ABSTRACT

Vapor-liquid equilibrium (VLE) data in the two binary methyl 2-methyl-2-butyl ether (tert-amyl methyl ether, TAME) + 2-methyl-2-propanol (tert-butanol) and TAME + 2,2,4-trimethylpentane (isooctane) systems and in the ternary TAME + tert-butanol + isooctane system are reported. The data were measured isothermally at (318.13, 328.20, and 338.28) K covering the pressure range from (15 to 51) kPa. The binary VLE data were correlated using the Wilson and nonrandom two-liquid (NRTL) equations by means of a new algorithm; resulting parameters were then used for the calculation of phase behavior in the ternary system and for subsequent comparison with experimental data.
