Abstract
Asphaltenes, the key intermediates in the liquefaction of bituminous coals, consist of hydrogen bonded complexes which can be separated into their acidic and basic components. The acidic components contain all, while the basic components contain none, of the exchangeable protons present. The significance of these findings with respect to coal structure and coal solubilization is discussed.Keywords
