Liquid–liquid equilibrium for the ternary systems of water+acetyl acetone+propyl acetate at several temperatures

(Liquid+liquid) equilibria for the ternary (water+acetic acid+toluene) system at different temperatures: Experimental data and correlation

“…The highest separation (about 100) is achieved when its aqueous phase mass fraction is about 0.27. A similar variation can be deduced from the data presented by Dakshinamurty et al [9] or from the literature [14,15]. These results indicate that a high separation can be achieved when there is an acetic acid aqueous phase mass fraction of about 0.27 at the lower temperatures.…”

Experimental Liquid–Liquid Equilibrium and Solubility Study of an Acetic Acid–n-Propyl Alcohol–n-Propyl Acetate–Water System at 323.15 and 333.15 K

“…Comparison of experimental LLE with literature results for the binary subsystem n -propyl acetate–water at 323.15 and 333.15 K (mole fractions, atmospheric pressure): ■this work, ● −, Δ −, ◀ −, ○ −, ▲ − …”

“…Other similar quaternary systems that we previously studied have a similar form of the binodal surface: formic acid−ethyl alcohol−ethyl formate−water, 36 acetic acid−ethyl alcohol−ethyl acetate−water, 31 propionic acid−ethyl alcohol−ethyl propionate−water, 34 and propionic acid−n-propyl alcohol−n-propyl propionate−water. 37 To compare experimental LLE results for the binary system n-propyl acetate−water with the literature data, 11,14,17,38,39 a diagram of the concentration of propyl acetate on temperature was plotted (Figure 7).…”

“…also published several relatively modern works. There are some results on LLE and solubility data for 288.15, 298.15, and 313.15 K at atmospheric pressure. Compositions of coexisting phases in the binary subsystem are also given in ref at 288.2, 303.2 K for the pressure near atmospheric (95 kPa).…”
