✦ Synopsis

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