ABSTRACT

Isobaric binary vapor liquid equilibrium (VLE) data were measured for the 1-methyl-4-(1-methylethenyl)-cyclohexene (d-limonene) + {ethanol, propan-1-ol, propan-2-ol, butan-1-ol, pentan-1-ol, or hexan-1-ol} systems at 40 kPa. A low pressure dynamic still was used for the measurements. The experimental data were regressed using the nonrandom two-liquid (NRTL) and Wilson activity coefficient models. Both models correlated the data well. The 1-methyl-4-(1-methylethenyl)-cyclohexene + {butan-1-ol or pentan-1-ol or hexan-1-ol} systems exhibit a minimum temperature azeotrope. The 1-methyl-4-(1-methylethenyl)-cyclohexene + {ethanol or propan-1-ol or propan-2-ol} systems show the largest positive deviation from Raoult's law, and these systems exhibit no azeotropic behavior.
