Liquid+liquid equilibria for the quaternary systems of (water+acetic acid+mixed solvent) at 298.2K and atmospheric pressure

Correlation of Experimental Liquid–Liquid Equilibrium Data for Ternary Systems Using NRTL and GMDH-Type Neural Network

“…Because of the lower energy requirement and costs, liquid–liquid extraction is considered as rather an effective and suitable method for carboxcylic acid recovery. For an efficient recycling of these compounds, many different solvents have been used so far by different researchers. − Ternary liquid–liquid equilibrium (LLE) data of carboxylic acids for aqueous solutions with organic solvents are of great importance in terms of both academic research and industrial applications. LLE data constitute a critical point in the design and improvement of various separation operations or chemical processes.…”

Liquid–liquid equilibrium of water+acetic acid+butyl butanoate at 298K and 1 atmosphere

“…The reliability of experimental and predicted tie-line data can be ascertained by Othmer-Tobias regression [9][10][11][12][13][14] equation which is given as,…”

“…The separation of acetic acid from its aqueous form is a challenging industrial problem [1][2][3] and many studies have been reported for the recovery of the acetic acid with different solvents [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. When acetic acid is to be recovered at very high concentration the solvent used has to exhibit almost negligible solubility for water besides satisfying the desired specific characteristics such as high distribution coefficient, high separation factor, good selectivity towards the given solute, and the general characteristics such as boiling point difference between the solvent and extractant, viscosity, density, interfacial tension, corrosiveness, flammability, toxicity, compatibility, availability, and cost [2,[4][5][6].…”
