Research on the chemical and physical phenomena occurring between coal and solvents prior to the onset of the major liquefaction (bond breaking) step, particularly those phenomena that occur readily at temperatures below 200/sup 0/C and have an effect on the subsequent liquefaction reactions, are described. Previously reported experiments had indicated that small but experimentally significant increases in coal conversion could be obtained by heating the coal-solvent slurry for 1 hour at 200/sup 0/C prior to liquefaction. The solvents selected for pretreatment studies were quinoline, 1-methylnaphthalene, tetrahydrofuran, and cyclohexane. (BLM)
