Název v původním jazyce

Limiting activity coefficients in binary mixtures of 1-alkanols and ethylbenzene

Popis výsledku v původním jazyce

Limiting activity coefficients in binary mixtures of six lower 1-alkanols (C1?C6) and ethylbenzene were determined employing alternatively the techniques of inert gas stripping and comparative ebulliometry. For each case, the suitable technique was chosen on the basis of the limiting relative volatility of the solute. Measurements were typically carried out at four temperatures covering a range of 30K and were done with a good precision (1?3%). The new data were compared with available literature information on both the activity coefficient and calorimetric partial molar excess enthalpy at infinite dilution. All the critically evaluated information was merged and processed simultaneously to produce the recommended temperature dependences of the limiting activity coefficients. The performance of leading prediction methods (UNIFAC, modified UNIFAC, ASOG, MOSCED, DISQUAC) was further examined using this data.
