Liquid–liquid equilibria in the ternary systems water+cresols+methyl butyl ketone at 298.2 and 313.2K: Experimental data and correlation

Measurement, correlation and COSMO-SAC prediction of liquid-liquid equilibrium for the ternary systems, mesityl oxide + o-, m-, p-cresol + water, at 333.2K and 353.2 K

“…The key problem to design a liquid-liquid extraction process is to develop an appropriate extractant with low water solubility, low price and high efficiency to separate cresols from water. However, such study or data is quite scarce at present, with just a few solvents (or extractants) having been reported [20][21][22][23][24]: at 298.2 K, the distribution coefficient (D) and selectivity (S) of methyl tert-butyl ether for cresols are 800~1200 and 3500~13700, those of methyl isopropyl ketone are 390~1450 and 1300~7800 and those of methyl propyl ketone are 530~1450 and 1900~8900. As a polar organic solvent, Mesityl oxide have shown high efficiency in extracting phenol from the aqueous solution [26].…”

Liquid-liquid equilibria for methyl isobutyl ketone + cresols + water at 333.15 K, 343.15 K and 353.15 K: Experimental results and data correlation

“…The oven initial temperature was held at 313. 15 The composition of the sample was determined by an internal standard method, where n-butyl acetate was used as an internal standard for MIBK and 1, 3, 5-trimethylbenzene for cresols. The water' mole fraction was calculated from deducting those of the other two component (MIBK and cresols) from 1.…”

“…Kupatkin et al [14] studied the ternary systems, (trimethylcarbinol + o-cresol + water) and (trimethylcarbinol + m-cresol + water) at 298.2 and 323.2K. The system (methyl butyl ketone + o-, m-, p-cresol + water) at 298.2 and 313.2K was investigated by Lv et al [15]. The LLE data of the systems, (2-methoxy-2-methylpropane + o-, m-, p-cresol + water) at 298.15 and 313.15 K were reported by Luo et al [16][17][18].…”

Measurement and thermodynamic modeling of ternary (liquid + liquid) equilibrium for extraction of o-cresol, m-cresol or p-cresol from aqueous solution with 2-pentanone

“…However, only a few studies have been reported for the LLE data in cresols extraction from aqueous solution till now [12][13][14][15][16], searching for a new and more suitable solvent for the removal of cresols is still the primary consideration. 2-Pentanone, as a polar solvent, has already been investigated as an extraction solvent of aliphatic acids including acetic acid and propanoic acid, and showed excellent extraction efficiency in extracting above organic acids [17][18][19].…”
