“…3. The mean deviations of V E are 0.0023 and 0.0079 g/cm 3 for systems DMC (1) + ethanol (2) and DMC (1) + 2,2,4 trimethylpentane (2), respectively. The measured V E at 298.15 K show positive deviations from ideal behavior over the whole composition range.…”

“…As far as we know, there are no ternary VLE data at 333.15 K and no excess property data at 298.15 K for DMC + ethanol + 2,2,4-trimethylpentane. We reported earlier VLE data at 333.15 K for the systems DMC (1) + ethanol (2), DMC (1) + 2,2,4-trimethylpentane (2) and and n D values at 298.15 K for ethanol (1) + 2,2,4-trimethylpentane (2) [6][7][8]. The binary VLE data and excess properties in this work are supplements of sub-binary data for ternary system DMC + ethanol + 2,2,4 trimethylpentane.…”

“…The results are lower levels of carbon monoxide and unburned hydrocarbons in auto exhaust. Today, methyl tert-butyl ether (MTBE) dominates the market, but the insufficient supply of this ether and anxiety of contamination of ground water are the reason for the interest in heavier ethers and other substitutes [1,2]. Recently, environmentally friendly di-methyl carbonate (DMC) is considered as a suitable gasoline additive and ethyl tert-butyl ether (ETBE), tert-amyl methyl ether (TAME) and di-isopropyl ether (DIPE) are also considered as the most possible candidates among ether compounds.…”

“…matography (HSGC). Densities ( ) and refractive indices (n D ) at 298.15 K for the binary systems DMC (1) + ethanol (2), DMC (1) + 2,2,4-trimethylpentane (2) and the mentioned ternary system were also measured by using a digital vibrating tube densimeter and a precision digital refractometer. The ternary system DMC + ethanol + 2,2,4-trimethylpentane was chooser because DMC and ethanol are possible of green octane boosters and 2,2,4-trimethylpentane is a major component of gasoline.…”

This work forms part of a broader study that describes a methodology to validate experimental data of phase equilibria for multicomponent systems from a thermodynamic‐mathematical perspective. The goal of this article is to present and justify this method and to study its application to vapor–liquid equilibria (VLE) and vapor–liquid–liquid equilibria (VLLE), obtained under isobaric/isothermal conditions. A procedure based on the Gibbs‐Duhem equation is established which presents two independent calculation paths for its resolution: (a) an integral method and (b) a differential method. Functions are generated for both cases that establish the verification or consistency of data, δψ for the integral test and δζ for the differential approach, which are statistically evaluated by their corresponding average values [ δtrueψ¯, δtrueζ¯], and the standard deviations [ strue(δψtrue), strue(δζtrue)]. The evaluation of these parameters for application to real cases is carried out using a set of hypothetical systems (with data generated artificially), for which the values are adequately changed to determine their influence on the method. In this way, the requirements of the proposed method for the data are evaluated and their behavior in response to any disruption in the canonical variables (p,T, phase compositions). The conditions for thermodynamic consistency of data are: δtrueψ¯<2, strue(δψtrue)<0.2, δtrueζ¯<5, and s(δξ)<0.2. In systems with VLLE, in addition to the previous criteria, must occur that: δxLLE<0.05 and δTLLE<0.5 K. The new proposed method has been tested with a set of 300 experimental binary systems, biphasic and triphasic, obtained from published bibliography, and the results are compared with those of other tests commonly used for testing thermodynamic consistency. The results show that the greater rigor of the proposed method is mainly due to the simultaneous verification of various independent variables. As a result, the conditions for the new test are verified for fewer systems than using other tests mentioned in the literature (i.e., Fredenslund‐test and direct of Van Ness). Its unique application is sufficient to ensure the consistency of experimental data, without using other tests. © 2017 American Institute of Chemical Engineers AIChE J, 2017
