ABSTRACT
In this work samples of Colombian coal of the mines of La Loma (Cesar) and Cogua (Cundinamarca) were swollen and extracted with 6 different solvents, to evaluate secondary interactions. The best swelling solvent for La Loma coal was monoethanolamine, MEA, (Q = 2,6); other solvents had lower values because of their smaller polarity and basicity. The swelling order for this coal was: Heptane
