“…The identification of the node indices was performed using the methodology employed by Kiva et al depending on the type of singular point in the mixture and the direction of the boiling temperature increase. To achieve this identification, the calculation of the non-reactive residual curve maps of the quaternary system at 101.32 kPa (Figure ) were performed using the methodology implemented in previous works . The indices identified for the nodes of the quaternary system are listed in Table .…”

“…To achieve this identification, the calculation of the non-reactive residual curve maps of the quaternary system at 101.32 kPa (Figure 9) were performed using the methodology implemented in previous works. 32 The indices identified for the nodes of the quaternary system are listed in Table 10. Thus, by applying eq 9 with the identified indices, it was verified that the behavior of the system with four azeotropes is consistent with the azeotropic rule.…”

This work focuses on studying the vapor–liquid–liquid equilibrium (VLLE) of the ternary system 1-propanol–propyl propanoate–water. Experiments were carried out under isobaric conditions at 80.00 and 101.32 kPa by using a Fischer Labodest VLLE 602 equilibrium cell with an ultrasonic probe in the boiling chamber. According to results, the data sets exhibit the presence of binary and ternary heterogeneous azeotropes. Besides, aiming to obtain a unique set of thermodynamic parameters to predict the behavior of the whole system involved in the propyl propanoate synthesis (propionic acid–1-propanol-propyl propanoate–water), the phase equilibria of the quaternary system were also studied. To correlate the set of binary parameters for NRTL-HOC and UNIQUAC-HOC thermodynamic models, literature data on binary and ternary vapor–liquid equilibrium (VLE), liquid–liquid equilibrium (LLE), and VLLE data from this work were used altogether. The obtained results from correlated models depict good agreement with experiments, with average deviations lower than 1.83 K and 3.57% in temperature and molar composition, respectively. The thermodynamic consistency of experimental data was validated by means of the McDermott–Ellis method, the Wisniak method, and topological analysis. The new set of thermodynamic parameters can be used to simultaneously represent the behavior of VLE, LLE, and VLLE in the propyl propanoate production process.

“…LLE data for water + lactic acid + butanol were studied experimentally at 298.2 K and 95 kPa by Domingues and colleagues . However, there are no sufficient data reports of liquid–liquid equilibrium (LLE) in the open literature regarding butyl lactate + water or mixtures of l -lactate butyl , that provide enhanced phase equilibrium information necessary for an appropriate process design aiming to synthesize butyl lactate while simultaneously removing water from the system . The potential presence of water coexisting with butyl lactate in the bottoms requires further investigation.…”

“…In an experimental study 68,80 that provide enhanced phase equilibrium information necessary for an appropriate process design aiming to synthesize butyl lactate while simultaneously removing water from the system. 12 The potential presence of water coexisting with butyl lactate in the bottoms requires further investigation. It is relevant to comprehend this equilibrium and ascertain whether the final design requires additional equipment to effectively eliminate residual water, which may compromise the properties of the target product.…”

This work presents the isobaric liquid−liquid equilibrium (LLE) data for the binary mixtures of butyl L-lactate + water and butyl lactate + water, which were measured at 74.6 kPa in the temperature range from 283 to 343 K. The composition of the samples from LLE experiments was determined by gas chromatography using a Shimadzu 2010 plus with a thermal conductivity detector (TCD). The nonrandom two-liquid (NRTL) and universal quasichemical activity coefficient (UNIQUAC) models were applied to correlate the experimental data and to determine the binary interaction parameters. Both models generate data that correlates well with the observed experimental data and the parameter determination was proved to be consistent through topological analysis of the generated G M /RT function, such that the correlations can be applied to the separation process design for the synthesis of n-butyl lactate via reactive distillation.
