โœฆ Synopsis


Three Polish coal samples (flame coal, gas coal and orthocoking coal) and their macerals were studied in the solid state by means of 13C cross polarization/magic angle spinning n.m.r. and FT-i.r. spectroscopies. Several structural parameters derived from these analyses allow the characterization of the three macerals, vitrinite, exinite and fusinite, and their comparison with their parental coal. These structural data were compared with the solvent extraction yields of the same samples with N-methyl 2-pyrrolidone.

The quantitative aspects of cross-polarization (CP), which is used in conjunction with dipolar decoupling and magic-angle rotation to obtain high resolution 13C n.m.r. spectra of coals, have been studied using a bituminous coal (82 wt% C, dmmf basis) and asphaltenes from an extract of the same coal.

## Magic-angle 13C n.m.r. spectra have been obtained for a series of vitrinite concentrates. Proper modification of the cross-polarization pulse sequence allows separation of protonated and nonprotonated carbon resonances. This technique is used to determine the relative fraction of nonprotonated
