Experimental and Predicted Excess Molar Enthalpies of the Ternary System tert-Butyl Methyl Ether + 1-Pentanol + Decane at 298.15 K

“…Experimental values of for { x tert -butyl methyl ether (MTBE) + (1 − x )decane} and { x 1-pentanol+ (1 − x )decane} are listed in Table . The experimental data of excess molar enthalpies for the binary mixture { x tert -butyl methyl ether (MTBE) + (1 − x )1-pentanol} were reported in an early paper . The experimental data of corresponding to the binary mixtures { x tert -butyl methyl ether (MTBE) + (1 − x )1-pentanol} and { x tert -butyl methyl ether (MTBE) + (1 − x )decane} were fit to the variable-degree polynomials suggested by Redlich−Kister of the form and lower deviations for the mixture { x 1-pentanol+ (1 − x )decane} were obtained by fitting experimental data to the equation suggested by Myers−Scott: …”

“…The present work reports experimental excess molar enthalpies of { x 1 tert -butyl methyl ether (MTBE) + x 2 1-pentanol + (1 − x 1 − x 2 )decane}, { x tert -butyl methyl ether (MTBE) + (1 − x )decane}, and { x 1-pentanol+ (1 − x )decane} at 298.15 K and atmospheric pressure. The excess molar enthalpies for the binary mixture { x tert -butyl methyl ether (MTBE) + (1 − x )1-pentanol} were reported in earlier work . The measurement of excess molar enthalpies was carried out using a Calvet microcalorimeter.…”

Determination of excess molar enthalpies of the ternary system methyl tert-butyl ether+1-pentanol+nonane at 298.15K

“…The present work reports experimental excess molar enthalpies for the ternary system {x 1 methyl tert-butyl ether + x 2 (1-pentanol) + (1 − x 1 − x 2 ) nonane} and the involved binary mixtures {x methyl tertbutyl ether + (1 − x) nonane} and, {x (1-pentanol) + (1 − x) nonane} at the temperature of 298.15 K and atmospheric pressure. The excess molar enthalpies for the binary mixture {x methyl tert-butyl ether + (1 − x) (1-pentanol)} was reported in an earlier work [1].…”

“…The excess enthalpies for the three involved binary mixtures [1] are positive over the whole range of composition. The endothermicity of these mixtures suggests then that the positive contributions to the excess enthalpy, namely the breaking of interactions are energetically more important than the negative contribution, which is a specific interaction between unlike molecules.…”
