Investigation on the influence of the TBP diluents on the primary emulsion stability in model extraction systems: TBP-diluents-water solutions of HNO3

In the extraction systems containing little quantities of TBP in carbon tetrachloride (CCl4) and kerosene the stable emulsions are created; for higher concentrations of TBP the emulsion stability decreases and increases again for the highest concentrations of TBP. In the TBP solutions in N-octane and benzene the great influence on the primary emulsion stability is observed only for the high concentrations of TBP. The addition of MBP has considerably less influence on the primary emulsion stability than the addition of DBP has, for all used diluents. (author)
