Experimental Measurements of Vapor–Liquid Equilibrium Data for the Binary Systems of Methanol + 2-Butyl Acetate, 2-Butyl Alcohol + 2-Butyl Acetate, and Methyl Acetate + 2-Butyl Acetate at 101.33 kPa

Abstract

The isobaric vapor–liquid equilibrium measurements for the systems of 2-butyl acetate with three chemicals (methanol, 2-butyl alcohol, methyl acetate) were determined respectively in a modified Rose still at 101.33 kPa. Thermodynamic consistency of the three binary vapor–liquid equilibrium data had been confirmed by Herington methods. The three groups of experimental data were all correlated with NRTL and Wilson models, respectively. The binary interaction parameters of both models had been obtained by the simplex method. The NRTL and Wilson equations showed low deviation with respect to the experimental data.

Experimental isobaric vapor–liquid equilibrium for ternary system of sec -butyl alcohol + sec -butyl acetate + N , N -dimethyl formamide at 101.3 kPa

“…The VLE data of the binary system sec-butyl alcohol (1) + secbutyl acetate (2) in the literature [1] and that in the ternary system excluding DMF are shown in Fig. 7.…”

“…However, Wang et al have not determined the existence of an azeotropic point, although the difference between vapor and liquid composition is nearly negligible [1]. Thus, "pseudo-azeotrope" is used to express the mixture of sec-butyl alcohol and sec-butyl acetate exactly in this work.…”

“…It is also used as feedstock of pesticides, wetting agents, polymerization additives and so on [1][2][3]. The traditional method of producing sec-butyl alcohol is indirect hydration of butylene, which uses sulfuric acid as catalyst and causes serious corrosion and low selectivity.…”

“…And VLE data of the system of sec-butyl alcohol (1) + sec-butyl acetate (2) + DMF (3) are vital for the simulation and design of an extractive distillation column. Up to now, only the isobaric VLE data of sec-butyl alcohol (1) + sec-butyl acetate (2) can be found in the open literature [1]. Those for sec-butyl alcohol (1) + DMF (3), sec-butyl acetate (2) + DMF (3) and sec-butyl alcohol (1) + sec-butyl acetate (2) + DMF (3) have not been reported in the literature.…”

Isobaric vapor–liquid equilibrium of the binary system sec-butyl acetate +para-xylene and the quaternary system methyl acetate +para-xylene +sec-butyl acetate + acetic acid at 101.3 kPa

“…Isobaric equilibrium experimental data have been reported in the open literature for the binary systems: MA + PX [15], MA + HAc [5], MA + SBA [21], HAc + PX [15], SBA + HAc [22]. For these five binary systems, the NRTL model interaction parameters were obtained from Li et al [22], Wang et al [21] and Wang et al [23]. Based on the binary interaction parameters of the NRTL activity coefficient model, VLE data of the quaternary system were predicted.…”
