Bond cleavage reactions of the bridge structure in coal are known to be key steps for coal conversion like liquefaction, carbonization, and so on. In the present study, we investigated two kinds of bond cleavage reactions, homolytic cleavage of dimethylene and ether bonds, and ipso-position cleavage of mono- and dimethylene bonds in the presence of hydrogen donor solvent (9,10-dihydroanthracene and 9,10-dihydrophenanthrene). The results suggest that cleavage reaction at ipso-position is also important at temperature range around 420℃.
