Abstract

The aggregation equilibria of tri-n-dodecylammonium hydrogensulphate (TLAH₂SO₄) and hydrogenchromate (TLAH₂CrO₄) dissolved in toluene have been studied by vapor pressure osmometry at 40°C. The experimental data can be best fit by the formation of the species (TLAH₂SO₄)₄ (log β₄ = 6.3 ± 0.2) and (TLAH₂SO₄)₅ (log β₅ = 8.0 ± 0.2) in the acid sulphate system and (TLAH₂CrO₄)₂ (log β₂ = 0.75 ± 0.07) in the acid chromate one.
