Abstract:	New data on coal tar oils and data from the literature on pure compounds and oils derived from coal were used for testing the predictions by the correlation of Maxwell—Bonnell. Based on the observation that the discrepancies between the predicted values and the data are systematic, recommendations were deduced on needed modifications to the correlation. A proposal for modification to the Maxwell and Bonnell correlation to improve prediction of vapor pressures of highly aromatic fuel fractions with characterization factors of8 UOPK 10.5 was made. Experimental data were taken on vapor pressures of fractions of coke oven coal tar oils and of a sample of oil derived from coal liquefaction by the SRC-II process. Several coal derived oils were separated into fractions in batch distillations. The fractions were characterized and analyzed, and their vapor pressures within the range of 2 to 800 torrs were measured. A proposed modification for the Maxwell-Bonnell correlation was part of this study.
