Solid–liquid equilibrium in the ternary system acetic acid–propanoic acid–formamide

Phase Equilibrium Study of the Aqueous Solution of Propanoic Acid with Acetates at Different Temperatures

“…Nowadays, the study of liquid–liquid equilibrium and phase behavior of ternary mixtures containing organic acids has increased due to impressive recovery of the acids from dilute solutions. Carboxylic acids are used in the food, pharmaceutical, and chemical industries. , Dilute solutions of carboxylic acids are produced by chemical synthetic or fermentation processes. − In order to separate the carboxylic acid from aqueous solutions, liquid + liquid extraction is used as a popular recovery method . Liquid–liquid equilibrium data are required for liquid extraction of organic acids, and the first step in liquid extraction is the choice of solvent.…”

Volumetric behavior of the ternary system (methyl tert-butyl ether + methylbenzene + butan-1-ol) and its binary sub-system (methyl tert-butyl ether + butan-1-ol) within the temperature range (298.15 to 328.15) K

“…Further, the excess molar volumes are also predicted by the Peng-Robinson equation of state [12][13][14][15]. The results obtained were used to interpret molecular packing, molecular association or molecular interactions existing in the studied liquid systems [12,[16][17][18][19][20][21].…”
