Liquid-Liquid Extraction Data- Partial Pressures of Ternary Liquid Systems and the Prediction of Tie Lines

Abstract

value of the reciprocal is read immediately, to give in this case 2.13 at point 1. Unity is subtracted, to obtain 1.13 at point 2, which thus has the value of (1/5) -1. In a similar manner, a value for (1/ ) -1 is obtained from the value of a = 0.65¡ taken on the horizontal axis, projected to the y = l/x line to give 1.54 at point 5, from which unity is subtracted to give 0. 54 at point 4. From point 4 and point 2 is obtained point 3, one value on the tie line curve. Other points are plotted similarly.

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

“…The experimental tie-line data at each temperature were correlated to test consistency by the Othmer and Tobias [12] correlation (Eq. (1)) and Bachman [13] correlation (Eq.…”

Liquid–Liquid Equilibrium Measurements for the Ternary System of Water/2,3-Butanediol/4-Methyl-2-pentanol at Various Temperatures

“…In this work, to provide a database for the potential liquid–liquid extraction process using 4-methyl-2-pentanol as a solvent, isobaric LLE data of the water/2,3-BDO/4-methyl-2-pentanol system have been measured at temperatures from 298.2 to 318.2 K. LLE data for this ternary system are not available in the literature. To verify the LLE data, Othmer–Tobias and Hand plots were used. Also, for each temperature, both the separation factors and the distribution coefficients were evaluated using the LLE data.…”

Measurement and Correlation of Liquid-Liquid Equilibria for Ternary Systems of Water + rubidium Chloride + propanol

“…The reliability of the measured tie line compositions was ascertained using the correlation equations provided by Othmer and Tobias (1942) for Equation (2) and Bancroft (1897) for Equation (3): Figure 2.
