Abstract

It is known that almost all cyclohexane molecules are chair form in liquid state. Therefore, only chair form is considered in formulating the partition function for liquid cyclohexane, according to the Transient State Theory of Significant Liquid Structure proposed by Pak, Ahn and Chang. The thermodynamic quantities such as molar volume, vapor pressure, entropy of vaporization and compressibility of the liquid are calculated. The results are in good agreement with experimental values.

싸이클로핵산의 분자는 액체상태에서 대부분이 chair form으로 되어 있음이 알려져 있다. 이 사실로 부터 싸이클로핵산의 액체는 Chair form 만으로 되어있다는 가정하에 액체구조의 천이상태이론을 적용시켜 상태함을 구하고 이로부터 싸이클로핵산의 몰부피, 증기압, 한계점, 증발엔트로피 및 압축률 등의 열역학적 량을 계산한 결과 측정치와 잘 맞는 값을 얻었다.
