Reactions governing coal solubilization. Sixth quarterly report, October 15, 1984-January 15, 1985

; ;

Modified density gradient centrifugation of previously prepared maceral concentrates yielded large quantities of pure maceral fractions. Two hvA bituminous coals and their maceral fractions were examined by Fourier transform infrared spectroscopy. There were major differences between different maceral groups, i.e., the exinites and the vitrinites, but clear similarities in the macerals, i.e., the vitrinites from PSOC-726 and PSOC-732, of the two coals. Alkylation in presence of a phase transfer catalyst was carried out for various rank coals. Elemental analyses for the raw coals and alkylated products were obtained. The C/sub 100/ formulation for the raw coals and the alkylated products were calculated from the analyses. The number average molecular weights of reduced and reductively alkylated PSOC-1197 were obtained by vapor pressure osmometry. 17 references, 8 figures, 9 tables.
