“…The primary source and method for this value is not given. This point deviates substantially from values obtained from common prediction methods. n -Butyl acetate has published data for liquid heat capacity from around 290–360 K. − While many of these sources seem to agree, there are some significant outliers. In this work, liquid heat capacities from 193.15 to 373.15 K are measured and comparisons between these measurements and others can be found below. n -Hexyl acetate has one published liquid heat capacity data point at 298.15 K .…”

“…Mixtures of esters and hydrocarbons are commonly encountered in many industrial fields since several widely used solvents are among these types of compounds. Numerous studies have thus been published regarding the phase equilibria and thermodynamic properties of binary systems of esters with normal and branched alkanes. − Among those, an ester that features prominently is ethyl acetate, which is one of the most industrially employed short-chain esters. Mixtures of ethyl acetate with aromatic compounds and unsubstituted naphthenes (mainly cyclohexane) have also been significantly studied.…”

The density and isobaric phase equilibria of the binary system methylcyclopentane + ethyl acetate were investigated for the first time in this work. The density of the system was measured at 101 kPa from 288.15 to 308.15 K for the entire composition range thanks to a vibrating tube densimeter. Positive excess molar volumes were observed and correlated by using a Redlich–Kister equation. New isobaric vapor–liquid equilibrium data for the system methylcyclopentane + ethyl acetate were measured by means of a recirculation ebulliometer. The phase equilibrium was measured at 25, 50, and 101.3 kPa. Equilibrium compositions were determined indirectly from density measurements of the liquid and condensed vapor phases. Some additional density and vapor–liquid equilibrium data measurements for the binary system ethyl acetate + methylcyclohexane were performed for comparison with previously published results and validation of the experimental protocol. The methylcyclopentane + ethyl acetate binary mixture displays pronounced positive deviations from ideality and a positive azeotrope. Three thermodynamic consistency tests were employed to validate the produced data set. The reported data were successfully correlated by the NRTL model, and the modified UNIFAC predictive model was also used. UNIFAC provides a very good description of the phase behavior at 101.3 kPa, whereas predictions are less accurate at low pressures (25 and 50 kPa).

“…The situation is slightly better for the densities of systems of ethyl acetate + branched saturated hydrocarbons. The densities of the binary system ethyl acetate + 2,2,4-trimethylpentane were reported at 298.15 K [18,19] and 303.15 K [20], while the excess molar volumes of four binary ethyl acetate + branched light alkanes were published at 298.15 K [21].…”

Vapor–liquid equilibrium (VLE) and density data for binary systems of branched alkanes + ethyl acetate are scarce in the literature. In this study, the binary mixtures 3-methylpentane + ethyl acetate and 2,3-dimethylbutane + ethyl acetate were investigated. Density measurements at atmospheric pressure were performed using a vibrating tube density meter at 293.15, 298.15 and 303.15 K. Large and positive excess molar volumes were calculated and correlated using a Redlich–Kister-type equation. Isobaric VLE data at 101.3 kPa were obtained using a Gillespie-type recirculation ebulliometer. Equilibrium compositions were determined indirectly from density measurements. The experimental data were checked for consistency by means of the Fredenslund test and the Wisniak (L-W) test and were then successfully correlated using the NRTL model. The newly studied binary systems display high deviations from ideality and minimum boiling azeotropes, the coordinates of which are reported in this work.
