摘要：
Solubility and tie-line data for the (water + formic acid + 1-decanol) ternary system were determined at T=298.2, 303.2, 313.2, and 323.2 K and atmospheric pressure. Solubility data were obtained by cloud-point titration method. Distribution coefficients and separation factors were measured to evaluate the extracting capacity of the solvent. The consistency of the experimental tie-line data was determined through the Othmer-Tobias and Bachman equations. The NRTL model was used to correlate the experimental data. The influence of temperature on the equilibrium characteristics and separation factor was found to be small at the temperatures studied. The average root-mean-square deviation between the experimental and calculated mass fractions was 0.66%. The thermodynamic model showed a good regression fit to the experimental results.
