초록
298.15 K및 1 atm하에서 2성분계 {1,2-dichloropropane+1,3-dioxolane} 및 {1,2-dichloropropane+1,4-dioxane}에 대해서 과잉 몰부피와 과잉 몰엔탈피를 측정하였다. 과잉 몰부피의 경우 {1,2-dichloropropane+1,3-dioxolane}계는 전체 조성 범위에서 음의 편차를 나타내며, {1,2-dichloropropane+1,4-dioxane}계는 전 조성범위에 대해 양의 편차를 나타내었다. 과잉 몰엔탈피의 경우 {1,2-dichloropropane+1,3-dioxolane}계 및 {1,2-dichloropropane+1,4-dioxane}계 모두 전 조성범위에서 음의 편차를 나타내었다. VmE의 경우 분자구조의 차이 및 분자크기에 따라 이상상태로부터 각각 양과 음의 편차를 보여주었으며, HmE의 경우는 1,2-dichloropropane의 -Cl기와 1,3-dioxolane및 1,4-dioxane의 O< 기 사이의 쌍극자-쌍극자 상호작용에 따라 음의 편차를 보여주고 있다. 또한 그 결과를 Redlich-Kister식에 Nelder-Mead's simplex pattern search method를 사용하여 파라미터를 계산하였다.
This paper reports experimental excess molar volumes VmE using a digital vibrating-tube densimeter and excess molar enthalpies HmE by means of an isothermal microcalorimeter with a flow mixing cell for the binary mixtures {1,2-dichloropropane+1,3-dioxolane} and {1,2-dichloropropane+1,4-dioxane} at 298.15 K under atmospheric pressure. The mixture of {1,2-dichloropropane+1,3-dioxolane} has negative VmE over the entire composition range with exception of 1,4-dioxane, which has been shown to be positive. The cyclic molecular shape of 1,4-dioxane is not ideal to accept the halogenated hydrocarbon, resulting in an increase in the molecular distance. The consequent loosening of intermolecular intersections is also responsible for the positive values of VmE, with the exception of 1,3-dioxolane, due to its smaller molecular size. The excess enthalpies of all these mixtures were found to be positive over the entire composition range. These negative deviations from ideal behavior are probably due to dipole and dipole interaction between Cl and O molecules. The values of excess molar properties were fitted by the Redlich-Kister equation using Nelder-Mead’s simplex pattern search method.
