LOW VAPOR-PRESSURES OF 12 AROMATIC-HYDROCARBONS - EXPERIMENTAL AND CALCULATED DATA USING A GROUP-CONTRIBUTION METHOD

As an extension to our previous work carried out on the measurements o f vapor pressures for cycloalkanes [I. Mokbel, E, Rauzy, H. Loiseleur, C. Berro, J. Jose, Fluid Phase Equilibria, 108 (1995) 103] and polycy clic aromatic hydrocarbons [I. Mokbel, T. Guetachew, J. Jose, Eldata, Int. Electron. J. Phys. Chem. Data (1995) 167] we have performed a sim ilar study for 12 aromatic hydrocarbons in the range 1 Pa to 200 kPa. The experimental results correlated with Wagner's equation are in a go od agreement with the available literature data. Experimental vapor pr essures were then represented and predicted with a group contribution method. (C) 1998 Elsevier Science B.V. All rights reserved.
