Liquid–Liquid Equilibrium for Ternary System of Water + 2-Methyl-3-buten-2-ol + (Methyl tert-butyl ether/Butyl acetate/4-Methyl-2-pentanone/2-Ethyl-1-hexanol) at 308.2 K

Experimental Determination and Thermodynamic Modeling of Liquid–Liquid Equilibrium for the Ternary Mixture System: Water + 3-Pentanone + Different Solvents at 308.2 K under 101.3 kPa

“…The experimental device of liquid–liquid phase equilibrium is depicted in Figure according to the literature. − In 308.2 K and 101.3 kPa, the liquid–liquid experiment data for water + 3-pentanone + solvents ternary systems were measured. Throughout the experiment, the reagents were weighed by using FA2004 analytical balance with a resolution of ±0.0001 g, and the solvents (methyl tert-butyl ether, 2-ethyl-1-hexanol, o-xylene, ethyl acetate) and water were added in a mass ratio of 1:1 (according to the extraction ratio, also called the solvent to oil ratio) as the initial composition into the 100 mL equilibrium cell.…”

Experimental Study and Thermodynamic Modeling of Ternary Liquid–Liquid Equilibrium of Water + 2,2,2-Trifluoroethanol + Four Solvents at 298.2 K

“…Experimental equipment and detailed methods are also described in previously published papers. − The experiment of water + TFE + {MIBC or MIBK or MIPK or benzyl alcohol} was carried out at 298.2 K. During the entire experimental measurement process, under the condition that precise control of the temperature fluctuation range is less than 0.1 K, the water, the extractant and trifluoroethanol mixture was added to the equilibrium kettle, thoroughly agitated for 4 h, and allowed to equilibrate for 8 h. The organic phase and the lower aqueous layer were sampled for chromatographic analysis.…”
