Abstract
The treatment of coal with tetralin as an alkyl acceptor has been carried out in the presence of a super acid catalyst (trifluoromethane sulfonic acid) to yield highly extractable and readily liquefiable products. The solubility in pyridine of the coal recovered from this reaction was increased significantly (to over 90%). Better correlation between the solubility of treated coal and the amount of tetralin introduced by transalkylation has been obtained. Model compound reactions have also been carried out to clarify the mechanisms of coal reaction. The results indicate that cleavage of methylene bridge cross-linked aromatic rings occurs more readily than those of ethylene and biaryl bonds. In this reaction system, some side-reactions which hindered the process of coal solubilization took place in competition with transalkylation reactions.
