碳氟醇对十烷基硫酸钠水溶液的表面活性及反离子结合度的影响

The Effect of 2.2.3.3.4.4.4 Heptafluorobutanol onSurface Activity and Counterion Binding Degreeof C_(10)H_(21)SO_4Na Aqueous Solution

通过用滴体积法测定溶液的表面张力,用电导法测定溶液的电导串来研究C_3F_7CH_2OH与C_(10)H_(21)SO_4Na混合水溶液的物理化学性质。结果表明:C_3F_7CH_2OH或NaCl的加入都能增加C_(10)H_(21)SO_4Na溶液的表面活性,两种方法测得的胶团反离子结合度规律一致,即随着C_3F_7CH_2OH量增加而增加,与C_6H_(13)OH情况不同。

The surface activities and counterion binding degrees of C3F7CH2OH and C10H21SO4Na mixed aqueous solution are measured by surface tension and conductance methods. The results show that when adding C3F7CH2OH into the C10H21SO4Na solution the surface activity of C10H21SO4Na and the counterion binding degree of micelle are increased.
