Deep eutectic solvents (DESs) are ionic liquid analogues that consist of Lewis or Brønsted acids and bases. These systems characterized by a substantial decrease in melting points as compared to those the neat constituents. Activity coefficients at infinite dilution organic solutes is used screening tool for extracting solvents, an approach useful identifying acceptable precursors assessing separation performance practical applications. This review assesses effectiveness DESs chemical...
Gas liquid chromatography was used to determine solute retention data for 33 volatile organic solvents: alkenes, alkanes, alkynes ketones, alcohols, aromatic hydrocarbons, tetrahydrofuran, acetonitrile, thiophene, and water in the new ionic (IL) 2,3-dihydroxypropyl-N-methyl-2-oxopyrrolidinium chloride [(OH)2C3MPyr][Cl]. This work conducted order evaluate IL use separation processes, evaluation based on experimental activity coefficients at infinite dilution. γ13∞ obtained four different...
The study examined the interactions between a deep eutectic solvent (DES) containing choline chloride (ChCl) along with ethylene glycol (EG) in molar ratio of 1:3, and three carboxylic acids: acetic acid, propanoic acid butanoic acid. structural stability, electrical characteristics dynamic behavior these DES-carboxylic systems were investigated utilizing techniques like density functional theory (DFT), natural bond orbital (NBO) analysis molecular dynamics (MD) simulations. results showed...
The separation of volatile organic solvents (herewith, solutes) were tested in an imidazolium-based ionic liquid (1,3-dimethylimidazolium dimethylphosphate), [MMIM] [DMP] as a solvent at four different temperatures, T = (313 .15 to 343.15) K and atmospheric pressure. solutes include alcohols, aromatic hydrocarbons, thiophene, ketones, alkanes, alkynes, alkenes, acetonitrile, THF, well water. potential the investigated was based on activity coefficients infinite dilution, γ13∞, solutes. This...
In this work densities, speeds of sound, and refractive indices the binary mixtures involving 2-amino-2-methyl-1-propanol (AMP) with acetonitrile, toluene, 1-pentanol, 1-hexanol were measured at different temperatures, T = (303.15, 313.15 323.15) K over whole composition range (xAMP 0–1) atmospheric pressure. The derived properties including excess molar volumes, VmE, isentropic compressibilities, κs, deviation in Δκs, indices, ΔnD calculated from experimental correlated as a function...
Abstract Zinc (II) chloride based deep eutectic solvent (DES) were formed by mixing zinc with phosphoric acid. Fourier‐transform infrared spectroscopy was used to identify any possible shifts when the two compounds assorted, and differential scanning calorimetry (SDT Q600 V20.9 Build 2D) utilized evaluate formation of solvent. Densities, , speed sound, u [ZnCl 2 ][phosphoric acid] 1:2.5 methanol, ethanol, or propanol have been measured at T = (293.15, 303.15, 308.15, 313.15) K atmospheric...
Abstract This manuscript represents the physical quantities comprising densities, speed of sound and refractive indices for binary mixtures involving [2‐Benzylaminoethanol (BAE) with methanol, ethanol, 1‐propanol, or 2‐propanol] over a molar composition ( x BAE =0–1). The measurements were conducted use Anton Paar densimeter (DSA 5000 M) operated at different temperatures, T=(293.15–323.15) K atmospheric pressure. intermolecular interactions occurring between prepared interpreted by...
Activity coefficients at infinite dilution (γ13∞) for organic solutes in deep eutectic solvent (DES) prepared by {1-butyl-2,3-dimethylimidazolium chloride (BDMIM Cl) + ethylene glycol (EG)} a molar ratio of 1:3 have been measured using the gas–liquid chromatographic method (GLC). The thermal stability entrainer was determined thermogravimetric analyzer. measurements were carried out temperature range T = (313.15 to 343.15) K and atmospheric pressure. values partial excess enthalpies (H1E,∞)...
