Research focused on completion of all experimental runs on 7 of the 8 coals from the Argonne Premium Coal collection. Data on the conversion of these coals to THF-, toluene-, and hexane-solubles were collected at reaction times of 5 and 40 minutes, and in 5 different vehicles. Naphthalene, 1-methylnaphthalene, and phenanthrene were employed as model aromatic vehicles (solvents), and tetralin and 9,10-dihydrophenanthrene as model hydroaromatic vehicles. The data for relative reactivity of the five bituminous coals tested show complete internal consistency within each of the two solvent classifications. Between solvent groupings (donor vs non-donor), some reactivity shifts are present, thus reinforcing our initial hypothesis concerning solvent effects on reactivity. The reactivity data for the subbituminous and lignite coals tested from the Argonne suite show very strong solvent dependency, and are further confused by the effect of water. The effect of reaction time on reactivity ranking was also explored. These data indicate the importance of considering both reaction statics and dynamics when formulating reactivity definitions. Preliminary correlations utilizing both static and dynamic reactivity definitions were investigated for the coals from the Argonne suite, but these efforts were hampered by a lack of the required data on these coals. All experimental work on the 22 coals from the Penn State Premium coal collection was completed, and data reduction for purposes of reactivity correlation was initiated. 4 refs., 19 figs.
