Isothermal v.l.e. and excess molar Gibbs energy of binary and ternary mixtures containing diisopropyl ether,n -heptane and isopropanol at T= 313.15 K

Isobaric Vapor–Liquid Equilibria and Extractive Distillation Process Design for Separating Methanol and Methylal

“…The root-mean-square deviation (RMSD) and the average absolute deviation (AAD) is used to evaluate specific differences between experimental and calculated values. RMSD is calculated by eqs and and AAD is given by eqs and . …”

Thermodynamics of Octane-Enhancing Additives in Gasolines: Vapor−Liquid Equilibrium of Ternary Mixtures Containing Di-isopropyl Ether or Cyclohexane and 1-Hexene + Benzene at 313.15 K

“…In previous papers, we published the study of binary and ternary systems containing MTBE 1-6 and the substitution hydrocarbons n-heptane, cyclohexane, 1-hexene, and benzene at 313.15 K. Also, some results with TAME 7-10 and DIPE [11][12][13][14][15][16] have already been published.…”

“…Di-isopropyl ether (DIPE) could be use as a blending agent in the formulation of the new unleaded gasolines. In previous papers, we published the study of binary and ternary systems containing MTBE − and the substitution hydrocarbons n -heptane, cyclohexane, 1-hexene, and benzene at 313.15 K. Also, some results with TAME − and DIPE − have already been published.…”

Vapor–Liquid Equilibria Measurements for Di-n-Propyl Ether and Butyl Ethyl Ether with n-Heptane

“…This has been largely due to industrial interest in these ethers as fuel additives to increase octane ratings and decrease automotive emissions associated with these fuels. Particular attention has been given to mixtures of hydrocarbons with methyl tert -butyl ether (MTBE), − tert -amyl methyl ether (TAME), ,− ethyl tert -butyl ether (ETBE), ,− and di-iso-propyl ether (DIPE); , an extensive review of vapor–liquid equilibrium (VLE), liquid–liquid equilibrium (LLE), and excess properties for industrially relevant ethers with nonpolar solvents is also available in the literature . This plethora of available data highlights the drive for generating experimental phase equilibrium data for specific industrial applications.…”

“…To our knowledge, no data has been measured for the constitutional isomers of medium length (C 6 to C 9 ) linear ethers with a common n -alkane. Within the existing literature, however, there are multiple data sets for the branched C 6 ethers (i.e., ETBE, ,,, TAME, ,,, and DIPE , ) with n -heptane, but not for their linear chain isomers. This presents an ideal opportunity to systematically expand the body of available data for structural isomers with a common second component, as has been the aim of this series of data papers.…”
