The results reported indicate that the low molecular weight olefins (ethylene, propylene and butadiene) which are major gaseous hydrocarbon products of flash pyrolysis of coal derive from the same precursors in coal, whereas methane, benzene and other pyrolysis products are mainly formed from differ
The pyridine-insoluble residues of telocollinites and sporinites previously separated from British Carboniferous coals have been investigated further. Treatment with alkaline-ethane-l:2 diol at 300Β°C gave only a few per cent of soluble material. 13C CP/MAS n.m.r. spectra of the insoluble residues co
