GC 머무름시간을 이용한 알데히드 동족체의 열역학적 상수 측정 = Determination of Thermodynamic Constants for Homologous Aldehydes Using GC Retention Times

다국어 초록 (Multilingual Abstract)

Thermodynamic parameters of a homologous serious of n-aldehydes were determined by using gas chromatographic retention data, distribution coefficient and following relationships : ??, ??, ??. From the retention data at several temperatures under isothermal conditions, a plot of lnk versus 1/T was generated, and the enthalpy and entropy changes were calculated from the slope and intercept, respectively. The standard free energy value change calculation of the transition between the stationary phase and the mobile phase results in negative value in the most cases, indicating a spontaneous process. The relationship between the standard free energy and the number of carbon atoms in the homologue was linear under isothermal conditions, and the linear relationship between free energy change and temperature was accurately determined. The information applicable to the prediction of retention times using numerical simulation was obtained.
