概要

• 論文の詳細を見る

• This study presents a new ebulliometer which is able to compensate for the vapor hold-up problem commonly experienced when measuring vapor–liquid equilibria. Firstly, the influence of the vapor hold-up was examined by measuring the boiling points for the ethanol + toluene system at 53.33 kPa, and it was confirmed that the vaporization coefficient of the newly-developed ebulliometer was 2.2%. Secondly, the boiling points of three binary systems of ethanol + toluene, ethanol + cyclohexane, and benzene + cyclohexane, were determined in the range of 53.33 to 98.66 kPa. In addition, the experimental boiling point data were satisfactorily correlated using the NRTL equation. Finally, the determined NRTL parameters were evaluated by calculating the vapor–liquid equilibria under the same conditions as the thermodynamically reliable values in the literature.
