The price of coal in the U.S. is declining due to the reduction in U.S. dependence on coal-burning to meet energy consumption needs. Despite the diminishing rate of coal production in the U.S., coal is a resource in great abundance and the necessary infrastructure for coal mining is accessible. Thus, methods to increase the value of low-price, raw coal are sought. When compared to coals from other U.S. basins, coal from the Powder River Basin (PRB) is particularly inexpensive due to its plenitude and lower heat output upon burning. PRB coal has a relatively high oxygen content and extracting the organic components of PRB coal yielded molecules with multiple hydroxyl groups. The highly functionalized PRB coal extract was then adopted as a polyol in the synthesis of polyurethane (PU) via reflux reactions and pressure-bomb reactions. The resulting PUs possess high yield strength and greater resistance to thermal degradation than most commercially available polymers. Adhesives, coatings, and foams have all been formed from coal derived PUs, highlighting the versatility and potential commercial applications of these materials.
