摘要：

Scanning electron microscopy of particles of three bituminous coals (78.5% C, 81.7% C and 89.9% C d.a.f.) which had been treated with pyridine, methanol, bromine, air, sulfuric acid, ammonia and alkylating agents showed that the reagents produced significant changes in the morphology of the particles. The particles cracked and disintegrated in ways which appear to be characteristic of the disruption of hydrogen bonding, the volume and thermal changes accompanying local reactions and of the breakage of C-C bonds.
