✦ Synopsis

Reaction of coal with boron trifluoride destroys caking properties without simultaneously affecting the intensities of 'aromatic' i.r. absorption bands between 700 and 900 cm-l and/or lowering the yields of chloroform-soluble matter obtainable after rapid heating to ~400'C.

It is therefore contended that chloroform-solubility and 'aromatic' i.r. absorption are not necessarily indicative of caking propensities or, alternatively, that such propensities depend more on the chemical quality than on the quantity of chloroformsoluble matter.
