چکیده

New experimental data on liquid-liquid equilibria (LLE), solubility and critical states in quaternary system propionic acid – 1-propanol n-propyl propionate water at 303.15 K atmospheric pressure are presented. LLE was studied by Gas Chromatography (GC). Solubility (plait) points were investigated “cloud-point technique” method. Binodal curves surfaces presented concentration tetrahedron. The curve is 3d space. A comparative analysis of the results obtained work with literature carried out. correlated NRTL model. Standart deviation σ for mixture does not exceed 0.344%.

Phase Equilibria of the Ternary System Water + Phosphoric Acid + 1-Nonanol at Different Temperatures

The purpose of this reaserch is to measure the phase equilibrium data of the ternary system (water + phosphoric acid + 1-nonanol) at different temperatures. Experimental solubility curves and tie-line points for the system were obtained at T = 298.2, 308.2 and 318.2 K and ambient pressure. The binodal curve data were detected by the cloud point method. The mass fractions of each layer ...

Liquid-liquid Equilibria of the Water- Acetic Acid-butyl Acetate System

Experimental liquid-liquid equilibria of the water-acetic acid-butyl acetate system were studied at temperatures of 298.15±0.20, 303.15±0.20 and 308.15±0.20 K. Complete phase diagrams were obtained by determining solubility and tie-line data. The reliability of the experimental tie-line data was ascertained by using the Othmer and Tobias correlation. The UNIFAC group contribution method was use...
