摘要

本文报道了小直链和环季铵碘化物溶液以及甲基和乙基碘化吡啶溶液在25°C下的粘度和密度测量。除吡啶盐外，每个CH2基团的表观摩尔体积φ°ν和粘度b系数Bη的变化都是恒定的(分别为0.015 dm3 mol-1和0.067 dm3 mol-1)，关系式为Bη= 4.6 φ°ν - 0.54。

Dilute aqueous solutions of unsymmetrical quaternary ammonium iodides. Part 1.—Viscosity and density measurements

Viscosity and density measurements at 25°C on solutions of small straight-chain and cyclic quaternary ammonium iodides, and on methyl and ethyl pyridinium iodide are reported. The derived apparent molal volumes ϕ°ν and viscosity B-coefficients Bη change by constant amounts (0.015 dm3 mol–1 and 0.067 dm3 mol–1 respectively) per CH2 group for all except the pyridinium salts, and are related by the equation Bη= 4.6 ϕ°ν–0.54.
