Vapor–liquid equilibria for the binary systems decane + 1,1-dimethylethyl methyl ether (MTBE) and decane + 1,1-dimethylpropyl methyl ether (TAME) at 308.15, 318.15 and 328.15 K

Vapor–liquid equilibrium (VLE) data are reported for the binary mixtures formed by decane and the branched ethers 1,1-dimethylpropyl methyl ether ( tert-amyl methyl ether or TAME) and 1,1-dimethylethyl methyl ether ( tert-butyl methyl ether or MTBE). A Gibbs–Van Ness type apparatus was used to obtai...

Description
Summary:Vapor–liquid equilibrium (VLE) data are reported for the binary mixtures formed by decane and the branched ethers 1,1-dimethylpropyl methyl ether ( tert-amyl methyl ether or TAME) and 1,1-dimethylethyl methyl ether ( tert-butyl methyl ether or MTBE). A Gibbs–Van Ness type apparatus was used to obtain total vapor pressure measurements for the decane+MTBE and decane+TAME systems as a function of composition at 308.15, 318.15 and 328.15 K. Both systems show a nearly ideal behavior. VLE data are analyzed together with excess enthalpy ( H m E) data previously obtained at 298.15 K for these mixtures. The UNIQUAC model is used to correlate VLE and H m E data and the original UNIFAC group contribution model and the modified UNIFAC (Dortmund model) are used to predict VLE and H m E data for the binary systems decane+MTBE and decane+TAME.
