Anthracite, bituminous and subbituminous coal when treated with naphthalene anion in tetrahydrofuran added negativecharges to form the corresponding coal anions. Alkylation of bituminous and subbituminous coal anion with ethyl iodide resulted in the addition of 16 and 14 ethyl groups per 100 carbon

Pocahontas (Ivb) coal, when treated with alkali metal in tetrahydrofuran in the presence of a small amount of naphthalene, is converted to a 'coal anion'. The coal anion is formed by transfer of negative charges from the alkali metal to the aromatic clusters in coal with naphthalene acting as an ele

The reaction of non-reductive ethylation of a coal anion generated in the presence of a strong base (sodium and/or potassium amides) in liquid ammonia is an efficient method for coal solubilization. Under the reaction conditions used, over 50 wt y0 of vitrinites separated from carboniferous bitumino
