Abstract

The partial molal volumes and relative viscosities of tetraethylammonium chloride in a series of dimethyl sulfoxide (DMSO)-water mixtures were measured at $30^{\circ}C$. A maximum structuredness of solvent, that leads to a minimum viscosity A-coefficient and a maximum viscosity B-coefficient of the Jones-Dole equation(${\eta}_r=1+AC^{1/2}$ + BC), was found at 0.2${\sim}$0.3 mole fraction of DMSO. The solvent structure, that leads to a minimum partial molal volume due to the maximum electrostrictive effect of chloride ion and to a minimum viscosity B-coefficient, was found at 0.4${\sim}$0.5 mole fraction of DMSO. An approximate relationship between the limiting effective flowing volume, $V_e^{\circ}$, and the B-coefficient was found to be B = 2.5 $V_e^{\circ}$ in the Einstein equation.

여러 組成의 dimethyl sulfoxide(DMSO)-물 混合溶媒中에 tetraethylammonium chloride$((C_2H_5)_4NCl)$의 分몰容積 및 相對粘度를 $30^{\circ}C$에서 測定하였다. 그 結果로 부터 DMSO의 몰分率이 0.2${\sim}$0.3인 組成에서 溶媒構造가 가장 强化된 상태임을 알았으며 이것은 粘度에 關한 Jones-ole式(${\eta}_r=1+AC^{1/2}$+BC)의 A-係數의 最小値 및 B-係數의 最大値의 現象을 나타낸다. 또한 DMSO의 몰分率 이 0.4${\sim}$0.5인 組成에서는 溶媒構造가 가장 파괴된 상태로서 $Cl^-$의 强한 electrostriction 效果로 因한 收縮으로 分몰容積이 最小値이며, 粘度 B-係數가 最小로 나타남을 알았다. 그리고 limiting effective flowing volume $V_e^{\circ}$와 粘度 B-係數와의 사이에 B=2.5$V_e^{\circ}$의 관分率계가 近似的으로 成立함을 確認하였다.
