Abstract

The aggregation equilibria of tri-n-dodecylammonium hydrogensulphate (TLAH 2 SO 4 ) and hydrogenchromate (TLAH 2 CrO 4 ) 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 (TLAH 2 SO 4 ) 4 (log β 4 = 6.3 ± 0.2) and (TLAH 2 SO 4 ) 5 (log β 5 = 8.0 ± 0.2) in the acid sulphate system and (TLAH 2 CrO 4 ) 2 (log β 2 = 0.75 ± 0.07) in the acid chromate one.
