ISOBARIC VAPOUR-LIQUID EQUILIBRIUM DATA OF THE SYSTEM ISOPROPANOL-METHYL ISOBUTYL KETONE AT (101.32, 66.67, AND 40.00 ± 0.02) KPa

Abstract (2. Language): 
Isobaric vapour-liquid equilibrium (VLE) data for the isopropanol - methyl isobutyl ketone system has been measured experimentally at (101.32, 66.67, and 40.00 ± 0.02) kPa. Consistency of the experimental results has been checked by Redlich-Kister, Broughton-Brearley, Black and Herington test methods. The equilibrium data was compared with UNIFAC and Margules models, two classical methods which have different calculation mechanism and which are methods widely used in this field. The results were illustrated as diagrams and tables, and the experimental data were contrasted with the calculated by evaluating the deviations. It was seen that the models exhibited an ineligibility with the experimental data, especially at low pressures, probably because of the insufficient pressure sensivity of the used model equations.

Abstract (Original Language): 
Izopropanol - metilsiklohekzan sistemine ait izobarik sıvı-buhar denge verileri (101.32, 66.67 ve 40.00 ± 0.02) kPa basınçlarda deneysel olarak elde edilmiştir. Deneysel verilerin tutarlılığı Redlich-Kister, Broughton-Brearley, Black and Herington test yöntemleriyle sınanmıştır. Denge verileri, bu alanda sıkça kullanılan ve farklı hesaplama yollarına sahip iki klasik metod olan UNIFAC ve Margules yöntemlerinden elde edilen verilerle karşılaştırılmıştır. Sonuçlar tablolar ve grafikler halinde sunulmuş, sapmalar değerlendirilmek suretiyle deneysel ve hesaplama sonuçları arasındaki farklar vurgulanmıştır. Muhtemelen model denklemlerin yetersiz basınç hassasiyeti dolayısıyla, elde edilen verilerin özellikle düşük basınçlarda, deneysel verilerden sapma gösterdiği görülmüştür.
