Abstract: The LLE data of eight ternary systems (n-butanol-water and butanone-water with NaCl, KCl, KBr) were determined experimentally. A saturation-density method was proposed to determine the concentration of mixed solvents containing salt. The Chen model was used to correlate the LLE data satisfactorily.

Key words: Salting effect, n-butanol-water-salt system, Butanone-water-salt system, LLE date, Chem model
