This paper presents data on the vapor pressure of a pyrolysis tar produced from Bruceton high volatile bituminous coal. The data were obtained using the non-isothermal Knudsen effusion method, and are presented as a function of the molecular weight of the tar. The results are consistent with data we presented earlier on another high volatile bituminous coal. Data on mixtures of another high volatile bituminous coal tar and 1-hydroxypyrene strongly suggest the role of phenolic hydroxyls in the tars from high volatile bituminous coals, and this is consistent with the measured enthalpies of evaporation of the tar mixtures.
