摘要：
The apparent molar volumes, Vφ of tetramethylammonium, tetraethylammonium, tetrabutylammonium, butyltriethylammonium, dibutyldiethylammonium, and tributylethylammonium bromides have been measured at 298.15K in the concentration range from 0.01 to 0.04mol⋅kg−1. The concentration dependence of Vφ is given using the Redlich and Meyer relation. The apparent molar volume at infinite dilution, V∘_φ, and the empirical constant, BV, have been calculated. The CH2-group contribution has been obtained by the additivity rule. The results were interpreted in terms of solute–solvent interactions.
