The effect of decomposition of oxygen-functional groups on coal liquefaction was investigated by means of quantitative analysis of oxygen-functional groups and by CP/MAS^<13>CNMR. In the case of pretreatment at 400〜430℃ in 1-Methyl naphthalene, ether crosslinking like a dibenzofuran was formed by dehydration of phenolic hydroxyl gruop and THFI yield increased in following liquefaction reaction. The addition of donor solvent like a Tetralin decreased the formation of ether crosslinking and decreased THFI yield in following liquefaction reaction.
