Development of Abraham model expressions for predicting the standard molar enthalpies of vaporization of organic compounds at 298.15 K

摘要: Abstract Published experimental standard molar enthalpies of vaporization data at 298.15 K have been compiled from the chemical and engineering literature for 703 liquid organic organometallic compounds. The are used to develop predictive expressions based on Abraham model. derived correlations provide reasonably accurate mathematical descriptions observed vaporization. Standard deviations between back-calculated order 2.2 kJ mol−1, which is comparable (if not better than) many existing methods. can be estimate additional compounds 298.15 K, provided that model compound descriptors known.
