The lowest surface tension of N_xB solution was better at 25℃, and lowest surface tension would down with carbon . cmc( critical micelle concentration) and γ_ in N_(12)B are 4.1 × 10~(-4)mol/L, 24.5 mN.m~(-1),what was smaller than LAS . 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.
