查询词典 borate

The cmc of N_(12)B- NaCl are down with NaCl up.The surface tension and cmc of N_(12)B and N_(16)B are higher than that of N_(12)OB and N_(16)OB because of hydrophilic group ,but that of N_(12)B is lower than that of N_(16)B because of hydrophobic group .5.

4、25℃，N_xB系列都有较低的表面张力，并随碳原子数的增加而最低表面张力下降。N_(12)B比同碳原子数的十二烷基苯磺酸钠的最低表面张力34.5mN／m低，且临界胶束浓度为4.1×10~(-5)mol／L，也比LAS低，且随着NaCl浓度的增加而略有下降，比较N_(12)B和N_(16)B，由于C_(16)疏水基的异构体使N_(12)B的临界胶束浓度和临界胶束浓度时的表面张力γ_(cmc都低，由于增加了亲水基团使得N_(12)OB和N_(16)OB的表面张力和临界胶束浓度都要高于N_(12)B和N_(16)B。
