This paper presents the results of measurements of the vapor pressures of large polycyclic aromatic hydrocarbons (PAH), including those containing heteroatoms, and some mixtures of these compounds. The work was motivated by the lack of vapor pressure data on coal tars, which tend to have a highly aromatic nature and which also contain significant numbers of heteroatoms. Relatively few data are available on the vapor pressures of large polycyclics containing heteroatoms. Knowledge of coal tar vapor pressures is important in predicting the pyrolysis behavior of coals, since most advanced models of coal pyrolysis utilize an evaporation step to describe the loss of tar from the particles.
