Prediction and experimental verification of the effect of salt on the vapour–liquid equilibrium of ethanol/1-propanol/water mixture

Review and Thermodynamic Modeling with NRTL Model of Vapor–Liquid Equilibria (VLE) of Aroma Compounds Highly Diluted in Ethanol–Water Mixtures at 101.3 kPa

“…The discussion concludes with a comparison between: (1) the representation of the equilibrium data using the set of parameters calculated in this work, from data at high dilution regarding the aroma compounds (Table and Table ), and (2) the one obtained with parameters fitted to data for binary and ternary systems, in which the aroma compounds are present at high concentrations. These parameters are available in the literature for some aroma compounds. ,− ,, However, according to the writing of eqs and , they cannot be used directly for two reasons: (i) the formalisms to evaluate the temperature dependence of the interaction parameters c ij and τ ij are not the same of this work, and (ii) the nonrandomness parameters c ij 0 is different from the value set in this work (0.3), which does not make possible the conversion of the parameters G ij and τ ij in the different formalisms.…”

Consequently, new interaction parameters are estimated from experimental data by following an analogous procedure to that described in section 3.1 Information on the aroma compounds considered, the data references 8,75−107 as well as the temperature and composition intervals are summarized in Table 7 for binary systems (aroma compound−ethanol and aroma compound−water) and in Table 8 for ternary systems T Calc k and K i Calc k are computed with the Bubble Temperature algorithm of the Simulis Thermodynamics package by fixing the pressure (P) and composition in the liquid phase (x) to the experimental data.…”

The Structures of ZnCl2-Ethanol Mixtures, a Spectroscopic and Quantum Chemical Calculation Study

“…When it comes to electrolytes, their solvation in alcohols and aqueous alcohol solutions are of great significance in many industrial and natural processes [ 22 , 23 , 24 ]. So, the mixtures of alcohols with organic or inorganic salts have been vastly investigated, mostly focusing on understanding the physicochemical properties of the systems [ 22 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ]. Of particular interest, it has been reported that the dissolution of some salts in certain alcohols in appropriate molar ratios leads to a significant drop in freezing points with respect to the composing pure components, forming the neoteric class of solvents coined as deep eutectic solvents (DESs) [ 23 , 24 , 34 ].…”
