Binary LiquidMINUS SIGN Liquid Equilibria of ?-Valerolactone with Some Hydrocarbons
Popis výsledku v původním jazyce
Liquid-liquid equilibrium data in binary systems ?-valerolactone + hydrocarbon (n-heptane, n-decane, n-dodecane, cyclohexane and 2,4,4-trimethyl-1-penetene) were determined by direct analytical and cloud-point methods. The experimental data were smoothedby the extended scaling law equation which respects nonclassical behavior of fluid mixtures in critical loci. The NRTL equation's parameters were evaluated from the data obtained, as well. Since the molecule of ?-valerolactone retains quite high dipolemoment, the acquired experimental data on liquid-liquid equilibrium were used for testing of prediction capabilities of the perturbed-chain polar SAFT equation of state (PCP-SAFT) in comparison to the original PC-SAFT model. Vapor pressures of ?-valerolactone in the temperature range from 264 K to 313 K and its liquid densities at temperatures from 288 K to 363 K were measured and utilized for evaluation of the PCP-SAFT and PC-SAFT parameters. It was found that prediction of liquid-liqui
