Abstract
액상 혼합물의 용액거동은 혼합물 구성분자들 사이의 인력에 의존하며, 혼합시의 과잉 몰부피(VE)는 따라서 각 구성 성분간의 상호관계를 이해하는데 뿐만 아니라 열역학적 설계에도 중요한 의미를 지니다. 본 실험에서는 25℃ 등온 하에서 cyclohexane-alcohol(C1-C4)혼합계의 과잉 몰부피를 digital vibrating tube densimeter를 이용하여 측정하였다. 본 실험에서 측정한 모든 cyclohexane-alcohol 혼합계의 과잉 몰부피값은 모두 이상용액으로부터 양의 편차를 보였으며, cyclohexane-methanol 혼합계에서는 불용영역을 나타내었다. 실험으로 얻은 데이터는 6개의 매개변수를 사용한 Redlich-Kister 다항식을 이용하여 합치시켜 보았으며, 실험값과의 평균편차(Sd)는 약 0.009㎤/mol 미만이었다.
Solution behavior of liquid mixtures are depend on the interactions of constituent molecules in solution, excess molar volume(VE) is therefore very important in the thermodynamic design as well as understanding the relation between constituent components. In this work, excess molar volumes have been measured for binary mixtures of cyclohexane-alcohol(C1-C4)at 298.15K by using digital vibrating tube densimeter. Excess molar volume values show positive deviation from the ideality in all the measured cyclohexane-alcohol systems and expecially cyclohexane-methanol mixture has immiscible region. Experimental data were fitted with 6 parameter Redlich-Kister equation, and their standard deviations(Sd), from the experimental data were less than 0.009㎤/mol.
