Vapor–liquid equilibria and excess volumes of the binary systems ethanol+ethyl lactate, isopropanol+isopropyl lactate and n-butanol+n-butyl lactate at 101.325kPa

Kinetic study for esterification of lactic acid with ethanol and hydrolysis of ethyl lactate using an ion-exchange resin catalyst

“…The activity coefficients of the components in the liquid phase were calculated by using the UNIQUAC equation. For the non-reactive binary systems UNIQUAC parameters were taken from the literature [15,16]. In the case of the reactive binary systems, vapor liquid equilibrium (VLE) data were predicted by UNIFAC, and the estimated data were used to obtain the UNIQUAC parameters [17].…”

Vapor–Liquid Equilibrium of Ethyl Lactate Highly Diluted in Ethanol–Water Mixtures at 101.3 kPa. Experimental Measurements and Thermodynamic Modeling Using Semiempirical Models

“…To our knowledge vapor−liquid equilibrium data for ethyl lactate highly diluted in ethanol− water mixtures at 101.3 kPa have not been reported in the literature. Only binary equilibrium data have been generated: (1) at isobaric conditions for the ethyl lactate (EL)−ethanol (Et) system at 101.3 kPa 35 and 2 36 Isobaric equilibrium data for the ethyl lactate (EL)−lactic acid (LA)−ethanol (Et)−water (W) quaternary system at 101.3 kPa has also been reported. 37 For the binary measurements, the whole liquid composition range of ethyl lactate was considered, x EL = (0 to 1) mole fraction, whereas for the quaternary system, the interval is more reduced, x EL = (0.02 to 0.20) mole fraction.…”

Isobaric vapor–liquid equilibria for the quaternary reactive system: Ethanol+water+ethyl lactate+lactic acid at 101.33kPa

“…the values obtained from the literature, i.e. : ethanol + water [19], ethanol + ethyl lactate [14] and water + lactic acid [2,3]. The rest of the binary interaction parameters were obtained directly from the quaternary VLE data correlation.…”

“…As an additional purity check, some physical properties of the pure components were measured and compared with values reported in the literature. Results were presented in a previous publication [14].…”
