Phase equilibria for liquid mixtures of (benzonitrile + a carboxylic acid+ water) atT= 298.15 K

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].…”

Mass Transfer during Solute Extraction from a Droplet with Internal Circulation in the Presence of a Constant Uniform Electric Field

“…The water-benzonitrile pair exhibits a very high rate of liquid circulation under the influence of the applied electric field. Notably, benzonitrile is a very good solvent for the extraction of the third component from the aqueous phase (e.g., [10]). Since the rate of mass transfer between a droplet and a continuous phase during extraction increases with increasing interfacial fluid velocity (e.g., [3]), an enhancement of the rate of extraction for the water-benzonitrile system, under the influence of the electric field, can be expected.…”

“…The influence of the deacetylation process on the physicochemical characteristics of chitosan from chitin was discussed [9]. Domard et al [10,11] comparatively studied the heterogeneous deacetylation of a-and b-chitins from shrimp shells and squid pens in a multistep process, which allowed them to obtain a high molecular weight and high DD of chitosan [3,10,11]. However, there are no fundamental studies on the kinetics of the b-chitin deacetylation reaction in the literature.…”

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

“…The efficient separation of carboxylic acids from aqueous solutions is an important concept in the chemical fermentation industry where many solvents have been tested to improve such recovery [1][2][3][4][5][6]. 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].…”
