Correlation of Vapor-Liquid Equilibrium Data for Acetone-Water System.

Effect of Data Type on Thermodynamic Model Parameter Estimation: A Monte Carlo Approach

“…It is a Binary interaction parameter used in Figure 6 for the "BI-NARY 01" curve; parameters regressed using data from Kojima et al (1968). b Binary interaction parameter used in Figure 6 for the "BINARY 02" curve; parameters regressed using data from Eduljee (1958). important to mention that the differences of the average absolute deviation between these two parameter sets are not very large, a result that is in agreement with the small difference in their respective SEE values.…”

“…Several sources were chosen with the purpose of studying the effect of changing the experimental data source for one of the binary systems and looking at the effect of having different variances of the parameters regressed. The experimental vapor-liquid data for the system acetone + water were obtained from Eduljee (1958), also reported by Gmehling and Onken (1977), and the data for the liquid-liquid chloroform + water system are from Stephenson (1992). All the experimental data just mentioned above were used to regress the UNIQUAC binary interaction parameters that were used for predicting the equilibrium of the system in a process operation.…”

“…The data for the binary liquid-liquid system 1,1,2-trichloroethane + water were taken from Stephenson (1992). Gmehling and Onken (1977) report experimental vapor-liquid equilibrium data for the system acetone + water; the data from Eduljee (1958) and Kojima et al (1968) were used.…”

Mechanistic insight into the evaporative crystallization of two polymorphs of nitrofurantoin monohydrate

“…In an earlier report, the solvent combination used for preparing pure monohydrate I was water and acetone (volume ratio 1:2) [13]. The water activity in this water-acetone mixture was calculated to be 0.801, using the equations from Eduljee et al (1958) [45]. To gain a deeper understanding of the water activity effect on the crystallization, five other solvent systems with different water activity values were also selected.…”

Metabolically engineered Caldicellulosiruptor bescii as a platform for producing acetone and hydrogen from lignocellulose

“…One advantage to producing acetone in an extreme thermophile is direct removal of acetone at the elevated temperatures without the need for gas stripping. Acetone‐water phase equilibria data (Eduljee, Kumarkrishnaroo, & Rao, 1958) and Aspen Plus software were utilized to determine a feasible in situ separation concept which would allow the fermentation broth to remain at 20 g/L (344 mM), while continuing to produce acetone, resulting in an “effective titer” in excess of the toxicity limit. A titer of 20 g/L (2.0 wt%) acetone is only 0.64 mol% of the liquid phase.…”
