摘要: Abstract An analysis for polymethylene moieties in purified coal macerals has shown the (CH 2 ) n ( where ⩾5) content, by a liquefaction— 1 H n.m.r. method, to be highest exinite and lower vitrinite inertinite macerals. From any particular coal, content of was higher than but exinite. Pyrolysis these gave ethylene yields proportional content.
