In order to investigate the influence of tri-sodium citrate, Na 3 Cit, and tri-potassium citrate, K 3 Cit, on the interaction of diphenhydramine-hydrochloride, DPH-HCl, and water, the volumetric, transport, and vapor liquid equilibria, VLE, properties were considered in this work. Thereby, density, speed of sound, and viscosity values for DPH-HCl drug in solutions containing Na 3 Cit, K 3 Cit, and H 2 O were measured in salt molality ranges of 0.05, 0.1, and 0.15 mol kg −1 and at T = 293.15, 298.15, and 303.15 K. Water activity and partial pressure of water data for systems of DPH-HCl + Na 3 Cit + H 2 O and DPH-HCl + K 3 Cit + H 2 O were also measured at 298.15 K. From these quantities, apparent molar volume, limiting apparent molar volume, apparent molar isentropic compression, limiting apparent molar isentropic compression, transfer standard volumes for DPH-HCl drug, and viscosity B-coefficients were calculated using the equations of Redlich−Meyer and Jones−Dole. The activities of water in these systems were correlated with the TNRF-mNRTL local composition based model.

The stability of amino acids in solutions containing electrolytes and the effect of ambient pH on their biological activity is one of the new research areas. In this research work, the volumetric and transport properties of ionic liquid (IL) aqueous solution with special performance of 1- (2-carboxyethyl) -3-methylimidazolium chloride ([HOOCEMIM][Cl]) were studied. The selected IL acts as an electrolyte with minimal toxicity and also allows the study of systems containing amino acids at acidic pH. In this work, the density, speed of sound and viscosity of binary and ternary solutions of IL in aqueous solution of amino acids in the structure of proteins, namely L-serine and L-threonine within IL molality range of (0.05, 0.07 and 0.09 mol kg-1) were measured at 298.15 K. From these quantities, apparent molar volume, limiting apparent molar volume, apparent molar isentropic compression, limiting apparent molar isentropic compression, transfer standard volumes for amino acids from water to the aqueous IL solutions and viscosity B-coefficients were calculated using the equations of Redlich–Meyer and Jones–Dole. Close examination of literature indicates that there is no data for water activity for solution of L-serine + H2O at 308.15 and 318.15 K. In this way water activity, osmotic coefficient and vapor pressure were measured and using the interaction parameters of Wilson, NRTL, NRF-NRTL and UNIQUAC models, activity coefficient values of L-serine calculated.

“…C 8 aromatics are crucial fundamental organic raw materials for the production of high-value poly(ethylene terephthalate) ionomer (PETI), which mainly consist of o -xylene, m -xylene, p -xylene, and ethylbenzene. , As the ethylbenzene in C 8 aromatics has a negative effect on the oxidation of m -xylene and p -xylene for PETI production, it is significant to separate the ethylbenzene from C 8 aromatic hydrocarbons . Besides, the obtained ethylbenzene can also be used as the primary raw material to produce high-value styrene.…”

Isobaric binary vapor−liquid equilibrium (VLE) data for ethylbenzene + ethyl benzoate, o-xylene + ethyl benzoate, m-xylene + ethyl benzoate, and p-xylene + ethyl benzoate, as well as the quinary VLE data for ethyl benzoate + o-xylene + mxylene + p-xylene + ethylbenzene, were measured at 101.33 kPa using a modified Rose still. The thermodynamic consistency test was implemented by using the Herington method. Moreover, the VLE data for ethyl benzoate + o-xylene, ethyl benzoate + mxylene, ethyl benzoate + p-xylene, and ethyl benzoate + ethylbenzene were correlated using the nonrandom two-liquid (NRTL) and universal quasichemical activity coefficient (UNIQUAC) models using the nonlinear least-square method. The obtained NRTL and UNIQUAC model parameters of the binary systems were utilized to predict the VLE data for the quinary system. It was shown that all the models showed a relatively small deviation from the experimental results, and the quinary predicted values obtained in this way agreed well with the experimental values, indicating that the experimental data were suitable for designing the extractive distillation process of ethyl benzoate with ethylbenzene and xylene isomers.
