(Liquid+liquid) equilibria of (water+propionic acid+dimethyl phthalate) at several temperatures

Phase equilibria of water+1-propanol+solvent (n-amyl acetate, cyclohexanol, and cyclohexyl acetate) at T=298.2K

“…The LLE apparatus and experimental procedure were previously described in detail [14,15]. Tie-line data determination was performed in an equilibrium cell equipped with a magnetic stirrer and isothermal fluid jacketed beaker to keep the temperature of the stock solution constant.…”

(Liquid+liquid) equilibria of (water+propionic acid+diethyl succinate or diethyl glutarate or diethyl adipate) ternary systems

“…Many solvents have been tried and tested to improve the recovery of propionic acid from aqueous solutions, and phase equilibrium data of the related systems are reported in the literature [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

(Liquid+liquid) equilibria of (water+propionic acid+dipropyl ether or diisopropyl ether) at T=298.2K

“…The LLE apparatus and experimental procedure were previously described in detailed [10,11]. Tie-line data determination was performed in an equilibrium cell equipped with a magnetic stirrer and isothermal fluid jacketed beaker to keep the temperature of the stock solution constant.…”

“…Recovery of the organic acid from aqueous solutions that are resulted from fermentation processes is also of considerable economic importance. Many solvents have been used to enhance the extraction of propionic acid from aqueous solutions [1][2][3][4][5][6][7][8][9][10][11].…”
