摘要：

The aggregation equilibria of tri-n-dodecylammonium hydrogensulphate (TLAH2SO4) and hydrogenchromate (TLAH2CrO4) dissolved in toluene have been studied by vapor pressure osmometry at 40-degrees-C. The experimental data can be best fit by the formation of the species (TLAH2SO4)4 (log beta4 = 6.3 +/- 0.2) and (TLAH2SO4)s (log beta5 = 8.0 +/- 0.2) in the acid sulphate system and (TLAH2CrO4)2 (log beta2 = 0.75 +/- 0.07) in the acid chromate one.
