Choi, C; Stock, L M

The samples used for the comparison of the influence of maceral concentrates on the exchange reactions between tetralin-d/sub 12/ and diphenylmethane were prepared by density gradient centrifugation or float-sink techniques. The highly purified macerals selectively enhanced the rate of exchange reaction at the benzylic position of tetralin-d/sub 12/. The order of reactivity, exinites > vitrinites> inertinites, was clearly established for the macerals of the PSOC-106 coal. Generally the same reactivity was noted for the less pure macerals obtained from PSOC-828 and PSOC-1103 coals, but the differences in reactivity were less sharply defined. (BLM)
