Abstract: | A method of analysis for polymethylene compounds in coal is described, based on liquefaction of the coal in tetrahydroquinoline and running the 1H n.m.r. spectrum of the liquefaction products in CDCl3. It is shown that the (CH2)n content determined in this way is proportional to the ethylene, propylene and butadiene yields produced on flash pyrolysis of the coals at 850 °C. |
