✦ Synopsis
The presence of aggregated structures in pyridine coal extracts are indicated by small angle neutron scattering studies of coal-extract solutions. However, no such aggregated structures exist in coal extracts with a carbon disulfide-N-methyl-2-pyrrolidane mixed solvent, which may indicate that. in a thermodynamic sense. pyridine is not such a good solvent for coal.
