Experimental isobaric vapour-liquid equilibrium data for binary systems of {sec-butyl acetate (SBAC) + acetamide} and {sec-butyl alcohol (SBA) + acetamide} and the ternary system of (SBAC + SBA + acetamide) at 101.3 kPa

Isobaric vapour-liquid equilibrium of α-terpineol highly diluted in hydroalcoholic mixtures at 101.3 kPa: Experimental measurements and thermodynamic modeling

“…The L-W test of Wisniak [78] The thermodynamic consistency of our data was additionally evaluated using the L-W test developed by Wisniak [78], which is now routinely employed by many authors [82][83][84]. The test can be described by the following expressions: 31 in which, for a pure component i, /K is the boiling temperature, /J•K -1 is the entropy of vaporization, with , and /J is the vaporization enthalpy.…”

Isobaric Vapor–Liquid Equilibrium Data at 101.3 kPa for the Binary System Acetamide + N,N-Dimethyl Formamide and the Quaternary System sec-Butyl Alcohol + sec-Butyl Acetate + Acetamide + N,N-Dimethyl Formamide

“…Extractive distillation is an effective process to separate an azeotropic or close boiling system by altering the relative volatility with entrainers. 10,11 In addition, the entrainer is key to the feasibility of an extractive distillation process. An excellent entrainer should have some characteristics, such as high selectivity, solubility and thermostability, low melting point, moderate boiling point, and so on.…”

“…Vapor−liquid equilibrium (VLE) data are the basis for the design and simulation of extractive distillation columns. The isobaric VLE data of the ternary systems SBA + SBAC + DMF, 17 SBA + SBAC + DMAC, 18 SBA + SBAC + DMSO, 19 and SBA + SBAC + acetamide 10 and the quaternary systems SBA + SBAC + DMF + DMAC, 20 SBA + SBAC + DMF + DMSO, 21 and SBA + SBAC + DMSO + DMAC 22 have been measured by our group. Because DMSO has a lower thermostability, 23 explosion hazard exists in long-term operation.…”

“…Our previous work shows that acetamide is a promising entrainer. 10 However, it has some drawbacks of high boiling and melting points, leading to a high requirement on heating utility and difficulties in transport and storage, respectively. In contrast, DMF has a higher solubility and lower melting and boiling points, but it performs worse than acetamide in altering the relative volatility.…”

“…In contrast, DMF has a higher solubility and lower melting and boiling points, but it performs worse than acetamide in altering the relative volatility. 10 VLE data of DMF + acetamide and SBA + SBAC + acetamide + DMF were measured at 101.3 kPa.…”
