“…However, from the Table it is found that CPME has smaller enthalpy of vaporization than all the other solvents. It means that CPME would have the greatest energy-saving potential . The solvent, p -xylene, has a larger separation factor, however, it can form azeotropes with both furfural and acetic acid, respectively .…”

Ternary liquid−liquid equilibria (LLE) data for water + furfural + cyclopentyl methyl ether (CPME) and quaternary LLE data for water + furfural + acetic acid + CPME were measured at T = 293.15, 303.15, and 313.15 K and atmosphere pressure (p ≈ 100.25 kPa).In addition, the LLE for the quinary system of {water + furfural + acetic acid + CPME + CaCl 2 } were determined at 303.15 K and atmosphere pressure to study salting effect on the quaternary system. Finally, based on researches of predecessors and our previous work, comparative study of various solvents including CPME, 2-methyltetrahydrofuran (2-MTHF), p-xylene, toluene, methyl iso-butyl carbinol (MIBC), tert-amyl methyl ether (TAME), and methyl tert-butyl ether(MTBE) was demonstrated.

“…On the other hand, interfacial tension (IFT) determinations can be used to describe the kinetics of formation and ignition of fuel drop, which is key information to design fuel atomizers’ size. The available experimental data for CPME are reduced and limited to pure fluid atmospheric properties such as vapor pressures, liquid densities, − interfacial tension, , liquid dynamic viscosity, and refractive index . For the case of CPME based mixtures, there is not available experimental information or theoretical predictions.…”

This work describes the vapor–liquid equilibrium (VLE) data experimentally measured at three isobaric conditions 50, 75, and 94 kPa and over the temperature range from 334 to 375 K and the atmospheric interfacial tensions (IFT) measured at the isothermal of 298.15 K in the whole mole fraction range for the ethanol + cyclopentyl methyl ether binary system. In order to carry out the experimental determinations, a dynamic all-glass Guillespie type cell was used to carry out VLE measurements, whereas a maximum differential bubble pressure tensiometer was used to IFT determinations. Because few experimental data are available for cyclopentyl methyl ether, vapor pressures and interfacial tensions have also been measured over the temperature range 341–378 K and 298–353 K, respectively. According to the experimental results, the binary system ethanol + cyclopentyl methyl ether displays a positive deviation from the Raoult’s law with a minimum temperature azeotropic over the whole explored pressure range. The azeotropic mole fraction increases in ethanol as pressure and/or temperature increases. For the case of interfacial tensions, they display positive deviation from the linear behavior. The measured VLE data of the ethanol + cyclopentyl methyl ether mixture are thermodynamically consistent as stated by the Fredenlund’s test. Additionally, the VLE were well-correlated by classical activity coefficients models (e.g., Wohl, NRTL, Wilson, and UNIQUAC) for all of the measured isobar conditions. The measured interfacial tensions of the mixture were satisfactorily correlated by the Myers–Scott equation.

In current investigation, cyclopentyl methyl ether (CMPE) was tested as a novel membrane solvent for acetic acid removal from an aqueous medium in the facilitated bulk liquid membrane (BLM). Tributyl phosphate (TBP) has been utilized as a carrier in CMPE to facilitate acetic acid transport. The influences of various operating factors like carrier concentration in the membrane solvent, receiving phase type, and receiving phase concentration on removal, were analyzed. The uptake was evaluated by means of feed (extraction) and receiving yields. Following this, a mass transfer modelling was established and the mass transfer coefficients were determined. The maximum yields were recorded as 95.4% for extraction and 78.01% for receiving yields at 2 mol · L−1 carrier concentration in membrane solvent, and 4 mol · L−1 NaOH of receiving phase concentration.
