A quantiative analytical method for the basic functionality in coal, a pyridinium functionarity has been developed. This method is composed of two-steps treatment. The first one is the formation of the acid-bace complex with the basic funcutionalities and the strong acid. And the secound step is the determination of the acid in the complex by non-reversable and quantitative chemical reaction with Tetra-n-butylammonium borohydride in pyridine solvent.
