Partition Coefficients for Acetic, Propionic, and Butyric Acids in a Crude Oil/Water System

Phase equilibria for ternary liquid systems of (water+carboxylic acid or alcohol+1-hexanol) at T=293.15 K: modelling considerations

“…The efficient separation of organic acids and alcohols from aqueous solutions is an important concept in the chemical fermentation industry where many solvents have been tested to improve such recovery [1,2,6,[3][4][5]. Especially, extractive recovery of acetic acid by selective solvent systems from aqueous solutions, such as fermentation broth and wastewater including lower than 10% (w/w) acid concentrations has received increasing interest [7,8].…”

Liquid–liquid equilibria for the system (water+carboxylic acid+chloroform): Thermodynamic modeling

“…[1][2][3][4][5]. The distribution of C2-C5 carboxylic acids in the (water + chloroform) two-phase system is better for acetic and valeric acids than pyruvic acid.…”

Phase equilibria of ternary systems (water+pyruvic acid+high boiling alcohol). Thermodynamic modeling and optimization of extraction

“…In the chemical industry, various selective solvent systems have been tested to improve the efficient separation of carboxylic acids from aqueous fermentation solutions [1,2]. Especially, extractive recovery of acetic acid by selective solvent systems from aqueous solutions, such as fermentation broth, has received increasing interest [3,4].…”
