Removing coal Radicals by Chemical Reduction

摘要

The radial population of Wyodak coal was decreased by reaction with the reducing agents SmI_2, YbI_2, and CrCI_2. The latter is the most effective, removing 67/100 of the radicals. It is also The easiest to prepare. The swelling of Wyodak coal in toluene, the, and pyridine is independent Of the coal's radical population demonstrating that radical sites are not responsible for Intermolecular associative interactions.
