Partial least-squares regression using PLS2 algorithm occurs to provide an effective solution to decomposing complicated spectra, coping with components interferences, nonlinearities and collinearity. The calibration method for the chosen compounds was validated using test samples of known composition and by measuring liquid-liquid equilibria at 298.15 K in the ternary system 1-butyl-3-methylimidazolium hexafluorophosphate + 1-methylimidazole + 1-chlorobutane.
