The Vapor-Liquid equilibrium composition and temperature for the binary system, methyl acetate-cyclohexane , was measured 760mmHg. A continuous circulating equilibrium still was constructed in which the pressure and temperature were precisely controlled, over the complete range of the experimental compositions. The experimental data was corrected by the reduction method. The random errors were removed from the experimental data. Wilson parameters and constants were calculated from the experimental data of this work, and partial molar interaction energy and molecular interaction energy were estimated from the wilson constants. TPTT parameters, constants, partial molar interaction energy, molecular interaction energy varied considerably with respect to temperature and liquid composition. The different variations are probably due to the assumption of the wilson equation.
Sieve Plate Column에서 Cyclohexane-Toulene系의 分溜에 關한 硏究
柳洪烈,金宗植 啓明大學校 産業技術硏究所 1986 産業技術硏究所 論文報告集 Vol.8 No.-
Cyclohexane-Toluene mixtures were distilled in a sieve plate column to study the sample compositions at each plate, effect of reflux ratio, purity of final products theretical, actual numbers of plates, and the column efficiency. These data were correlated with several theoretial equations, effects of temperature, and feed composition and reflex ratio on distillation efficiency was examined to optimize the distillation.
