EXTRACTION ENHANCEMENT OF COAL THROUGH CHEMICAL REACTIONS WITH CETENE AND CETANOL IN THE ANTHRACENE OIL UNDER ATMOSPHERIC PRESSURE CONDITIONS

Assam coal has been reacted with cetene or cetanol in anthracene oil. These reactions were attempted to alkylate the coal in the absence of a catalyst under the conditions of extractive disintegration of coal. Coal derived chemicals were used in the reactions as far as possible. The reactions resulted in enhancing the extractability of coal in quinoline by more than 70-90%. These reactions resulted in the alkylation of coal and increase of carbon contents in coal along with the addition of nitrogenous bases from anthracene oil to coal.
