用沸点升高法测定了卤化四丁铵在有机溶剂中的平均聚集度。发现溴化四丁铵在苯中的聚集度远大于在氯仿中的。说明溶剂的极性起着首要作用。在氯仿中聚集度的大小顺序为碘化四丁铵>溴化四丁铵>氰化四丁铵。 还测定了溴化与碘化四丁铵混合溶液的聚集度。测得值显著大于它们单独存在时的值。认为存在离子对的渔合聚集体。
The average degree of aggregation of tetrabutylammonium halide in organic solvents was determined by the boiling point increase method. Found that the concentration of tetrabutylammonium bromide in benzene is far greater than in chloroform. Polarity of the solvent plays a primary role. The order of aggregation degree in chloroform is tetrabutylammonium iodide> tetrabutylammonium bromide> tetrabutylammonium cyanide. The degree of aggregation of the mixed solution of brominated and tetrabutylammonium iodide was also determined. Measured values were significantly greater than when they were alone. It is believed that there is a coalescence of ion pairs.
