyl)imidazolium chloride (2). The CMC of SDS is significantly lower in the presence of 2 as compared to that of 1. The decreased CMC of SDS in the presence of 2 is in accordance with its increased hydrophobicity due to the fluorinated side chain. The thermogravimetric analysis of compounds 1 and 2 shows that they are thermally stable up to about 290 degrees C.
已在1-苄基-3-甲基咪唑鎓氯化物（1）和1-甲基-3-（五氟苯基）咪唑鎓氯化物（2）的30 mM水溶液中研究了阴离子表面活性剂十二烷基硫酸钠（SDS）的临界胶束浓度（CMC）。与1相比，在2存在下SDS的CMC显著更低。在2存在下SDS的CMC降低与其因氟化侧链导致的疏水性增加一致。化合物1和2的热重分析表明它们在高达约290℃时热稳定。
