Data20032003-09-25Vapor-Liquid Equilibria for the Binary Mixture alpha-Pinene + OctaneIsothermal and isobaric vapor-liquid equilibria (VLE) were measured for the binary mixture alpha-pinene + octane at the temperatures (348.15, 363.15, 383.15) K and at the pressures (26.66, 53.33) kPa with an inclined ebulliometer. The experimental results are analysed using the UNIQUAC equation with temperature-dependent binary parameters with satisfactory results.Vapor-liquid equilibriaalpha-pineneoctaneUNIQUAC481120-11211.alpha.-pineneC10H161Commercial source199.804Gas chromatography2octaneC8H181Commercial source199.854Gas chromatography11Principal objective of the workJCEJCE9/20/20031Mass density, kg/m3Vibrating tube methodLiquidDirect value, XLiquidPressure, kPa101.32561Temperature, K1293.1551858.06511Principal objective of the workJCEJCE9/20/20031Refractive index (Na D-line)Standard Abbe refractometryLiquidDirect value, XLiquidPressure, kPa101.32561Temperature, K1293.15511.4657511Principal objective of the workJCEJCE9/22/20031Vapor or sublimation pressure, kPaEbulliometric method (Recirculating still)LiquidDirect value, XLiquidGas1Temperature, K1348.15517.3531363.155113.3241383.155126.9841382.795126.6641405.545153.3341429.2451101.32521Principal objective of the workJCEJCE9/20/20031Mass density, kg/m3Vibrating tube methodLiquidDirect value, XLiquidPressure, kPa101.32561Temperature, K1293.1551702.44521Principal objective of the workJCEJCE9/20/20031Refractive index (Na D-line)Standard Abbe refractometryLiquidDirect value, XLiquidPressure, kPa101.32561Temperature, K1293.15511.3973521Principal objective of the workJCEJCE9/22/20031Vapor or sublimation pressure, kPaEbulliometric method (Recirculating still)LiquidDirect value, XLiquidGas1Temperature, K1348.155119.3141363.155133.5241383.155164.2541356.745126.6641376.955153.3341398.7951101.3251121Principal objective of the workJCEJCE9/20/20031Vapor or sublimation pressure, kPaEbulliometric method (Recirculating still)LiquidDirect value, XLiquidGas1Temperature, K2Mole fraction1Liquid1348.155200119.3141348.1552.11214118.2141348.1552.20214117.0241348.1552.25294116.5941348.1552.30344115.9841348.1552.3994114.8641348.1552.50154113.7541348.1552.59944112.5141348.1552.80034110.0541348.1552.8966418.7431348.15521517.3531363.155200133.5241363.1552.11214131.2641363.1552.20214129.7141363.1552.25294128.6341363.1552.30344127.4741363.1552.3994125.6741363.1552.50154123.6541363.1552.59944121.441363.1552.80034117.5441363.1552.89664115.6541363.155215113.3241383.155200164.2541383.1552.11214161.5741383.1552.20214157.1841383.1552.25294155.0841383.1552.30344152.9641383.1552.3994149.6941383.1552.50154145.5441383.1552.59944141.0141383.1552.80034134.5141383.1552.89664130.6741383.155215126.9841121Principal objective of the workJCEJCE9/21/20031Boiling temperature at pressure P, KEbulliometric method (Recirculating still)LiquidDirect value, XLiquidGas1Pressure, kPa2Mole fraction1Liquid126.6642001356.745126.6642.112141358.095126.6642.202141359.625126.6642.252941360.645126.6642.303441361.85126.6642.39941363.735126.6642.501541366.085126.6642.599441369.125126.6642.800341375.675126.6642.896641378.945126.6642151382.795153.3342001376.955153.3342.112141378.695153.3342.202141381.295153.3342.252941382.525153.3342.303441383.065153.3342.39941385.895153.3342.501541388.925153.3342.599441392.375153.3342.800341398.925153.3342.896641401.825153.3342151405.545
