Liquid-Liquid Equilibria for the Ternary Systems of 4-Methyl-1,3-dioxolan-2-one+1,4-Dimethylbenzene plus Octane, Decane, or Dodecane and the Ternary Systems of Acetonitrile plus Morpholine plus Octane, Decane, or Dodecane at 313.15 K or 298.15 K

Abstract

The phase behavior of a temperature-dependent multicomponent system was investigated for ternary systems comprising a polar aprotic solvent, a solubility mediator, and aliphatic hydrocarbons such as octane, decane, or dodecane. The experimental tie-line composition and binodal composition were obtained for the ternary system of 4-methyl-1,3-dioxolan-2-one + 1,4-dimethylbenzene + octane, decane, or dodecane and the ternary system of acetonitrile + morpholine + octane, decane, or dodecane at two different temperatures, 298.15 K and 313.15 K. The distribution ratios of 1,4-dimethylbenzene and morpholine were determined, and the experimental tie-line results were adequately correlated using the nonrandom two-liquid (NRTL) activity coefficient model by utilizing the obtained binary interaction parameter.
