Critical point measurement of some polycyclic aromatic hydrocarbons

“…The method of Avaullee et al [26] was chosen because it gives, as we shall see later, a good estimation of the critical temperatures of PAH's studied while the method of Jiao et al a The uncertainties are the combined expanded uncertainty at the 95% level of confidence. b The average of the values given in reference [29][30][31]. c The average of the values given in reference [29][30][31][32] and calculated from Ref.…”

“…b The average of the values given in reference [29][30][31]. c The average of the values given in reference [29][30][31][32] and calculated from Ref. [33].…”

“…[33]. d The average of the values given in reference [29,[34][35][36][37]. e The average of the values given in reference [29,31,37].…”

“…d The average of the values given in reference [29,[34][35][36][37]. e The average of the values given in reference [29,31,37]. f The average of the values given in reference [31] and calculated from the Antoine equation [13].…”

“…Using the experimental values is of course preferable. It is obvious that the accuracy of estimation by the methods of Wilson and Jasperson, Nannoolal et al, and Avaullee et al highly depends on the accuracy with which the normal boiling point is determined.The normal boiling temperature of acenaphthene was measured by Perkin[28] (T nb = 502.7 K), Mortimer and Murphy[29] (T nb = 550.3 K), and Belousova et al[30] (T nb = 550.6 K). The supplier of the samples we used, Alfa Aesar, gives for T nb of acenaphthene T = 551.15 K [31].…”
