| Summary: | 碩士 === 國立臺灣科技大學 === 化學工程系 === 88 === An isothermol flow microcalorimeter was utilized in this study to measure the excess enthalpies for the binary systems composed of 1-octanol + n-octane, + ethylbenzene, + anisole, + acetophenone, and + ethyl benzoate. Space the experiments were made at 298.15 K and 1atm.
The magnitudes of the excess enthalpies follow the order of acetophenone > anisole > ethyl benzoate > ethylbenzene > n-octane. It is consistent with the dipole moments of the dissimilar components.
The Redlich-Kister model correlated accurately the excess enthalpies. The Peng-Robinson (PR), the Patel-Teja (PT), and the Cubic Chain-of-Rotators (CCOR) equations of state were also employed to correlate the data. The calculated results from these three EOS were comparable when one adjustable binary interaction parameter was used. The improvements were substantial when two adjustable parameters were adopted in the CCOR EOS.
